2017Co-Authors: Bettina Heuchert, Uwe Braun, Natalia Tkach, Denise Marx, Martin RoserAbstract:Abstract: Heuchert, B., Braun, U., Tkach, N., Marx, D. & Roser, M. 2017: Biography of D. F. L. von Schlechtendal and Type material of his new taxa preserved in the herbarium of Martin Luther University Halle-Wittenberg (HAL) and other botanical Collections. Schlechtendalia 31 : 1–143. D. F. L. von Schlechtendal (1794–1866) was professor of botany and director of the botanical garden in Halle (Saale) from 1833 to 1866. He was one of the leading and most productive German botanists of the 19th century, who, inter alia, introduced about 1,600 new taxa, most of them new species, including 78 new genera. Schlechtendal‟s private herbarium was purchased by the university after his death from his widow and represents the historical nucleus of the present-day herbarium of the Martin Luther University (HAL). Based on Schubert‟s (1964) unpublished dissertation and other sources, Schlechtendal‟s life and work is outlined. All taxa described by Schlechtendal are summarized in an annotated list, including details of Type Collections preserved in the herbarium of Martin Luther University Halle-Wittenberg and in other botanical Collections. Previous typifications of the taxa concerned were scrutinized in the light of the rules of the Internal Code of Nomenclature for Algae, Fungi, and Plants. The following taxa are lectotypified: Acacia clavata, A. cyclophylla, Ammania catholica, Annona globiflora, Aspidium thelypteris var. squamigerum, Atragene wenderothii, Bouvardia houtteana, Brunia passerinoides, Bupleurum brevicaule, Castilleja arvensis, Cestrum oblongifolium, Chloris meccana, Condalia mexicana, Convolvulus polyanthus, C. variabilis, Cordia ambigua, Croton conspurcatus, C. draco, C. ehrenbergii, C. pseudochina, C. pseudochina var. minor, Cuphea linarioides, Desmodium affine, Diodia polymorpha, Elaphrium simplicifolium, Epilobium repens, Eryngium deppeanum, Eugenia macrocarpa, Exostema formosum, Galium cotinoides, G. obstipum f. angustifolium, Geophila reniformis var. asiatica, Grevillea behrii, Halgania strigosa, Hydrocotyle calliodus, H. mexicana, Hypericum campestre, Lisianthius saponarioides, Myrtus capuli, M. trunciflora, Niphogeton andicola, Peperomia asarifolia, Physalis nicandroides, Potentilla nivea var. camtschatica, Smilax medica, Stachys boraginoides, Tauschia nudicaulis, Trichomanes melanotrichum, Veratrum frigidum, Veronica alpina L. var. unalaschcensis, and Viola ciliata. Borreria scabiosoides is neotypified. Zusammenfassung: Heuchert, B., Braun, U., Tkach, N., Marx, D. & Roser, M. 2017: Biographie von D. F. L. von Schlechtendal und Typusmaterial seiner neuen Taxa, die im Herbarium der Martin-Luther-Universitat Halle-Wittenberg (HAL) und anderen botanischen Sammlungen erhalten sind. Schlechtendalia 31 : 1–143. D. F. L. von Schlechtendal (1794–1866) war von 1833 bis 1866 Professor fur Botanik und Direktor des Botanischen Gartens in Halle (Saale). Er war einer der fuhrenden und produktivsten deutschen Botaniker des 19ten Jahrhunderts, der unter anderem etwa 1600 neue Taxa eingefuhrt hat, die meisten davon Arten, einschlieslich 78 neuer Gattungen. Schlechtendals privates Herbarium wurde nach seinem Tod durch die Universitat von seiner Witwe gekauft und stellt den historischen Grundstock des heutigen Herbariums der Martin-Luther-Universitat dar. Auf Grundlage der unveroffentlichten Dissertation von Schubert (1964) und anderer Quellen wird Leben und Werk von Schlechtendal dargestellt. Alle von Schlechtendal beschriebenen Taxa sind in einer annotierten Liste zusammengefasst, einschlieslich detaillierter Angaben zu Typus-Kollektionen, die im Herbarium der Martin-Luther-Universitat und anderen botanischen Sammlungen aufbewahrt werden.

Type material in the herbarium of the martin luther university halle wittenberg of species based on Collections from alexander von humboldt s american expedition between 1799 and 1804 in its historical context
Schlechtendalia, 2016Co-Authors: Natalia Tkach, Uwe Braun, Bettina Heuchert, Christina Kruger, Heike Heklau, Denise Marx, Martin RoserAbstract:Abstract: Tkach, N., Heuchert, B., Kruger, Ch., Heklau, H., Marx, D., Braun, U. & Roser, M. 2016: Type material in the herbarium of the Martin Luther University Halle-Wittenberg of species based on Collections from Alexander von Humboldt’s American expedition between 1799 and 1804 in its historical context. Schlechtendalia 29 : 1–107. Type material of 363 plant species described on the basis of Collections from Alexander von Humboldt’s American research journey at the turn from the 18th to the 19th century is deposited in the herbarium of the Martin Luther University Halle-Wittenberg (HAL). Most of these Types are duplicates of specimens in Willdenow’s collection housed in the herbarium of the Botanical Garden and Botanical Museum, Berlin-Dahlem (B). Some other samples came from the legacy of D. F. C. von Schlechtendal, but most of these specimens made their way to Halle through his son, D. F. L. von Schlechtendal. Numerous Humboldt Collections are deposited in the herbarium of the Museum National d’Histoire Naturelle in Paris (P). A comprehensive survey of the Types deposited in HAL is given, and the herbarium samples concerned are discussed in their historical context. It has been verified whether the Type specimens deposited in HAL are unique specimens or duplicates of samples preserved also in Berlin (B) and/or Paris (P). The history of Humboldt’s botanical Collections from his American expedition, including their shipment to Europe, all important people involved their distribution between Berlin and Paris, their scientific processing by various botanists, and the background of the transfer of duplicates to Halle, are discussed. An annotated list of the 363 Type Collections is provided at the end of this work. Zusammenfassung: Tkach, N., Kruger, Ch., Heuchert, B., Heklau, H., Marx, D., Braun, U. & Roser, M. 2016: Typusmaterial von Arten basierend auf Kollektionen von Alexander von Humboldts amerikanischer Forschungsreise zwischen 1799 und 1804 im Herbarium der Martin-Luther-Universitat Halle-Wittenberg im historischen Kontext. Schlechtendalia 29 : 1–107. Typusmaterial von 363 Pflanzenarten, die auf Grundlage von Kollektionen aus Humboldts amerikanischer Forschungsreise an der Wende vom 18. zum 19. Jahrhundert beschrieben worden sind, befindet sich in Herbarium der Martin-Luther-Universitat Halle-Wittenberg (HAL). Die meisten Typen sind Dubletten von Kollektionen aus der Sammlung von C. L. Willdenow im Herbarium des Botanischen Gartens und Botanischen Museums Berlin-Dahlem (B), einige andere Belege stammen aus dem Nachlass von D. F. C. von Schlechtendal, wobei aber die meisten dieser Kollektionen durch seinen Sohn, D. F. L. von Schlechtendal, nach Halle gelangten. Zahlreiche Humboldt-Kollektionen werden im Herbarium des Museum National d’Histoire Naturelle in Paris (P) aufbewahrt. Eine umfassende Ubersicht der in HAL vorhandenen Typus-Kollektionen wird vorgelegt und die einzelnen Belege werden in ihrem historischen Kontext diskutiert. Es wurde gepruft, ob die in HAL vorhandenen Typen Unikate sind oder Duplikate von Belegen, die in Berlin (B) und/oder Paris (P) vorhanden sind. Die Geschichte von Humboldts botanischen Sammlungen seiner amerikanischen Expedition, einschlieslich des Transports nach Europa, aller wichtigen involvierten Personen, der Aufteilung zwischen Berlin und Paris, der wissenschaftlichen Bearbeitung durch verschiedene Botaniker und des Hintergrundes der Uberfuhrung von Dubletten nach Halle, werden diskutiert. Eine annotierte Liste der 363 Typen bildet den Abschluss dieser Arbeit.

The diversity of cercosporoid hyphomycetes - new species, combinations, names and morphological clarifications
Fungal Diversity, 2007Co-Authors: Uwe Braun, P.w. CrousAbstract:The new species Stenella leucothoes and S. pittospori are described, and the new combinations and new names Asperisporium rafinesquiae, Passolora euphorbiicola, P. sterculiacearum, Pseudocercospora campanulae, P. lonicerigena, P. photiniae-serrulatae, P. physostegiae and Stenella prosopidis are introduced. Based on re-examinations of Type Collections, the taxonomic status of Cercospora saccharini and C. rhagadioli as genuine species of Cercospora, morphologically distinct from C. apii s. l., could be confirmed, and it could be demonstrated that Cercospora pittospori had been correctly reallocated to Pseudocereospora. Furthermore, the nomenclature of Passalora polygonati-maximoviczii, Pseudocercospora dendrobii and P. sacchari is discussed, the status of Cercospora solani-nigri as a synonym of Pseudocercospora atromarginalis is verified, and new records of Passalora bocconiae and Pseudocercospora thouiniae are added.

Re-assessment of the Type Collections of Maslov's species of Hapalidiales (Rhodophyta). Species originally attributed to Lithothamnium, Mesophyllum and Palaeothamnium
Spanish Journal of Palaeontology, 2020Co-Authors: Juan C. Braga, Davide Bassi, Elena Zakrevskaya, Julio Aguirre, Eleonora P. RadionovaAbstract:This is the third and last paper of a series devoted to the revision of the Types of the species and infra-specific taxa of coralline red algae established in two monographs by Maslov. Maslov’s new species and intraspecific taxa were separated by characters of questionable significance from a modern taxonomic point of view. In this study, as un previous contributions, a number of Types of fossil coralline algae Maslov’s original collection are re-assessed with a modern morpho-anatomic taxonomic approach. This paper deals in particular with the Types of species attributed of Maslov to the genera Lithothamnion (as Lithothamnium), Mesophyllum and Palaeothamnium (Hapalidiales, Rhodophyta). According to our reassessment, only the Type of Mesophyllum schenckii var. corticesum can be confidently assigned to a currently accepted genus within the family Hapalidiaceae, subfamily Melobesioideae. The Types of Lithothamnion iorii, Palaeothamnium kassovense, Mesophyllum kutense, Lithothamnion microcellulosum, Lithothamnion praefructiculosum, and Lithothamnion thcernomoricum possess multiporate conceptacles and non-coaxial ventral core and can be attributed to the subfamily Melobesioideae. The lack of ephitallial cells, however, prevents any precise generic assignment within the Lithothamnion, Phymatolithon, Clathtomotphum and Synarthrophyton complex. Finally, the lack of significant characters prevents any confident attribution of the Type of “Lithothamnion saxorum var. korolukae” to any defined generic or suprageneric taxon within the Hapalidiales or the Corallinales. The absence of reproductive structures int ye Types of “Lithothamnion caucasicum”, “Lithothamnion (?) intergeminum” and “Lithothamnion (?) suhumii” prevents the placement of these taxa in any order and family within Hapalidiales, Corallinales or Sporolithales

re assessment of the Type Collections of fourteen corallinalean species corallinales rhodophyta described by w ishijima 1942 1960
Palaeontology, 2009Co-Authors: Yasufumi Iryu, Davide Bassi, William J. WoelkerlingAbstract:Abstract: Many species of fossil coralline algae have been separated on the basis of only a few characters with slight or doubtful taxonomic significance. Analysis of the Type material of the fossil coralline algal species is, therefore, needed in order to assess the taxonomic status and circumscription of these taxa. Wataru Ishijima has been one of the most prolific Japanese palaeontologists who worked on fossil calcareous algae from the western Pacific region. Ishijima described a large number of new taxa of fossil calcareous algae mostly belonging to the Corallinales from Eocene to Pleistocene sedimentary successions. An analysis of some of Ishijima’s Types of Corallinales (Rhodophyta) described from 1942 to 1960, currently housed in the Institute of Geology and Paleontology, Graduate School of Science, Tohoku University, Sendai (Japan), is presented. For fourteen taxa, changes were made to previously published statements of typification. Re-examination of the Types from a modern perspective of coralline algal taxonomy reveals that Hydrolithon taishakuensis (Ishijima) comb. nov (= Lithothamnium taishakuensis), Sporolithon kobamazimensis (Ishijima) comb. nov. (= Archaeolithothamnium kobamazimensis), Sporolithon kuboiensis (Ishijima) comb. nov. (= Archaeolithothamnium kuboiensis) and Sporolithon taiwanensis (Ishijima) comb. nov. (= Archaeolithothamnium taiwanensis) showed significant features justifying their use as species names. No diagnostic characters occur in two Types (L. nishiwadai, L. otsukiensis) and therefore the taxonomic disposition of these taxa remains unknown. Lithophyllum quadratum Ishijima is considered as a species of uncertain status within Lithophyllum pending further study. Lithoporella crassa Ishijima and Lithoporella hayasakai Ishijima are considered heterotypic synonyms of Lithophyllum prototypum (Foslie) Foslie, while Porolithon hanzawai Ishijima is a heterotypic synonym of Hydrolithon onkodes (Heydrich) Penrose and Woelkerling. Mesophyllum arakuraensis Ishijima is co-specific to, and has nomenclatural priority over, M. contii Ishijima. However, M. arakuraensis and M. contii do not show evidence whether either might belong to Synarthrophyton instead of Mesophyllum. Lithothamnion ishizuchiensis Ishijima and L. kasedaensis Ishijima have no diagnostic features that can be used to ally them to any particular genus or species of Melobesioideae.

RE‐ASSESSMENT OF THE Type Collections OF CORALLINALEAN GENERA (CORALLINALES, RHODOPHYTA) DESCRIBED BY V. P. MASLOV
Palaeontology, 2005Co-Authors: Davide Bassi, Juan C. Braga, Elena Zakrevskaya, Eleonora P. RadionovaAbstract:From 1935 to 1962 Maslov published two mono- graphs and several other papers on the taxonomy of fossil cal- careous algae of diverse ages from the large geographical area of the former USSR. Among many other taxa, he described five new genera (Solenophyllum, Palaeophyllum, Mesolithon, Bicorium and Tomilithon, as a subgenus of Parachaetetes Den- inger) which he attributed to the Corallinaceae, and the new genus Karpathia, which he included in the Squamariaceae. Type material of these taxa, except for Mesolithon, is housed in the Geological Institute of the Russian Academy of Sci- ences, Moscow. Re-examination of the genus Types from a modern perspective of coralline algal taxonomy shows that Karpathia is a validly published genus of corallinaceans (subfamily Mastophoroideae) to which several Cenozoic fossil species can be assigned. In contrast, the holoType of P. elegans, the Type species of Palaeophyllum, cannot be assigned to any subfamily within the Corallinaceae and its pre- served features are inadequate for confidently delimiting a sep- arate genus. Solenophyllum is a valid genus in which Palaeozoic representatives of Corallinales formerly attributed to Parachae- tetes Deninger can be included. Tomilithon is considered a younger heterotypic synonym of Solenophyllum. The algal nature of the bioclasts in the Type of Bicorium is uncertain.

Lithoporella crassa Ishijima and Lithoporella hayasakai Ishijima are considered heterotypic synonyms of Lithophyllum prototypum (Foslie) Foslie, while Porolithon hanzawai Ishijima is a heterotypic synonym of Hydrolithon onkodes (Heydrich) Penrose and Woelkerling. Mesophyllum arakuraensis Ishijima is co-specific to, and has nomenclatural priority over, M. contii Ishijima. However, M. arakuraensis and M. contii do not show evidence whether either might belong to Synarthrophyton instead of Mesophyllum. Lithothamnion ishizuchiensis Ishijima and L. kasedaensis Ishijima have no diagnostic features that can be used to ally them to any particular genus or species of Melobesioideae.

a molecular and morphological analysis of the genus rhizopogon subgenus villosuli section villosuli as a preface to ecological monitoring
Mycologia, 2014Co-Authors: Ryan Bubriski, Peter G KennedyAbstract:Rhizopogon (Boletales) represents a model genus for ecological studies of ectomycorrhizal fungi, but the identification of species in subgenus Villosuli section Villosuli has long been challenging due to variation in taxonomically informative morphologi- cal characters. Here we re-examine species concepts in this section using data from nuclear ribosomal internal transcribed spacer (ITS) and large subunit (LSU) sequences as well as spore measurements. Our phylogenetic analyses from 34 Type and non-Type Collections of eight species, including the seven currently recognized in this section, found consistent support for only three species-level clades. Each of the clades had a significantly different combination of mean spore widths and Q ratios using digital- assisted measurements, which suggests both molecu- lar and spore-based morphological approaches can be used to identify species in this section. Based on our analysis, we propose that only three species names be applied to future ecological studies: R. hawkerae, R. parksii and R. villosulus .W e considerR. subareolatus and R. colossus as taxonomic synonyms of R. hawkerae and R. pseudovillosulus, R. rogersii, R. villescens and R. zelleri as taxonomic synonyms of R. villosulus.
