Arthoniaceae with reddish, K+ purple ascomata in Japan
Phytotaxa, 2018Co-Authors: Andreas Frisch, Martin Grube, Hiroyuki Kashiwadani, Yoshihito OhmuraAbstract:Arthonia sanguinaria is described as new to science. The East Asian Arthonia lopingensis and the widely distributed Arthonia picea are reported as new to Japan from Honshu and the Ogasawara Islands, respectively. The phylogenetic position of A. picea , A. sanguinaria and Coniocarpon cinnabarinum from the Ogasawara Islands is shown by RAxML and Bayesian analysis of mtSSU, nLSU and RPB2 sequence data. Our results confirm the polyphyletic origin of quinoid pigments in Arthoniaceae. A key is presented to the Arthoniaceae with reddish ascomata in Japan.

The phylogenetic position of ConiArthonia and the transfer of Cryptothecia miniata to Myriostigma (Arthoniaceae, lichenized ascomycetes)
Phytotaxa, 2015Co-Authors: André Aptroot, Martin Grube, Damien Ertz, Jeanne Dos Reis Silva, Marcela Eugenia Da Silva CáceresAbstract:Two lichen species with bright orange and pink colours are described. ConiArthonia megaspora from NE Brazil, with relative large, hyaline ascospores that are becoming violet in tap water after release. The phylogenetic position of ConiArthonia is for the first time assessed, based on Brazilian specimens, and Arthonia eos and A. kermesina are combined into this genus. Fertile material of Cryptothecia miniata is for the first time described from Brazil and Costa Rica. A phylogenetic analysis including the epitype places it close to Myriostigma candidum in the recently resurrected genus Myriostigma . The genera Stirtonia and Cryptothecia in their current sense are shown to be both polyphyletic.

Unravelling the phylogenetic relationships of lichenised fungi in Dothideomyceta
Studies in Mycology, 2009Co-Authors: Matthew P. Nelsen, Robert Lücking, Martin Grube, Joelle Mbatchou, Lucia Muggia, E. Rivas Plata, H. T. LumbschAbstract:We present a revised phylogeny of lichenised Dothideomyceta (Arthoniomycetes and Dothideomycetes) based on a combined data set of nuclear large subunit (nuLSU) and mitochondrial small subunit (mtSSU) rDNA data. Dothideomyceta is supported as monophyletic with monophyletic classes Arthoniomycetes and Dothideomycetes; the latter, however, lacking support in this study. The phylogeny of lichenised Arthoniomycetes supports the current division into three families: Chrysothrichaceae (Chrysothrix), Arthoniaceae (Arthonia s. l., Cryptothecia, Herpothallon), and Roccellaceae (Chiodecton, Combea, Dendrographa, Dichosporidium, Enterographa, Erythrodecton, Lecanactis, Opegrapha, Roccella, Roccellographa, Schismatomma, Simonyella). The widespread and common Arthonia caesia is strongly supported as a (non-pigmented) member of Chrysothrix. Monoblastiaceae, Strigulaceae, and Trypetheliaceae are recovered as unrelated, monophyletic clades within Dothideomycetes. Also, the genera Arthopyrenia (Arthopyreniaceae) and Cystocoleus and Racodium (Capnodiales) are confirmed as Dothideomycetes but unrelated to each other. Mycomicrothelia is shown to be unrelated to Arthopyrenia s.str., but is supported as a monophyletic clade sister to Trypetheliaceae, which is supported by hamathecium characters. The generic concept in several groups is in need of revision, as indicated by non-monophyly of genera, such as Arthonia, Astrothelium, Cryptothecia, Cryptothelium, Enterographa, Opegrapha, and Trypethelium in our analyses.

Phylogenetic position of SynArthonia (lichenized Ascomycota, Arthoniaceae), with the description of six new species
Plant Ecology and Evolution, 2018Co-Authors: Dries Van Den Broeck, Andreas Frisch, Tahina Razafindrahaja, Bart Van De Vijver, Damien ErtzAbstract:Background and aims – The Arthoniaceae form a species-rich family of lichenized, lichenicolous and saprophytic fungi in the order Arthoniales. As part of taxonomic revisions of the African Arthoniaceae, a number of species assignable to the genus SynArthonia were collected and sequenced. The present study aims at placing the genus in a phylogeny for the first time and at clarifying its circumscription. Methods – Nuclear (RPB2) and mitochondrial (mtSSU) DNA sequences from freshly collected specimens were obtained and analysed with phylogenetic Bayesian and maximum likelihood (ML) methods. Key results – SynArthonia is closely related to the genera Reichlingia and Coniocarpon in the Arthoniaceae. Six SynArthonia species are described as new to science and ten new combinations into this genus are made. A worldwide identification key to the genus SynArthonia is provided. Lectotypes are chosen for Arthonia elegans, A. inconspicua, A. lopingensis, A. ochracea, A. subcaesia and A. translucens. Arthonia thamnocarpa is synonymized with Sclerophyton elegans, and Arthonia elegans with Coniocarpon fallax. SynArthonia ochracea is shown to be a misunderstood species in the past and recent literature, since it was erroneously synonymized with Coniocarpon elegans. SynArthonia ochracea appears to start its life cycle as a non-lichenized lichenicolous fungus on Graphis before developing a lichenized thallus or it might be a facultatively lichenicolous fungus. It belongs to a complex of closely related species whose biology and circumscription are still in need of further studies.Conclusions – SynArthonia forms a monophyletic but somewhat heterogeneous lineage closely related to Coniocarpon and Reichlingia. As delimited here, SynArthonia includes corticolous lichens with a trentepohlioid photobiont as well as non-lichenized lichenicolous fungi. The core group is characterized by white pruinose ascomata, but species producing orange pruinose or non-pruinose ascomata are also included. Ascospores are transversely septate with an enlarged apical cell or are muriform. Future molecular and morphological studies are needed for a better circumscription and definition of the genus.

Arthonia incarnata Arthoniaceae a rare and poorly known old growth forest lichen new to asia
Nordic Journal of Botany, 2017Co-Authors: Andreas Frisch, Göran Thor, Kwang Hee Moon, Yoshihito OhmuraAbstract:The rare and poorly known Northern Hemisphere old‐growth forest lichen Arthonia incarnata is reported for the first time for Asia from Japan and Korea. A detailed description and illustration is provided for the species based on the collections from Japan and South Korea. Bayesian and RAxML analyses of mtSSU, nLSU and RPB2 sequence data show A. incarnata to be only distantly related to the other Arthonia species hitherto sequenced and in particular to superficially similar species occurring in the same type of habitat such as A. didyma, A. spadicea and A. vinosa. For the analysis we generated new sequence data of A. incarnata for the mtSSU (5 specimens) and RPB2 (5) gene loci. Slight variation was observed in sequence data of the RPB2 gene between collections from eastern Asia and Sweden, but this is not substantiated by differences in morphology or ecological behaviour. Arthonia incarnata is confined to humid forests and only grows on parts of tree trunks shaded from precipitation and running water such as the lower side of leaning trunks or cavities at the base of trees. The species is found on trees with acidic bark, in eastern Asia mainly on Betula but also on coniferous trees and on dead wood. It was not found on bark of Salix (caprea), a common substrate for the species in Europe.

is stirtonia alba in north america resolving a nomenclatural impasse and assessing the taxonomic status of the Arthonia alba complex
The Bryologist, 2018Co-Authors: Gary B Perlmutter, Eimy Rivas Plata, Robert LückingAbstract:The invalid combination Stirtonia alba (Mull. Arg.) ined., based on Arthonia alba Mull. Arg., is listed for the continental United States in several important online repositories, including CNALH, USDA PLANTS and EOL. Although Arthonia alba belongs in Stirtonia, the name cannot be used in that combination, as it is blocked by S. alba Groenh. ex Makhija & Patw., a species described from Java, Indonesia, and both taxa are distinct morphologically, anatomically and chemically. Here, we resolve this nomenclatural impasse by proposing the new name S. caribaea for A. alba. We examined further material identified as “A. alba / S. alba” from North America and the Caribbean. Specimens ascribed to “S. alba (Mull. Arg.) ined.” from North America (Louisiana, Florida) were found to be misidentifications in other genera, with only one collection confirmed as a Stirtonia. This specimen was determined to be S. punctiformis, and is here reported as new to North America, representing a northward range extension from Central America and northern South America. Therefore, the name “Arthonia alba Mull. Arg.” listed under Stirtonia in the North American lichen checklist should be removed. Caribbean material previously identified as A. alba was found to represent two species: A. alba s.str., here renamed S. caribaea, known from Cuba and St. John of the U.S. Virgin Islands; and S. borinquensis, which we describe as a new species from Puerto Rico.

New species and further additions to the foliicolous lichen flora of Kenya (East Africa), including the first lichenicolous Aulaxina (Ostropales: Gomphillaceae)
Botanical Journal of the Linnean Society, 2002Co-Authors: Robert Lücking, Klaus KalbAbstract:An updated list of foliicolous lichens and their lichenicolous fungi known from Kenya (East Africa), chiefly based on a collection by the second author at three different localities, is presented. The new collections yielded 77 species, including three lichenicolous fungi, and two species and one subspecies are described as new: Arthonia pocsii Lucking & Kalb sp. nov., Asterothyrium septemseptatum subsp. africanum Lucking & Kalb ssp. nov. and Aulaxina aggregata Lucking & Kalb sp. nov.. The latter has also been found in material from Costa Rica and is the first known lichenicolous species in the genus. Porina atropunctata Lucking & Vezda is placed into synonymy with P. karnatakensis Makhija et al. and P. multiloculata Makhija et al. into synonymy with P. lucida R. Sant. Furthermore, the following two new combinations are proposed: Coenogonium tanzanicum (Vezda & Farkas) Lucking & Kalb comb. nov. [Bas. Dimerella tanzanica Vezda & Farkas] and Sporopodium pilocarpoides (Zahlbr.) Lucking & Kalb comb. nov. [Lopadium pilocarpoides Zahlbr.]. Byssoloma discordans (Nyl.) Vain., Calenia bullatinoides Lucking, Porina karnatakensis Makhija et al.Sporopodium citrinum (Zahlbr.) Elix, Lumbsch & Lucking, Sporopodium pilocarpoides (Zahlbr.) Lucking & Kalb, Strigula nigrocarpa Lucking, and the lichenicolous fungi Arthonia atropunctata Vain. and Gyalideopsis parvula Haf. & Vezda are new for the African continent (excluding Madagascar). The number of foliicolous lichen species known from Kenya is raised from 27 to 92, together with five lichenicolous fungi growing on them. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society, 2002, 139, 171–180.

enterographa confusa sp nov roccellaceae Arthoniales discovered by chance in type material of its host lichen Arthonia ochraceella described more than a century ago
Phytotaxa, 2018Co-Authors: Dries Van Den Broeck, Damien ErtzAbstract:Enterographa confusa is described as new to science from Cuba. It is characterized by a lichenicolous habit, punctiform ascomata immersed in the host thallus, (6–)8-spored asci and 3-septate ascospores of 17–23 × (2.5–)3 µm with a distinct gelatinous sheath of 1.5(–2) µm. The new species was discovered by chance in the thallus of type material of Arthonia ochraceella , which is lectotypified here. A detailed description of this latter is also provided. Enterographa confusa can be easily overlooked because of its tiny pale ascomata similar in colour to those of its host lichen. A key to all lichenicolous Enterographa species is presented.

two new species of Arthoniaceae from old growth european forests Arthonia thoriana and inoderma sorediatum and a new genus for schismatomma niveum
Lichenologist, 2018Co-Authors: Damien Ertz, Neil Sanderson, Anna łubek, Martin KukwaAbstract:Two new species of Arthoniaceae are described from old-growth European forests: Arthonia thoriana from Horner Combe in Great Britain and Inoderma sorediatum from the Bialowieza Forest in Poland. Phylogenetic analyses using mtSSU sequences were used to determine the generic affiliation of the two species. Arthonia thoriana is characterized by a non-lichenized white thallus, pallid brown, white pruinose ascomata of 0·12–0·30 mm diam., richly anastomosing paraphysoids and (1–2–)3-septate ascospores of 9–12×3·0–3·5 µm. Inoderma sorediatum differs from all other species of the genus by a sorediate thallus and the production of confluentic acid. It is the sister species to I. afromontanum in our phylogenetic analyses. The discovery of the new species supports the high value of these forests for biodiversity action plans. Phylogenetic analyses also place Schismatomma niveum in the Arthoniaceae and the new genus Snippocia is described to accommodate it. The genus Leprantha is resurrected for its type species ( L. cinereopruinosa ). A lectotype is designated for Arthonia pruinosella .

The phylogenetic position of ConiArthonia and the transfer of Cryptothecia miniata to Myriostigma (Arthoniaceae, lichenized ascomycetes)
Phytotaxa, 2015Co-Authors: André Aptroot, Martin Grube, Damien Ertz, Jeanne Dos Reis Silva, Marcela Eugenia Da Silva CáceresAbstract:Two lichen species with bright orange and pink colours are described. ConiArthonia megaspora from NE Brazil, with relative large, hyaline ascospores that are becoming violet in tap water after release. The phylogenetic position of ConiArthonia is for the first time assessed, based on Brazilian specimens, and Arthonia eos and A. kermesina are combined into this genus. Fertile material of Cryptothecia miniata is for the first time described from Brazil and Costa Rica. A phylogenetic analysis including the epitype places it close to Myriostigma candidum in the recently resurrected genus Myriostigma . The genera Stirtonia and Cryptothecia in their current sense are shown to be both polyphyletic.
