elaphomyces species elaphomycetaceae Eurotiales from bartlett experimental forest new hampshire usa
IMA Fungus. 8(1): 49-63., 2017Co-Authors: Michael A Castellano, Ryan B StephensAbstract:We describe five new species of Elaphomyces from Bartlett Experimental Forest, New Hampshire, USA (E. americanus, E. bartlettii, E. macrosporus, E. oreoides, and E. remickii) and revise the description of a sixth previously published species (E. verruculosus). Of the five new species, E. bartlettiii and E. remickii are only known from New Hampshire whereas E. americanus, E. macrosporus, and E. oreoides are widely distributed in eastern North America. Elaphomyces verruculosus is the most widespread and abundant Elaphomyces species in eastern North America with a distribution extending from eastern Canada south to northeastern Mexico. All six Elaphomyces species are putatively associated with Tsuga canadensis, a tree species in regional decline. For five of the six Elaphomyces species, we report partially consumed ascomata or rodent fecal samples containing spores, indicating that small mammals play a key role in dispersing these Elaphomyces species and that the Elaphomyces are an important part of the small mammals’ diet.

new species of elaphomyces elaphomycetaceae Eurotiales ascomycota from tropical rainforests of cameroon and guyana
IMA Fungus, 2016Co-Authors: Michael A Castellano, Bryn T M Dentinger, Olivier Sene, Todd F Elliott, Camille Truong, Terry W. HenkelAbstract:The sequestrate false truffles Elaphomyces favosus, E. iuppitercellus, and E. labyrinthinus spp. nov. are described as new to science from the Dja Biosphere Reserve, Cameroon. Elaphomyces adamizans sp. nov. is described as new from the Pakaraima Mountains of Guyana. The Cameroonian species are the first Elaphomyces taxa to be formally described from Africa, occurring in lowland Guineo-Congolian tropical rainforests dominated by the ectomycorrhizal (ECM) canopy tree Gilbertiodendron dewevrei (Fabaceae subfam. Caesalpinioideae). The Guyanese species is the third to be discovered in lowland tropical South America, occurring in forests dominated by the ECM trees Pakaraimaea dipterocarpacea (Dipterocarpaceae) and Dicymbe jenmanii (Fabaceae subfam. Caesalpinioideae). Macromorphological, micromorphological, habitat, and DNA sequence data are provided for each new species. Molecular and morphological data place these fungi in Elaphomycetaceae (Eurotiales, Ascomycota). Unique morphological features are congruent with molecular delimitation of each of the new species based on a phylogenetic analysis of the rDNA ITS and 28S loci across the Elaphomycetaceae. The phylogenetic analysis also suggests that a common ancestor is shared between some Elaphomyces species from Africa and South America, and that species of the stalked, volvate genus Pseudotulostoma may be nested in Elaphomyces.

Miller, Matthew E Smith, Catherine M AimeAbstract:Elaphomyces compleximurus sp. nov. and E. digitatus sp. nov. are described from the Pakaraima Mountains of Guyana. Macromorphological, micro- morphological, habitat and DNA sequence data are provided for each new species. This is the first report of Elaphomyces ascomata associated with ectomycor- rhizal members of the Fabaceae and also for the genus from the lowland South American tropics.

The mycorrhizal status of Pseudotulostoma volvata (Elaphomycetaceae, Eurotiales, Ascomycota)
Mycorrhiza, 2006Co-Authors: Terry W. Henkel, Timothy Y. James, Steven L. Miller, M. Catherine Aime, Orson K. MillerAbstract:Pseudotulostoma volvata (O. K. Mill. and T. W. Henkel) is a morphologically unusual member of the otherwise hypogeous Elaphomycetaceae due to its epigeous habit and exposed gleba borne on an elevated stalk at maturity. Field observations in Guyana indicated that P. volvata was restricted to rain forests dominated by ectomycorrhizal (EM) Dicymbe corymbosa (Caesalpiniaceae), suggesting an EM nutritional mode for the fungus. In this paper, we confirm the EM status of P. volvata with a combination of morphological, molecular, and mycosociological data. The EM status for P. volvata corroborates its placement in the ectotrophic Elaphomycetaceae.

A taxonomic and ecological overview of cheese fungi
International Journal of Food Microbiology, 2012Co-Authors: Jeanne Ropars, Sandrine Lacoste, Corinne Cruaud, Joëlle DupontAbstract:Abstract Cheese is made from milk by a succession of microbes (bacteria, yeasts and fungi) that determine the consistency and flavor of the cheese. Apart from the emblematic species, Penicillium camemberti and Penicillium roqueforti , cheese fungi are not well known. Here we present a taxonomic and phylogenetic overview of the most important filamentous cheese Ascomycota based on 133 isolates provided by the producers of cheese and cheese starter cultures and 97 isolates from culture collections. We checked the congruence of different gene genealogies to circumscribe cheese species and our results allow us to propose molecular targets for their identification. To study their phylogenetic affiliation, we used LSU rDNA and showed that cheese fungi are found in two classes, the Eurotiomycetes with Penicillium species (Eurotiales) and Sporendonema casei / Sphaerosporium equinum (Onygenales), and the Sordariomycetes with Scopulariopsis species (Microascales) and Fusarium domesticum (Hypocreales). Some of these fungi, such as, P. camemberti , F. domesticum , Scopulariopsis flava and S. casei , are only known from cheeses and are probably adapted to this particular habitat, which is extremely rich in protein and fat. Other cheese fungi are ubiquitous, such as, P. roqueforti , Scopulariopsis candida and Scopulariopsis fusca .
