Polylobatispora setulosa sp. nov. is described and illustrated from submerged mixed leaf litter samples collected at streams in Ilhabela, São Paulo state, Brazil. The fungus is distinct in having setulae at the tip of the conidial lobes. Acumispora verruculosa, isolated from identical substrate and characterized by the presence of fusiform, acuminate, rostrate, verrucose, 2-septate, hyaline to greenish conidia, is recorded for the third time from the Americas. They are compared with morphologically similar species and identification keys are provided. © 2015. Source

Ellisembia mercadoi sp. nov., collected on rachides of dead leaves of Sabal palmetto in southwestern Florida, U.S.A., is described and illustrated. The fungus is characterized by cylindrical, determinate conidiogenous cells and verruculose, subfusiform to narrowly obclavate or obclavate-rostrate, 7-16 distoseptate conidia often with remnants of an apical mucilaginous sheath. Similarities and differences with morphologically related species within the genus are discussed. Berkleasmium leonense, Ceratosporella basibicellularia, Hermatomyces tucumanensis, Monodictys capensis, and Selenosporella perramosa are newly recorded from the U.S.A. © 2013. Mycotaxon, Ltd. Source

Clathrosporium retortum sp. nov., collected on submerged mixed leaf litter samples at Ilha do Cardoso State Park, Sao Paulo state, Brazil, is described based on morphological and molecular data. The fungus is characterized by forming whitish, dense, subglobose to irregular propagules, hyaline to subhyaline when young, subhyaline to dark brown at maturity, that are formed by densely interwoven conidial filaments with each conidial cell repeatedly branching bilaterally or occasionally unilaterally. Phylogenetic analyses using partial LSU nrDNA sequence data suggest that C. retortum belongs in the Sordari-omycetes (Ascomycota) where it forms a well-supported clade with Clohesia corticola in the Sordariomycetidae, but its ordinal or familial placement remains unresolved. Its phylogenetic placement confirms the polyphyletic nature of aeroaquatic fungi like Clathrosporium, as it was distantly related to one available sequence in GenBank named as C. intricatum, the type species, which is phylogenetically related to the Helotiales (Leotiomycetes). However, due to lack of authenticity of the identity of this sequence with the type specimen of C. intricatum, a broad concept of Clathrosporium is tentatively adopted here to accommodate the present fungus instead of introducing a new genus. Beverwykella clathrata, Helicoon septatissi-mum and Peyronelina glomerulata are recorded for the first time from Brazil. Cancellidium applanatum and Candelabrum brocchiatum are new records for the state of Sao Paulo. © 2015 Magnolia Press. Source

A set of historical specimens collected by the American mycologist Charles Leonard Smith in southeastern Nicaragua during 1896 and currently deposited at the Herbarium of the Charles University in Prague (PRC) was examined for the presence of microfungi. Despite the age of the specimens, twenty-two taxa were identified, seventeen of them to species level and other five to generic level. All of them are recorded for the first time from Nicaragua. Cryptophiale cf. kakombensis and Sporoschisma juvenile were found associated with their putative teleomorphic states. Historical facts surrounding the expedition source of these samples and bibliographical data about Smith are also given. © 2016 Adac. Tous droits réservés. Source
