... As indicated in our previous studies and those of numerous other authors (Wu and Zhuang 2005;Delgado 2011;Heredia et al. 2014;Qu et al. 2014;Prasher and Verma 2015;Hernández-Restrepo et al. 2017;Kirschner et al. 2017), saprobic dematiaceous hyphomycetes are observed with high density and species diversity on rotting woody plant material, which indicates important roles in nutrient recycling. The ecological roles of these fungi in nutrient cycling have, however, hitherto not been quantiied. ...
Spadicoides obovata occurring on the decaying leaf litter in Berinag forest, Pithoragarh, Uttarakhand, India is described and illustrated. This rare newly recorded fungal species from India is characterized by single, straight or slightly curved, obovoid conidia with usually up to 2 septa appearing as thick dark bands, borne over the simple, erect, and proliferating conidiophores. Apart from it, the conidiogenous cells generally formed by terminal or subterminal cells, with several minute pores serve as another conspicuous feature. Notes, illustrations, descriptions based on natural substrates and comparisons with other related species based on morphological traits are provided in this paper. This represents the first report of S. obovata from India.

In this paper, the authors present modern microscopical studies for 28 type specimens of Russula species described by C.H. Peck, thereby completing the revision of all 44 Russula taxa described by this author and for which type specimens were available. Our results suggest that with eventual exception of R. granulata var. lepiotoides (a likely synonym of the type variety) and R. magnifica (a likely synonym of R. polyphylla), all other Russulas described by Peck correspond to well-defined North American taxa. Having been described more than one century ago, Peck’s names represent the majority of the earliest described North American Russula species and our type revisions are therefore important both for nomenclatural aspects, as well as typification and identification purposes. All studied taxa are illustrated in detail and accompanied by notes including a short recapitulation of previous type revisions, as well as our own re-evalutation of their systematic position as a result of this study.

The taxonomic status and phylogenetic placement of Sporidesmium pachyanthicola in Capnodiales (Dothideomycetes) are revisited based on a specimen collected on the petiole of a dead leaf of Sabal palmetto in south Florida, U.S.A. New evidence inferred from phylogenetic analyses of nuclear ribosomal DNA sequence data together with a broad taxon sampling at family level suggest that the fungus is a member of Extremaceae and therefore its previous placement within the broadly defined Teratosphaeriaceae was not supported. A new genus Castanedospora is introduced to accommodate this species on the basis of its distinct morphology and phylogenetic position distant from Sporidesmiaceae sensu stricto in Sordariomycetes. The holotype material from Cuba was found to be exhausted and the Florida specimen, which agrees well with the original description, is selected as epitype. The fungus produced considerably long cylindrical to narrowly obclavate conidia in culture strongly resembling those of Sporidesmajora pennsylvaniensis, another sporidesmium-like, capnodiaceous anamorph. However, phylogenetic analyses show that they are not congeneric and the latter belongs to the family Phaeothecoidiellaceae.
... The southern tip of the Florida peninsula, with its humid subtropical climate, extensive habitat diversity, and distinctive vegetation that includes a high percentage of tropical plant species, is likely to harbor a rich but still under-explored mycobiota. In the course of our continuing studies on saprobic microfungi occurring in the area, particularly those hyphomycetous anamorphs associated with dead plant debris (Delgado 2008a(Delgado , b, 2009(Delgado , 2010, a distinct and unusual species of Ellisembia Subram. was found. ...
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.
Over the past three decades, a wealth of studies has shown that palm trees (Arecaceae) are a diverse habitat with intense fungal colonisation, making them an important substratum to explore fungal diversity. Palm trees are perennial, monocotyledonous plants mainly restricted to the tropics that include economically important crops and highly valued ornamental plants worldwide. The extensive research conducted in Southeast Asia and Australasia indicates that palm fungi are undoubtedly a taxonomically diverse assemblage from which a remarkable number of new species is continuously being reported. Despite this wealth of data, no recent comprehensive review on palm fungi exists to date. In this regard, we present here a historical account and discussion of the research on the palm fungi to reflect on their importance as a diverse and understudied assemblage. The taxonomic structure of palm fungi is also outlined, along with comments on the need for further studies to place them within modern DNA sequence-based classifications. Palm trees can be considered model plants for studying fungal biodiversity and, therefore, the key role of palm fungi in biodiversity surveys is discussed. The close association and intrinsic relationship between palm hosts and palm fungi, coupled with a high fungal diversity, suggest that the diversity of palm fungi is still far from being fully understood. The figures suggested in the literature for the diversity of palm fungi have been revisited and updated here. As a result, it is estimated that there are about 76,000 species of palm fungi worldwide, of which more than 2500 are currently known. This review emphasises that research on palm fungi may provide answers to a number of current fungal biodiversity challenges.
In this study, Pararhexoacrodictys gen. nov., with Pa. catolensis as the type species is described and compared with morphologically similar Acrodictys-like genera. The new genus is phenotypically similar to both Rhexoacrodictys and Pseudoacrodictys but separated by other morphological characters. Pa. minima sp. nov. and two combinations, Pa. balansae and Pa. magnicornuata, are introduced, and new records of Pseudoacrodictys and Shrungabeeja are also registered for South America and the Neotropics.
