A new species of Tilletia, T. rostrariae Vánky & Ershad on Rostraria cristata is described and illustrated from Iran. It is compared with T. salzmannii, on the closely related Koeleria, and with the polyphagous T. bromi.

Ustilaginomycotina (Basidiomycota, Fungi) has been reclassified recently based on multiple gene sequence analyses. However, the phylogenetic placement of two yeast-like genera Malassezia and Moniliella in the subphylum remains unclear. Phylogenetic analyses using different algorithms based on the sequences of six genes, including the small subunit (18S) ribosomal DNA (rDNA), the large subunit (...

A phylogeny of the fungal phylum Basidiomycota is presented based on a survey of 160 taxa and five nuclear genes. Two genes, rpb2, and tef1, are presented in detail. The rpb2 gene is more variable than tef1 and recovers well-supported clades at shallow and deep taxonomic levels. The tef1 gene recovers some deep and ordinal-level relationships but with greater branch support from nucleotides com...

Five smut fungi viz. Microbotryum scorzonerae on Scorzonera caliculata, Sporisorium aristidae-lanuginosae on Stipagrostisplumosa, Sporisorium desertorum on Lasiurus sindicus, Sporisorium foveolati on Dichanthium foveolatum,and Sporisorium vanderystii on Hyparrhenia hirta are reported for the first time for Iranian mycobiota. Sporisorium foveolati is also probably new to Asia. Bellevalia saviczi...

Diseases threaten the structure and function of marine ecosystems and are contributing to the global decline of coral reefs. We currently lack an understanding of how climate change stressors, such as ocean acidification (OA) and warming, may simultaneously affect coral reef disease dynamics, particularly diseases threatening key reef-building organisms, for example crustose coralline algae (CC...

The order Tilletiales (Ustilaginomycetes, Basidiomycota) includes six genera (Conidiosporomyces, Erratomyces, Ingoldiomyces, Neovossia, Oberwinkleria and Tilletia) and approximately 150 species. All members of Tilletiales infect hosts in the grass family Poaceae with the exception of Erratomyces spp., which occur on hosts in the Fabaceae. Morphological features including teliospore ornamentatio...

Peanuts can be affected by the presence of pathogenic microorganisms. The fungus Thecaphora frezii (T. frezii), which belongs to taxonomic class Ustilaginomycetes, is causal agent disease known as “peanut smut”. life cycle this includes three stages, namely teliospores, basidiospores and hyphae. In hyphae stage, infection occurs in peanut plant, requires involvement some enzymes secreted fungus...
