Volutella (fungus) explained

Volutella is a genus of fungi belonging to the family Nectriaceae.^[1]

The fungal genus was established by Fries (1832) with Volutella ciliata (Alb. & Schwein.) Fr. as the type species. It had about 47 species in 2011, however, many species were later revised and transferred to other genera such as Calonectria, Coccinonectria, Lectera, Koorchaloma, Pseudonectria and Volutellonectria^[2] and only 11 species have sequence data in GenBank. Gräfenhan et al. (2011) then revised the genus and accepted three species viz. Volutella ciliata, Volutella consors and Volutella citrinella into Volutella.^[2] Later, seven additional species were introduced in the genus. ^{[3] [4] [5] [6] [7] [8]}

The genus is characterized by discoid sporodochia (or synnemata) with marginal setae, sparingly branched to verticillate conidiophores, compact and phialidic conidiogenous cells, and 1-celled, ovoid to oblong conidia. asexond asexual morph is present in some species with two or more whorls of conidiogenous cells.^{[2] [9] [5] [6]}
