Pedrocrousiella Rajeshkumar, U. Braun & J.Z. Groenew., gen. nov.
MyycoBank number: MB 838146; Index Fungorum number: IF 838146; Facesoffungi number: FoF 11192;
Etymology: Named after Pedro Crous, director of the Westerdjik Fungal Biodiversity Institute and researcher who established the modern taxonomy and backbone of Mycosphaerellaceae.
Classification: Mycosphaerellaceae, Mycosphaerellales, Dothideomycetes.
Diagnosis: Pedrocrousiella is morphologically indistinguishable from Asperisporium s. lat., but it differs phylogenetically from Asperisporium s. str., determined by its type species, A. caricae, by forming a distant lineage.
Conidiomata foliicolous, sporodochial, scattered, olive brown to dark brown, erumpent. Conidiophores arising from stromata, densely fasciculate, aseptate or septate, macronematous, mononematous, simple, straight to slightly sinuous, almost smooth to verruculose-rugose, pale brown, wall thin to somewhat thickened. Conidiogenous cells integrated, terminal, or conidiophores reduced to conidiogenous cells, cylindrical (geniculation caused by sympodial proliferation not evident), polyblastic, often with numerous conidiogenous loci thickened and darkened (cicatrized). Conidia formed singly, broad ellipsoid, ovate or obclavate, 0–2-septate, wall thin, pale olivaceous to olivaceous brown, verruculose, apices obtuse, bases truncated, basal hilum barely to somewhat thickened and darkened, schizolytic.
Type species: Pedrocrousiella pongamiae (Syd. & P. Syd.) Rajeshkumar, U. Braun & J.Z. Groenew. (≡ Fusicladium pongamiae Syd. & P. Syd.).
