Peyronelia Cif. & Gonz. Frag., Boln Real Soc. Españ. Hist. Nat., Biologica 27: 333 (1927).

Index Fungorum number: IF 9281; Facesoffungi number: FoF 08105, 4 morphological species (Species Fungorum 2022), no molecular data available.

Saprobic or pathogenic on host. Sexual morph: Unknown. Asexual morph: Mycelium black, cespitose, loose, wooly; sterile hyphae creeping, septate, olive, single or sparingly branched, lacking conidiophores or undifferentiated, slightly thickened near the base of the first conidium; as long as the conidia are connected to the middle. Conidia verruculose, reddish brown to black, mostly 25 in a chain, fusoid, 310-septate, easily separating at a narrow isthmus (adapted from Ciferri and González 1927).

 Type species: Peyronelia sirodesmioides Cif. & Gonz. Frag.

Notes: Peyronelia is characterised by black, loose, wooly mycelium, lacking conidiophores with verruculose, reddish brown conidia. Peyronelia resembles Glyphium in having conidia that develop in same manner but the conidia are of comparable morphology. Hyde et al. (2013) and Wijayawardene et al. (2018) placed Peyronelia in Mytilinidiaceae. Peyronelia is currently a distinct genus in Mytilinidiaceae but molecular data and fresh collections are needed to confirm this taxonomic placement.
