Baudoinia
Baudoinia J.A. Scott & Unter., in Scott et al., Mycologia 99(4): 594 (2007).
Index Fungorum number: IF 510726; Facesoffungi number: FoF 06999, 5 morphological species (Species Fungorum 2022), 5 species with molecular data.
Extremophilic saprotroph on host substrate. Sexual morph: Unknown. Asexual morph: Mycelium black, effused, velvety to crust-like. Vegetative hyphae dark brown, thick-walled, often moniliform. Distinctive conidiophores lacking. Conidiogenous cells integrated within vegetative hyphae. Conidia dry, nonseptate or uniseptate at the median, thick-walled, globose to barrel-shaped, brown to black, typically with coarse surface ornamentation, dehiscencing by schizolysis. Ramoconidia absent. Colonies on MLA media usually slow growing, darkly pigmented (adapted from Scott et al. 2007).
Type species: Baudoinia compniacensis (Richon) J.A. Scott & Unter.
Notes: Baudoinia is characterised by schizolytic fragmentation of unspecialized hyphae into conidia. Baudoinia occurs in the outdoors in association with low, intermittent levels of ethanol vapor (Scott et al. 2007). Scott et al. (2016) showed the placement of Baudoinia in Teratosphaeriaceae based on morphological analyses. Scott et al. (2016) showed the placement of Baudoinia in Teratosphaeriaceae based on multigene analyses of nucITS rRNA (ITS1-5.8S-ITS2) and partial nucLSU rRNA, beta-tubulin (TUB) and elongation factor 1-alpha (TEF1) gene sequences. Scott et al. (2016) reported that Baudoinia is a monophyletic lineage within Teratosphaeriaceae (Capnodiales) and consists five strongly supported, geographically patterned lineages with four new species namely Baudoinia antilliensis, B. caledoniensis, B. orientalis and B. panamericana. Molecular markers available for Baudoinia are ITS, LSU, SSU, BTUB and TEF-1.
