Boerlagiomyces
Boerlagiomyces Butzin.
IndexFungorum number: IF 607; Facesoffunginumber: FoF 00209
Saprobic on decaying wood in freshwater or terrestrial habitats. Sexual morph: Ascomata superficial, seated on a subiculum, globose, scattered, with flexuous, hairy, black, velvety, septate setae, surrounded by black mycelium. Peridium composed of carbonaceous, multi-layered walls. Hamathecium composed of filiform, hyaline pseudoparaphyses. Asci 8-spored, bitunicate, cylindric-clavate, narrowing towards base, short-pedicellate or apedicellate, apically rounded. Ascospores 2–3-seriate, cylindric-fusoid, gently curved, obtuse at both ends, muriform, multiseptate, not constricted at septa, hyaline, smooth-walled (adapted from Penzig and Saccardo 1904). Asexual morph: Unknown.
Type species: Boerlagiomyces velutinus (Penz. & Sacc.) Butzin
Notes: Boerlagiomyces is characterized by superficial ascomata with sparse, hyphal appendages and muriform ascospores (Boonmee et al. 2014). Boerlagiomyces was placed in Tubeufiaceae based on a reference sequence of B. macrosporus V.G. Rao & Varghese (Doilom et al. 2017) and accepted by Lu et al. (2018). The type species B. velutinus has eight ascospores (Boonmee et al. 2014), while three freshwater species, viz. B. grandisporus S.J. Stanley & K.D. Hyde, B. lacunosisporus (K.D. Hyde) S.J. Stanley & K.D. Hyde and B. websteri Shearer & J.L. Crane, mostly have two ascospores (Hyde 1992; Shearer and Crane 1995; Stanley and Hyde 1997). The sequence data of above freshwater species are needed to confirm their phylogenetic placement.
