Bryoclavula is a small genus of lichen-forming fungi of uncertain familial placement in the order Cantharellales.[1] It comprises two species of bryophilous lichens (lichens that grows on bryophytes). The genus was circumscribed by Hiroshi Masumoto and Yousuke Degawa in 2020, with B. phycophila assigned as the type, and at the time, only species. An additional species, discovered in east Texas, USA, was added to the genus in 2024.[2]
Bryoclavula was established in 2020 by Hiroshi Masumoto and Yousuke Degawa, with B. phycophila designated as the type, and at the time, only species.[3] The generic name combines "bryo" (Greek, referring to bryophytes, the substrate on which it grows) and "clavula" (Latin, referring to the small clavarioid or club-shaped fruiting bodies).[3]
Phylogenetic analyses of nuclear ribosomal RNA gene (nrLSU) sequences place Bryoclavula in a distinct lineage within the Cantharellales, in what has been referred to as the "CHS assemblage" (comprising members of Clavulinaceae, Hydnaceae, and Sistotremataceae). The genus forms a moderately supported monophyletic group with Minimedusa and certain Sistotrema species, though exact relationships among these lineages remain unresolved.[3]
Bryoclavula is distinguished from the morphologically similar genus Multiclavula (also in Cantharellales) by both molecular phylogeny and the structure of its lichenized thallus, which in Bryoclavula is undifferentiated and does not form the globular or bulbil-like structures characteristic of Multiclavula.[3]
