Cupulomyces, A New Genus of Laboulbeniales (Asomycetes) Based on Stigmatomyces Lasiochili

A new genus of Laboulbeniales, Cupulomyces, is described. Its type species, C. lasiochili, is based on Stigmatomyces lasiochili, originally described by Roland Thaxter in I 917. This taxon subsequently has been classified in two other genera, Hesperomyces and Acompsomyces. Structure and development of the thallus of C. lasiochili are described and illustrated with photographs and line drawings. Distinctive features of the receptacle, appendage, and perithecium warrant recognition of a new genus
