Galzinia oberwinkleri sp. nov.: one of the three known very rare Galzinia species with bifurcate basidiospores

摘要

A new species of Galzinia (Basidiomycota, Corticiaceae s. str.) with bifurcate basidiospores is described. Galzinia oberwinkleri was found on the roots of a young orchid in a mountain rain forest in Ecuador. It is characterized by very tiny resupinate, mucous-gelatinous, and watery basidiomata with very large basidia and basidiospores that are bifurcate. A key for corticioid species with bifurcate basidiospores and illustrations of their microanatomy are presented.
