Escovopsis aspergilloides is described as a new species of hyphomycete
isolated from attine ant nests originating in Trinidad. The new speci
es differs from the type of this previously monotypic genus, E. weberi
, primarily by its globose, rather than clavate, phialide-bearing vesi
cles. The history of both of these species in the ant-nest fungus lite
rature is reviewed.
