Vujanovic, Vladimir, Gérard Mailloux, Chantal Hamel & Marc St-Arnaud. Impudentia crioceris, a new genus and species of dematiaceous hyphomycetes on two Crioceris insects in Québec, Canada. Mycotaxon 88: 233 - 238. 2003.

ABSTRACT: Impudentia crioceris gen. et sp. nov., a new dematiaceous hyphomycetous fungus (mitosporic fungi) is described and illustrated. It occurs on two Crioceris species: Crioceris asparagi and C. duodecimpunctata (Coleoptera : Chrysomelidae), insects from asparagus fields in Québec, Canada. It is unique in producing two types of dark, aseptate macroconidia with an elongated germ slit holoblastically from dark brown, cylindrical conidiogenous cells or from undifferentiated cells on brownish hyphae or stromata. Impudentia is compared with Arthrinium, Gilmaniella, Mamaria, Chalara, Wardomyces and Yinmingella.
