Stereopsis (fungus)

Stereopsis is a genus of fungi in the family Stereopsidaceae. It was formerly placed in the family Meruliaceae in the order Polyporales but was found to belong in its own order along with the genus Clavulicium. The genus was circumscribed by English mycologist Derek Reid in 1965. It contains species that form funnel shaped basidiocarps as well as the corticioid species Stereopsis globosa which was formerly considered a species of Clavulicium. The species Stereopsis humphreyi and Stereopsis vitellina were found to belong in the Agaricales and Atheliales respectively in a molecular phylogenetics study, and because of this do not belong in Stereopsis, but they have not yet been transferred to their own genera.
