Dimorphomyces Thaxt.

Index Fungorum number: IF 1590; Mycobank number: MB 1590

Notes – Dioecious genus consisting of 29 recognized species, of which the most recently described is D. carolinae (Rossi 2010). The female thallus consists of a row of small cells bordered below by an extension of the basal cell; these cells produce from their upper side either perithecia or secondary appendages. The male thallus is much smaller, being composed of a few celled receptacle, compound flask-shaped antheridia and a simple appendage. The majority of the hosts of Dimorphomyces are rove beetles (Coleoptera, Staphylinidae), but a few species are found on other insect families (viz. Carabidae and Tenebrionidae), one on ants and two on mites. No DNA sequence is available for any of the species in Dimorphomyces.
