Index Fungorum number: MB 834905; Facesoffungi number: FoF14495
Etymology: Named after the colour of the stromata in nature.
Description: Stroma solitary, white at the tip when young (immature) to purple, especially around the ostioles, cylindrical to clavate with tapering end, flexuous. Hosts are Lepidoptera larva or pupa underground. Perithecia immersed to semi-immersed,
ovoid, oblique in arrangement. Asci cylindrical, 8-spored; asco- spores hyaline, filiform, whole, septate, not breaking into part- spores. Asexual morph lecanicillium-like.
Type species: Purpureomyces khaoyaiensis (Hywel-Jones) Luangsa-ard, Samson & Thanakitpipattana.
Notes: – Three species are recognised in this genus that all produce purple stromata and obliquely immersed perithecia. Phylogenetically, it is closely related to Marquandomyces and Papiliomyces. The asexual morph in Marquandomyces is paecilomyces-like and in Purpureomyces it is lecanicillium-like. There is no record of the asexual morph in Papiliomyces
