Uleomyces Henn., Hedwigia 34: 107 (1895)

Index Fungorum number: IF 5657; Facesoffungi number: FoF 03682, 11 morphological species (Species Fungorum 2021), molecular data unavailable.

Hyperparasitic, fungicolous on leaves. Sexual morph: Ascostromata irregular effuse, in parasitic matrix, crustose, raised pulvinate, hump-shaped, tuberculate, lacking hypostroma, subglobose, semi-immersed, containing locules with individual asci, lacking pseudoparaphyses, stromata context dark red, rounded. Asci 8-spored, bitunicate, sub ellipsoid to broad clavate, sessile. Ascospores multi-seriate, conglobate, oblong-clavate to subperiform, muriform, multi-septate, sometimes constricted at the septa, brown to dark red. Asexual morph: Undetermined (Adapted from Hennings 1895)


Type species: Uleomyces parasiticus Henn.


Notes: Uleomyces was introduced by Hennings (1895) with U. parasiticus as type species. Uleomyces was previously accommodated in Hypocreaceae. A new family Uleomycetaceae was introduced for Uleomyces but this was invalid. Uleomyces was later placed in Cookellaceae by von Arx & Müller (1975) based on characters of ascostroma, asci and ascospores. This placement was accepted by several authors (Barr 1997; Lumbsch and Huhndorf 2010). Uleomyces is characterized by irregular effuse ascostromata, hump-shaped, tuberculate, lacking pseudoparaphyses, and muriform, multi-septate, brown to dark red ascospores. Boonmee et al. (2017) accepted Uleomyces in Myriangiaceae based on characters of ascostromata and ascospores.
