Heveicola R.F. Xu, K.D. Hyde & Tibpromma, gen. nov.

MycoBank number: MB 558798; Index Fungorum number: IF 558798; Facesoffungi number: FoF 10490;

Type species: Heveicola xishuangbannaensis Xu R.F & Tibpromma

Etymology: named after the host genus, Hevea

Saprobic on decaying wood, leaves and rubber latex in terrestrial habitats. Sexual morph: Undetermined. Asexual morph: Hyphomycetous. Colonies on natural substrate, mass of spores all over the surface. Conidiophores aggregated synematous, macronematous, straight or slightly flexuous, pale brown, dark brown at central, septate, unbranched. Conidiogenous cells reduce to conidia. Conidia catenate, ellipsoidal or oblong, 0–4 to multi-septate, slightly constricted at medium septum, rounded at the both end, formed in acropetal chains, often with a dark brown band at the septum, branch, initially hyaline, pale brown to brown.

Notes: Asexual morphs of all genera in Wiesneriomycetaceae have conidia produced in acropetal chains. Our new isolate also has chains of conidia, and each conidia is septate, fitting the concept of Wiesneriomycetaceae. It differs morphologically from other members in Wiesneriomycetaceae. A key to the genera in Wiesneriomycetaceae is provided.
