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

Index Fungorum Number: IF558798 ; Facesoffungi Number: FOF10490

Type species:— Heveicola xishuangbannaensis R.F. Xu, K.D. Hyde & 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 macronematous, synnematous, erect, brown to dark brown, cylindrical, septate. Conidia catenate, ellipsoidal or oblong, 0–4 to multi-septate, slightly constricted at median septum, rounded at both ends, formed in acropetal chains, often with a dark brown band at the septa, initially hyaline, pale brown to brown.

Notes:— Asexual morphs of all genera in Wiesneriomycetaceae have conidia produced in acropetal chains. The new genus also has chains of septate conidia, fitting the concept of Wiesneriomycetaceae . Heveicola differs morphologically from other members in Wiesneriomycetaceae (see key below).
