Brunneomycosphaerella Dissanayake., J.K. Liu & K.D.Hyde.
Index Fungorum number: IF551058, Facesoffungi number: FoF00565
Etymology: Brunneomycosphaerella, in reference to the brown spores of a mycospherella-like species.
Type species: Brunneomycosphaerella laburni Dissanayake., J. K. Liu & K. D. Hyde

Saprobic on dead branches. Sexual morph Ascostromata solitary, scattered or gregarious, immersed to erumpent, dark brown to black, uni- to bi-loculate, globose to sub-globose. Peridium comprising brown to black-walled cells of textura angularis. Hamathecium comprising septate, hyaline pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, elongate, cylindrical to slightly clavate at the base, pedicellate, rounded at apex with a canal-like structure, with an ocular chamber. Ascospores multi-seriate, dark yellow to brown, 1-septate, deeply constricted at the septum, ellipsoidal with broadly rounded ends, with small and large guttules, smooth-walled, lacking a sheath. Asexual morph Undetermined.

Notes: Phylogenetic analysis of combined SSU and LSU gene sequence data (Fig. 1) place Brunneomycosphaerella in Clade A in an unresolved group in Capnodiales with rock inhabiting fungi (Schoch et al. 2009; Hyde et al. 2013). We therefore introduce a new genus and place it in Capnodiales, family incertae sedis.

Fig. 1 Phylogram generated from Maximum likelihood (RAxML) analysis based on combined LSU and SSU gene region sequence data of related taxa in Capnodiales. Maximum likelihood bootstrap support values greater than 50 % are indicated above or below the nodes, and branches with Bayesian posterior probabilities greater than 0.95 are given in bold. The ex-types (ex-epitypes and reference strains) are in bold; the new isolates are in blue. The tree is rooted with Botryosphae dothidea AFTOL ID-946.
