Loculosulcatispora G.C. Ren & K.D. Hyde, Phytotaxa 475 (2) 067-078 (2020)

Index Fungorum number: IF 557580, Facesoffungi number: FoF 07977

Etymology: From the combination of two words ‘loculo’ and ‘sulcatispora’ referring to loculate conidiomata in Sulcatisporaceae


Saprobic on decaying wood. Sexual morph: Undetermined. Asexual morph: Conidiomata solitary, scattered, immersed or semi-immersed, conical, ostiolate, black, multilocular. Ostioles single or multiple, central, short. Peridium outer layer comprising dark pigmented cells of textura angularis, inner layer comprising hyaline cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells arising from the stratum, hyaline, doliiform to cylindrical, aseptate, unbranched, holoblastic, determinate, smooth-walled. Conidia hyaline, oblong, onecelled, smooth-walled, guttulate.


Type species:  Loculosulcatispora thailandica G.C. Ren & K.D. Hyde


Notes:  Compared our new genus with the species of hyaline coelomycetes in Li et al. (2020). Loculosulcatispora is similar to Botryosphaeria, Ciliosporella, Cornutispora, Melanops, Neodermea, Neodidymelliopsis, Neofusicoccum, Phacidium and Sakireeta in having multi-locular pycnidia. However, Loculosulcatispora differs by its conidial characteristics. In the phylogenetic analysis Loculosulcatispora clusters in Sulcatisporaceae with Magnicamarosporium, Neobambusicola and Sulcatispora and is similar to these genera in having scattered, immersed, subglobose or conical, black pycnidia with a central ostiole (Crous et al. 2014, Tanaka et al. 2015, Phookamsak et al. 2019). However, Loculosulcatispora differs in having hyaline, aseptate, oblong, guttulate conidia. Magnicamarosporium species have muriform and dark brown conidia. Sulcatispora species have ellipsoid, yellowish brown, multi-septate conidia with striate ornamentation. Neobambusicola species have hyaline fusoid-ellipsoid, finely guttulate, 1-septate conidia that are constricted at the septum (Crous et al. 2014, Tanaka et al. 2015, Phookamsak et al. 2019). Loculosulcatispora is phylogenetically well-separated from other genera in this family. Therefore, we introduce Loculosulcatispora as a new genus of Sulcatisporaceae.
