Loculosulcatispora
Loculosulcatispora G.C. Ren & K.D. Hyde, in Ren et al., Phytotaxa 475(2): 70 (2020).
Index Fungorum number: IF 557580; Facesoffungi number: FoF 07977, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic on decaying wood. Sexual morph: see Wang et al. (2023). 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, one celled, smooth-walled, guttulate (adapted from Ren et al. 2020).
Type species: Loculosulcatispora thailandica G.C. Ren & K.D. Hyde
Notes: Loculosulcatispora is characterised by solitary, scattered, immersed or semi-immersed conidiomata, hyaline, doliiform to cylindrical, aseptate conidiogenous cells and hyaline, oblong, one-celled, smooth-walled conidia. Loculosulcatispora resembles Botryosphaeria, Ciliosporella, Cornutispora, Melanops, Neodermea, Neodidymelliopsis, Neofusicoccum, Phacidium and Sakireeta in having multi-locular pycnidia but Loculosulcatispora differs by its conidial features. In the phylogenetic analysis of Ren et al. (2020) based on SSU, LSU, ITS, TEF-1 and RPB2, Loculosulcatispora grouped in Sulcatisporaceae with low statistical support. Loculosulcatispora resembles members of Sulcatisporaceae in having scattered, immersed, subglobose or conical, black pycnidia with a central ostiole but differs in having hyaline, aseptate, oblong, guttulate conidia (Phookamsak et al. 2019, Ren et al. 2020). Magnicamarosporium, Sulcatispora and Neobambusicola have muriform dark brown conidia, ellipsoid, yellowish brown, multiseptateconidia, and hyaline fusoid-ellipsoid, finely guttulate, uniseptate conidia, respectively (Crous et al. 2014, Tanaka et al. 2015, Phookamsak et al. 2019, Ren et al. 2020). Loculosulcatispora is morphologically and phylogenetically a well-distinct genus in Sulcatisporaceae. Molecular markers available for Loculosulcatispora are ITS, LSU, SSU, RPB2 and TEF-1.
