Neogloeosporidina W.J. Li, Camporesi & K.D. Hyde, gen. nov.
Index Fungorum number: IF557154, Facesoffungi number: FoF 07519
Etymology: Named after its morphology similar with Gloeosporidina.
Leotiomycetes, Leotiomycetidae, Medeolariales, Dermateaceae
Saprobic on plant host in terrestrial habit. Sexual morph: undetermined. Asexual morph: Conidiomata brown, eustromatic, pycnidial, scattered, rarely gregarious, subepidermal or subperidermal in origin, immersed to partly erumpent, globose to subglobose, unilocular, thick-walled, smooth, glabrous. Ostiole absent, dehiscing by an irregular rupture in the apical region, then becoming wide open. Conidiomatal wall composed of brown, thick-walled cells of compressed textura angularis. Conidiophores mostly reduced to conidiogenous cells, occasionally present, short, cylindrical, septate and branched at base, formed from inner layers of conidiomata. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical, usually integrated, determinate, smooth-walled. Conidia hyaline, ellipsoid to ventricose, often with a blunt apiculus, unicellular, thick- and smooth -walled.
Type species: Neogloeosporidina pruni W.J. Li, Camporesi & K.D. Hyde, sp. nov.
Notes: Neogloeosporidina pruni was collected from Italy. The sequence was obtained directly from conidiomata. Multi-locus phylogeny reveals N. pruni clusters in a well-supported branch basal to Dermea and Corniculariella. Neogloeosporidina pruni shares similar characters with Gloeosporidina in having elliptical conidia, and enteroblastic, phialidic, integrated conidiogenous cells, but it can be distinguished by its eustromatic, pycnidial conidiomata. Combining both morphology and phylogeny, Neogloeosporidina is introduced as a new genus.
