Towyspora Wanasinghe, E.B.G. Jones & K.D. Hyde, in Li et al., Fungal Diversity 78: [32] (2016)

Dothideomycetes, Pleosporomycetidae, Pleosporales, Lentitheciaceae


Saprobic on the host plant. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, eustromatic, scattered to gregarious or confluent, semi-immersed to erumpent, unilocular or multilocular, ostiolate, glabrous. Ostiole short, circular, centrally located. Conidiomatal wall composed of thick-walled, dark brown to hyaline cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline, enteroblastic, phialidic, lageniform to subcylindrical, thick- and smooth-walled. Conidia hyaline, cylindrical, 01-septate, guttulate, smooth-walled.


Type species: Towyspora aestuari Wanasinghe, E.B.G. Jones & K.D. Hyde, in Li et al., Fungal Diversity 78: [35] (2016)


Notes: Towyspora is monotypic. This genus is similar to Chaetosphaeronema in having phialidic conidiogenous cells and cylindrical, 01-septate conidia. However, Chaetosphaeronema has pycnidial conidiomata with periphyses, whereas Towyspora has eustromatic conidiomata lacking periphyses. Phylogenetically, Towyspora was placed in Lentitheciaceae, while Chaetosphaeronema was placed in Phaeosphaeriaceae.


Distribution: UK.
