Cycasicola

Cycasicola Wanas., E.B.G. Jones & K.D. Hyde, in Wanasinghe et al., Fungal Diversity: 10.1007/s13225-018-0395-7, [161] (2018).

 Index Fungorum number: IF 554213; Facesoffungi number: FoF 04052, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.

Saprobic on Cycas sp. Sexual morph: Unknown. Asexual morph: Coelomycetous. Conidiomata pycnidial, solitary, gregarious or confluence, immersed, unilocular, globose, dark brown, ostiolate. Ostiole papillate. Peridium composed of thick-walled cells of textura angularis, brown. Conidiophores reduced to conidiogenous cells. Conidiogenous cells phialidic, ampulliform, hyaline, smooth-walled. Conidia fusiform to cylindrical, guttulate, continuous, straight or slightly curved, aseptate, obtuse at apex and base, sometimes slightly truncate at base, hyaline or pale brown, smooth-walled (adapted from Wanasinghe et al. 2018).

Type species: Cycasicola goaensis Wanas., E.B.G. Jones & K.D. Hyde

Notes: Cycasicola is unique in having globose, unilocular conidiomata with papillate ostiole, phialidic, ampulliform, hyaline conidiogenous cells and fusiform to cylindrical, continuous, hyaline to pale brown, aseptate, guttulate conidia. Molecular markers available for Cycasicola are ITS, LSU, SSU, TEF-1 and RPB2.
