Pseudorobillarda M. Morelet, Bull. Soc. Sci. nat. Arch. Toulon et du Var 175: 5 (1968).
Saprobic on host plant. Sexual morph: Undetermined.. Asexual morph: Conidiomata dark brown to black, pycnidial, solitary to gregarious, immersed or semi- immersed, globose or subglobose, unilocular or multilocular, glabrous, thick-walled, ostiolate. Ostiole cylindrical, circular, centrally or laterally located. Conidiomatal wall composed of thick-walled, brown to hyaline cells of textura angularis to textura prismatica. Paraphyses hyaline, filiform, aseptate or septate, branched or unbranched. Conidiophores formed from inner layer of conidioma, reduced to conidiogenous cells or present, when present, hyaline, cylindrical, branched, smooth-walled. Conidiogenous cells hyaline, enteroblastic, phialidic, cylindrical or subcylindrical or lageniform, indeterminate, discrete or integrate. Conidia hyaline, fusiform, subcylindrical, ellipsoid, naviculate, unicellular or septate, guttulate or not, thick and smooth-walled, bearing flexous, divergent, extracellular appendages (Adapted from Li et al., 2020).
Type species: Pseudorobillarda phragmitis (Cunnell) M. Morelet
Notes: Pseudorobillarda was introduced by Morelet (1968) to accommodate P. phragmitis as type species. Pseudorobillarda accommodate species characterized by conidia with basal appendages. Species of Pseudorobillarda are mostly differentiated by presence or absence of paraphyses and conidial structures such as position, shape, length/size and septation (Nag Raj, 1993). Li et al. (2020) recently provided an account of the genus. Pseudorobillarda is a distinct genus in Pseudorobillardaceae but lacks sequence data. Fresh collections with DNA sequence data are needed to confirm the systematic position of Pseudorobillarda.
