Pseudorobillarda

Pseudorobillarda M. Morelet

Index Fungorum number: IF 9607; Facesoffungi number: FoF 07559

 

Saprobic on decaying plant materials in terrestrial and freshwater habitats. Sexual morph: Undetermined. Asexual morph: Pycnidia solitary, scattered or gregarious, immersed, uniloculate, ellipsoidal, glabrous, dark brown to black, ostiolate. Peridium composed of several layers of cells of textura angularis or textura prismatica, darker in the outer layers, paler in the inner layers. Conidiophores sparsely septate and branched at the base or reduced to conidiogenous cells. Pseudoparaphyses present or absent, cellular. Conidiogenous cells discrete or integrated, cuboid, short-cylindrical, subcylindrical, ampulliform, or lageniform, colourless, smooth. Conidia fusiform, subcylindrical, ellipsoid, naviculate, unicellular or euseptate, hyaline, smooth, bearing attenuated, divergent appendages (Nag Raj1993). (Description from Dong et al. 2020)

 

Type species: Pseudorobillarda phragmitis (Cunnell) M. Morelet

 

Notes: Pseudorobillarda is a coelomycetous genus, characterized by hyaline conidia with divergent appendages (Nag Raj 1993). The placement of Pseudorobillarda is unstable as it either clustered with Pleosporales (Rungjindamaiet al. 2012) or nested between Tubeufiales and Mytilinidiales (Tangthirasunun et al. 2014). Recently, it was placed in a newly established family Pseudorobillardaceae which resides in Minutisphaerales (Crous et al. 2018, 2019). However, Pseudorobillardaceae was shown to not belong to Minutisphaerales in our phylogenetic tree, and therefore placed in Dothideomycetes families incertae sedis. (Notes from Dong et al. 2020)
