Pseudophaeophleospora

Pseudophaeophleospora C. Nakash., Videira & Crous, in Videira et al., Stud. Mycol. 87: 311 (2017)

Index Fungorum number: IF 822700; Facesoffungi number: FoF 08554, 3 morphological species (Species Fungorum 2021), 3 species with molecular data

Phytopathogenic. Sexual morph: Unknown. Asexual morph: Conidiomata amphigenous, globose, wall with up to four layers of dark brown textura angularis, subepidermal, scattered, rarely aggregated, with a central ostiole from where conidia exude in a cirrhus. Conidiophores absent or reduced to only two cells. Conidiogenous cells pale brown, smooth to finely verruculose, ampulliform to doliiform, subcylindrical, proliferating percurrently near apex. Conidia formed singly, pale to dark brown, smooth to slightly verruculose, guttulate, subcylindrical to narrowly obclavate, slightly fusiform, straight, multiseptate, with apical cell tapering into an obtuse apex, widest at basal septum and tapering to a subtruncate base, hilum flattened with minute marginal frill (Adapted from Videira et al. 2017).

 

Type species: Pseudophaeophleospora stonei (Crous) C. Nakash., Videira & Crous

 

Notes: Pseudophaeophleospora was introduced by Nakashima et al. in Videira et al. (2017) with P. stonei as type species. Pseudophaeophleospora is unique in having conidiophores which are reduced to conidiogenous cells that are pale brown, and the conidia are obclavate to cylindrical. Pseudophaeophleospora differs from Phaeophleospora in having conidiophores arising from hyphae without stromata composed from swollen hyphal cells. These two genera can be differentiated based on DNA sequence data.
