Xenodevriesia

Xenodevriesia Crous, in Crous et al., Fungal Systematics and Evolution 3: 123 (2019).

        Index Fungorum number: IF 829365; Facesoffungi number: FoF 06988, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.

Saprobic or pathogenic on host substrate. Sexual morph: Unknown. Asexual morph: Mycelium comprising medium brown, smooth, septate, branched hyphae. Conidiophores dimorphic. Micro conidiophores reduced to conidiogenous cells on hyphae, erect, cylindrical, medium brown, smooth with truncate ends, proliferating sympodially. Macroconidiophores erect, cylindrical, straight to geniculate-sinuous, medium brown, smooth, unbranched or branched above, septate. Conidiogenous cells terminal or lateral on branched conidiophores, medium brown, smooth, cylindrical, proliferating sympodially; loci truncate, inconspicuous, somewhat darkened, not refractive. Conidia medium brown, smooth, guttulate, subcylindrical to narrowly obclavate, apex obtuse to truncate, base truncate, occurring in branched chains, septate; hila inconspicuous to somewhat darkened and thickened, not refractive (adapted from Crous et al. 2019).

 

Type species: Xenodevriesia strelitziicola (Arzanlou & Crous) Crous

 

Notes: Xenodevriesia is morphologically similar to Devriesia but phylogenetically distinct. Xenodevriesia is unique in that it does not form chlamydospores and the conidial hila are rather darkened and thickened. Molecular markers available for Xenodevriesia are LSU and ITS.
