Libertasomyces

Libertasomyces Crous & Roets, in Crous et al., Persoonia 36: 375 (2016).

 Index Fungorum number: IF 817046; Facesoffungi number: FoF 08264, 4 morphological species (Species Fungorum 2022), 4 species with molecular data.

Saprobic on twigs. Sexual morph: Unknown. Asexual morph: Conidiomata pycnidial, solitary, dark brown, erumpent, globose, with central ostiole. Conidiomatal wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, hyaline, smooth, ampulliform to doliiform, phialidic with prominent periclinal thickening. Conidia solitary, hyaline, smooth, granular, thin-walled, ellipsoid, widest in middle, apex obtuse, base truncate to bluntly rounded, aseptate (adapted from Crous et al. 2016).

 

Type species: Libertasomyces myopori Crous & Roets

 

Notes: Libertasomyces is characterised by erumpent, dark brown conidiomata, hyaline, smooth, ampulliform to doliiform, phialidic conidiogenous cells and hyaline, granular, ellipsoid to muriform, aseptate conidia with an obtuse apex. Libertasomyces is morphologically and phylogenetically a distinct genus in Libertasomycetaceae. Molecular markers available for Libertasomyces include LSU, ITS BTUB, RPB2 and TEF-1.
