Phaeoappendicosporaceae Crous & M.J. Wingf., Fungal Systematics and Evolution. 3: 96 (2019).
Index Fungorum number: IF829458; 2 species.
Saprobic on dead woody bark. Sexual morph: Pseudostroma immersed, becoming erumpent; ectostroma pale brown to grey, containing periphyses; ostioles cylindrical. Perithecia globose to lenticular, dark brown, wall of cells of textura angularis. Paraphyses septate, unbranched, hypha-like. Asci 8-spored, ellipsoid to fusoid, without a refractive canal at the apex. Ascospores brown, ellipsoid-fusoid, 1-euseptate, with gelatinous appendage at each truncate-end. Asexual morph: Coelomycetous. Conidiomata pycnidial, multilocular, forming a long neck. Paraphyses hyaline, cylindrical, septate, unbranched, hypha-like. Conidiophores subcylindrical, hyaline to pale brown, septate, unbranched. Conidiogenous cells cylindrical, hyaline to pale brown, proliferating percurrently at the apex. Conidia ellipsoid to oblong, straight to slightly curved, thick-walled, transversely euseptate with oblique septa.
Type genus – Phaeoappendicospora Senan., Q.R. Li & K.D. Hyde
Notes – Phaeoappendicosporaceae was introduced by Crous et al. (2019b) based on Phaeoappendicospora as the type genus and Neophaeoappendicospora as the second genus. Both genera have similar characters, but Neophaeoappendicospora is distinct from Phaeoappendicospora by its larger ascospores and presence of asexual morph.
Ecological and economic significance of Phaeoappendicosporaceae
All members of this family are saprobes. Neophaeoappendicospora leucaenae was isolated from Leucaena leucocephala, a commercially and environmental important Fabaceae used as fodder, charcoal, organic manure and in the paper industry. However, members in both genera are involved in nutrient recycling through litter decomposition.
