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, made up of cells of textura angularis. Paraphyses septate, unbranched, hypha-like. Asci 8-spored, ellipsoid to fusoid, without a refractive canal at apex. Ascospores biseriate, brown, ellipsoid-fusoid, 1-septate, ends truncate, with gelatinous appendages at each 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 apex. Conidia ellipsoid to oblong, straight to slightly curved, thick-walled, transversely euseptate with oblique septa (adapted from Crous et al. 2019).

 

 

Type species: Neophaeoappendicospora leucaenae Crous & M.J. Wingf., in Crous, Schumacher, Akulov, Thangavel, Hernández-Restrepo, Carnegie, Cheewangkoon, R; Wingfield, Summerell, Quaedvlieg, Coutinho, Roux, Wood, Giraldo & Groenewald, Fungal Systematics and Evolution 3: 97 (2019)

 

Notes: Neophaeoappendicospora was isolated from Leucaena leucocephala from France, which is a source of quality animal feed, firewood or used in charcoal production, green manure and biomass, food for humans and pulpwood for paper industry. The genus resembles Phaeoappendicospora. Neophaeoappendicospora leucaenae, the type species of Neophaeoappendicospora differs from the type species of Phaeoappendicospora, P. thailandensis, primarily by their ascospores size (Crous et al. 2019). Neophaeoappendicospora also easily forms asexual morph in cultures contrary to Phaeoappendicospora (Senanayake et al. 2017, Crous et al. 2019).
