Endophytic, saprobic or possibly pathogenic, associated with leaf lesions. Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, immersed, globose, central, dark brown, ostiolate. Conidiomata wall composed of brown walled cells of textura angularis. Paraphyses subcylindrical, unbranched or branched at base, aseptate or transversely septate, with obtuse to subobtuse apices, hyaline, smooth-walled. Conidiophores subcylindrical, flexuous or straight, septate, hyaline, smooth-walled. Macroconidiogenous cells proliferating percurrently, subcylindrical to lageniform, terminal, integrated, hyaline, smooth. Macroconidia ellipsoid to obclavate or subcylindrical with truncate scar on hyaline layer, solitary, hyaline when young, becoming golden brown to medium brown, verruculose, granular to guttulate, surrounded by a persistent, hyaline outer layer (absent in some species, or reduced to a basal frill or basal and apical appendage). Microconidiogenous cells in

the same conidioma, hyaline, smooth, subcylindrical, proliferating inconspicuously percurrently at apex. Microconidia subcylindrical to ellipsoid, apex obtuse, base truncate, hyaline, smooth-walled, granular, with a minute marginal frill (description modified from Crous et al. 2013, 2014c).

 

Type species: Alanphillipsia aloicola Crous [as ‘aloeicola’], in Crous et al., Persoonia 33: 217 (2014).
