Alanphillipsia Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol. Fungi 31: 197 (2013)


Facesoffungi number: FoF 01417


Dothideomycetes, order incertae sedis, Botryosphaeriales, Botryosphaeriaceae


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 aloes Crous & M.J. Wingf., Persoonia, Mol. Phyl. Evol. Fungi 31: 197 (2013)                             


Notes: Crous et al. (2013) introduced Alanphillipsia with A. aloes as the type species. In morphology, Alanphillipsia resembles Aplosporella (Sutton 1980; Slippers et al. 2013), but the former is somewhat distinct as it has a hyaline outer layer (Crous et al. 2013). Crous et al. (2013) compared Alanphillipsia with Cytosphaera, but the latter genus has erumpent to superficial stromatic conidiomata and hyaline conidia (Sutton 1980). Based on a megablast search of NCBIs GenBank nucleotide database, Crous et al. (2013) concluded that Alanphillipsia belongs in Botryosphaeriaceae. Wijayawardene et al. (2014c) also listed Alanphillipsia under Botryosphaeriaceae as his sequence analyses is in line with that of Crous et al. (2013).
