Type species – Selenophoma catananches Maire [as ‘catanaches’], Bull. Soc. bot. Fr. 53: clxxxvii (1906).
Notes – The genus is characterized by immersed, branched, septate, pale brown mycelium, with immersed or superficial, separate or aggregated, scattered pycnidial or avervular, lacking ostioles, conidiophores reduced to conidiogenous cells or hyaline, 1–3-septate, irregularly branched at the base and above. Conidiogenous cells are enteroblastic, phialidic, discrete, determinate, subglobose, obpyriform or obovoid, formed from the inner cell of the pycnidial wall, and hyaline to pale brown. Conidia are holoblastic, fusiform, ellipsoidal to obovoid, aseptate, hyaline or pale brown, eguttulate or irregularly guttulate, smooth- to verruculose-walled (Cheewangkoon et al. 2009, facesoffungi.org 2020). Sutton (1980) accepted five species in Selenophoma and the graminicolous Selenophoma species have been accommodated in Pseudoseptoria which is the earliest available generic name. Sutton (1996) introduced S. anniae, while Cheewangkoon et al. (2009) introduced S. australiensis with Hormonema as a synasexual morph. In the present phylogenetic analysis, three Selenophoma species (S. australiensis, S. linicola and S. mahoniae) grouped in three different clades (Fig. 27) and this is similar to the results shown by Thambugala et al. (2014a). Therefore, more species including the type of this genus need to be re-collected and sequenced in order to confirm their taxonomic placement.
