Englerula
Englerula Henn., Bot. Jb. 34: 49 (1904).
= Anatexis Syd., Annls mycol. 26(1/2): 90 (1928).
Index Fungorum number: IF 1820; Facesoffungi number: FoF 07961, 10 morphological species (Species Fungorum 2022), no molecular data available.
Saprobic or epiphytic on leaves, primarily tropical. Colonies on both leaf sides, superficial, thin to dense, round to irregular, dark brown to black, confluent, velvety. Hyphae superficial, straight to curved, septate, irregular to reticulately branched, and acute to wide angles, brown. Hyphopodia absent. Sexual morph: Ascomata perithecioid, superficial on hyphae, scattered, globose to subglobose, brown to black, non-ostiolate, containing few asci. Peridium thin, membranous. Pseudoparaphyses absent. Asci 8-spored, bitunicate, thick-walled, obovoid to subclavate, globose to subglobose, with a thick ocular chamber and apex. Ascospores multiseriate, fusiform, broadly ellipsoid to subobovoid, yellowish brown to dark brown, uniseptate, smooth-walled, constricted at the septum, ends rounded, surrounded by remnants of mucilage. Asexual morph: in Capnodiastrum. Conidiomata pycnidial similar to perithecia, superficial, globose, thin-walled. Conidiogenous cells holoblastic, discrete, hyaline, smooth. Conidia 1-celled, oblong to ovate, brown (adapted from Hyde et al. 2013).
Type species: Englerula macarangae Henn.
Notes: Englerula is characterised by perithecioid, superficial ascomata, thin, membranous peridium, obovoid to subclavate, globose to subglobose asci and broadly ellipsoid to subobovoid, yellowish brown to dark brown, uniseptate ascospores, surrounded by remnants of mucilage. The asexual morph is characterised by superficial, globose conidiomata, holoblastic, discrete, hyaline, smooth conidiogenous cells and 1-celled, oblong to ovate, brown conidia. Dai et al. (2014) re-examined the syntype specimen of E. macarangae (BPI 566046) and provided an updated description and illustration of the genus. Englerula is a distinct and type genus of Englerulaceae. Fresh specimens with DNA sequence data are needed to confirm the taxonomic placement of Englerula.
