Swinscowia divisa (P.M. McCarthy) S.H. Jiang, Lücking & Sérus. comb. et stat. nov.

MycoBank number: MB 836410; Index Fungorum number: IF 836410; Facesoffungi number: FoF 08904.

Bas.: Strigula decipiens var. divisa P.M. McCarthy, Lichenologist 32: 34 (2000).

Notes: McCarthy (2000) considered this taxon a subspecies of S. decipiens, stating that the only difference were occasional longitudinal septa in otherwise similarly sized ascospores. However, not only is ascospore septation an important taxonomic criterion in this genus, but the ascospores of S. decipiens are also distinctly longer and narrower (see key below). As the few other known species with submuriform ascospores are different in ascospore size, morphology and/or substrate ecology, the recognition of S. divisa as a separate species is justified.
