- Crypthonia with 11 species is described as belonging to the Arthoniaceae. The new genus is characterised by (1) white to pale carneous, maculiform ascomata lacking a distinct exciple, (2) a weakly gelatinised, hydrophobic hymenium of paraphysoids, (3) a discontinuous layer of branched ascogenous hyphae in the hypothecium, (4) small, clavate to broadly clavate asci of the Arthonia-type lacking a hemiamyloid ring structure in the tholus, (5) eight small, hyaline, 1-3-septate, thin-walled ascospores per ascus, (6) loosely attached thalli with a byssoid, coloured hypothallus, and (7) a chemistry of mainly beta-orcinol depsidones and tridepsides including psoromic, norstictic, and gyrophoric acids. Rugulosin occurs in C. bella and C. citrina. Crypthonia athertoniensis Frisch & G. Thor, C. bella Frisch & G. Thor, C. brevispora Frisch & G. Thor, C. citrina Frisch & G. Thor, C. olivacea Frisch & G. Thor, C. palaeotropica Frisch & G. Thor, and C. vandenboomii Frisch & G. Thor are described. C. albida (F,e) Frisch & G. Thor, C. biseptata (Aptroot & Wolseley) Frisch & G. Thor, C. mycelioides (Vain.) Frisch & G. Thor, and C. polillensis (Vain.) Frisch & G. Thor are new combinations. The delimitation from similar genera and the position within the Arthoniaceae is discussed.
