Dyplolabia ochrocheila (Vain.) Rivas Plata & Lücking , comb. nov. ( Fig. 5D–F )

MycoBank MB817439

Basionym: ― Graphis ochrocheila Vain., Hedwigia 46: 178 (1907).

Type: ― THAILAND. Trat: Koh Chang Island ; 1900, J. Schmidt s.n. (holotype TUR-VAINIO 27535 !) .

Remarks: ―This species was considered a synonym of Dyplolabia afzelii , but differs by the extremely long ascomata and the smaller ascospores, as well as the more yellowish cover of the lirellae (old collections of D. afzelii retain a white cover). Only two collections are known from this taxon so far, from Sri Lanka and Thailand, and this taxon needs further study.

Additional specimen examined: ― SRI LANKA. South of the island, s.dat., G. Thwaites 150 (FH).
