The phylogenetic relationships of the monospecific genus Paratricharia, with the single species P. paradoxa, within the family Gomphillaceae are resolved using newly generated sequences of the mtSSU and nuLSU markers for three specimens collected in Costa Rica. The results support placement as sister to the genus Caleniopsis, the two genera sister to a clade containing the genera Aulaxina and Aulaxinella. This placement confirms earlier studies based on cladistic analysis of phenotype characters and phenotype-based phylogenetic binning, suggesting that apothecial features are more informative for the phylogenetic placement of taxa within Gomphillaceae than thallus characteristics.

Schistophoron indicum, a new lichen species, is described from India. It is characterized by lirellate mazaediate ascomata and dark brown, broadly ellipsoid to subglobose, bilocular to tetralocular-submuriform, smooth-walled, small ascospores.

The Thelotremataceae are represented on Aldabra by three species: Leucodecton compunctum, Thelotrema euphorbiae, and Thelotrema hniatukii. The latter is described here as new. It is closely related to T. euphorbiae and know so far only from Aldabra.
