Klára Verseghy used the term "Fragm. typi" in her catalogue of the type specimens deposited in BP. However, this status is in conflict with the Code. "Fragm. typi" were replaced by lectotype and isolectotype of the following names: Buellia samothrakiana, Caloplaca servitiana, Catillaria servitii, Catillaria zsakii, Lecania nylanderiana var. ochracea, Lecanora atra var. aegaeica, L. cengiae-samboae, L. rhodi, Lecidea aegaeica f. acrustacea and Rinodina samothrakiana.

The new species Megaspora rimisorediata Valadbeigi & A. Nordin is described from Iran, where it mainly grows on tree bark but also on calciferous rocks and mosses. It is characterized by a pale ochraceous to bluish grey, cracked and sorediate thallus, very rarely producing ascomata. It appears to be rather commonly distributed in Iran. Its close affinity with Megaspora verrucosa is illustrated in a graph resulting from a phylogenetic network analysis of nuclear rDNA ITS1-5.8S-ITS2 sequences from specimens representing the different genera of Megasporaceae.
