The species described in or referred to the genus Melanophloea, traditionally referred to the Thelocarpaceae, are discussed. Detailed observations on two species, including the type species, show that they have not much more in common than their polysporous ascus. Melanophloea is reduced to the type species, M. pacifica. It shows a close resemblance to Aptrootia in the Trypetheliaceae, and it is therefore tentatively referred to this family. Melanophloea americana is shown to be close to Thelenella in the Thelenellaceae. The latter species and the related M. montana are newly combined into this genus as Thelenella americana and T. montana. Thelocarpon nigrum, which was recently compared to Melanophloea, is retained in Thelocarpon in the Thelocarpaceae. Polyspory is suggested to facilitate dispersion, especially when compared to parent taxa that produce large muriform ascospores. Based on the current classification, polyspory originated at least 57 times within the lichenized ascomycetes, a clear example of convergent evolution.

Trapeliopsis gymnidiata, a terricolous species from the Canary Islands, is described as new to science. It has previously been confused with T. wallrothii, but differs by the soft, partly decorticate isidia, or rather gymnidia, that leave inconspicuous scars after falling off. Trapeliopsis wallrothii is known only from high mountains in Macaronesia, while T. gymnidiata is a lowland species. Trapelia rubra from Madeira is also described as new to science. It grows in similar places and resembles some morphs of Trapelia coarctata, but differs by the nearly squamulose areoles, the crenulate, seemingly sorediate, apothecium margin that does not become excluded, and especially by the patchy red colour (skyrin) in the medulla.

The new species Parmeliella borbonica is described. It belongs in a small group of species, which, unlike all other Parmeliella species except those of the Parmeliella mariana group, have thalline squamulose margins of the apothecia, and are thus superficially reminiscent of Pannaria. The group is mainly Indo-pacific. A key to the species is given. Parmeliella borbonica appears to be an addition to the many remarkable endemic members of the Pannariaceae found in Réunion which has retained old Gondwana elements, as its lowland forests have not been destroyed as much as those in the neighbouring region. The very rare Coccocarpia imbricascens Nyl. was found as new to the island, and the rare endemic Pannaria multifida P. M. Jørg close to its type locality.
