Ameliella Fryday & Coppins gen. nov. is proposed to accommodate two inconspicuous, undescribed species, A. andreaeicola and A. grisea, collected from high altitude in the Scottish Highlands. Outside the Scottish Highlands, Ameliella andreaeicola is known from single collections from Norway and Canada, and A. grisea from a single collection from Norway. The new genus appears to have some affinity with Miriquidica.

The preparation of the new edition of The Lichen Flora of the British Isles necessitates the publication of several taxonomic and nomenclatural novelties. The following new species are described: Anisomeridium robustum (Monoblastiaceae), Antennulariella lichenisata (Antennulariellaceae), Fellhanera duplex (Pilocarpaceae), Gyalideopsis crenulata (Gomphillaceae), Micarea farinosa (Pilocarpaceae) and Xerotrema quercicola (Odontotremataceae). Antennulariella lichenisata is the first lichenized member of the order Capnodiales to be described. The following new combinations are proposed: Bacidia squamellosa, Catillaria lobariicola, Collemopsidium arenisedum, C. argilospilum, C. caesium, C. chlorococcum, C. monense, C. subarenisedum, Miriquidica pycnocarpa f. sorediata, Pyrenocarpon thelostomum, Topeliopsis azorica, and Verrucaria nigrescens f. tectorum.

The new species Miriquidica effigurata, M. squamulosa and Pertusaria stellata are described from the southern subpolar region from collections made by Henry Imshaug and co-workers in the early 1970s. All three species occur on Campbell Island, New Zealand, with M. effigurata and P. stellata also occurring on the Auckland Islands, New Zealand, and P. stellata also being reported from Isla Desolación in southern Chile. Miriquidica effigurata and M. squamulosa are similar to M. complanata but have apothecia with a dark (K+ purple-red) lower hypothecium and thalli containing confluentic acid and norstictic acid respectively. Pertusaria stellata is similar to P. macloviana, but has shorter ascospores and a smoother, generally paler thallus lacking papillate isidia. Cephalodia are reported for the first time in both Miriquidica and Pertusaria.
