Flora hibernica, comprising the flowering plants, ferns, Characeæ, Musci, Hepaticæ, Lichenes and Algæ of Ireland, arranged according to the natural system with a synopsis of the genera according to the Linnæan system, by James Townsend Mackay.

The new generic name Bryobilimbia is proposed for Lecidea hypnorum and the closely related taxa Lecidea ahlesii var. ahlesii, L. ahlesii var. nemoralis, L. diapensiae, L. sanguineoatra and Mycobilimbia australis. A phylogenetic analysis based on five genes shows that Lecidea berengeriana does not belong to this group but is more closely related to Romjularia. Both groups of species have been included in Mycobilimbia by some authors but are instead shown to be most closely related to a group of genera (including Clauzadea, Farnoldia, Lecidoma and Romjularia) that do not belong to Lecideaceae s. str. A neotype is selected for Lichen sanguineoater Wulfen and the new combinations Bryobilimbia ahlesii var. ahlesii, B. ahlesii var. nemoralis, B. australis, B. diapensiae, B. hypnorum and B. sanguineoatra are proposed. A lectotype is also selected for L. templetonii Taylor.

“…Taylor (in Mackay 1836) mentions two collections of his new taxon: “on moss, near Belfast, Mr. Templeton ; on turf, near Bantry, Miss Hutchins ”. Both collections are present in Taylor's herbarium in FH, with a further specimen of Templeton's collection in BM ( ex hb.…”

Bryobilimbia, a new generic name forLecidea hypnorumand closely related species

“…A number of additional species which are now regarded as belonging to the genus were described during the 19th century, mainly from Europe. These include Lecidea cotaria and Parmelia elacista (Acharius 1803), Lichen glebulosus (Smith 1808), again with a good colour illustration clearly showing differences from Lichen coarctatus , Lecanora involuta (Taylor in Mackay 1836) and Lecidea pallidocervina (from Brazil, Krempelhuber 1876). A sorediate taxon was described as Biatora coarctata subsp.…”

A new species-level taxonomy forTrapelia(Trapeliaceae, Ostropomycetidae) with special reference to Great Britain and the Falkland Islands

Trapelia is a small genus of worldwide distribution. Trapelia coarctata has long been regarded as a morphologically variable species and phylogenetic studies have suggested that it is non-monophyletic, or at least that species are frequently misidentified. The phylogenetic relationships of freshly-collected material of Trapelia were studied using ITS, mitochondrial SSU rDNA and to a small extent also beta-tubulin sequence data, together with chemical and morphological characters. Sequence data combined with morphology and chemistry confirm that the diversity of the genus at species-level has been underestimated. Trapelia coarctata is defined in a more restricted way and many specimens previously referable to this taxon are assigned to the reinstated species T. elacista, which differs in subtle morphological characters including a crack separating the thallus and apothecium in well-developed thalli. Trapelia involuta is reinstated as a separate, though closely related, species to T. glebulosa based on sequence data, morphology and chemistry, and is lectotypified. Trapelia collaris is a distinctive species described as new from Great Britain which has an extensive, cracked thallus with abruptly thickening marginal areoles arising on an inconspicuous prothallus, relatively small apothecia (rarely exceeding 300 µm diameter) and contains 5-O-methylhiascic acid as the major secondary substance. Trapelia obtegens is shown to include frequent non-sorediate morphs which have doubtless been misidentified as other species. The number of species of Trapelia considered to occur in Europe is thus raised from five to eight. The genus is newly reported for the Falkland Islands where seven species occur: T. coarctata, T. placodioides, T. sitiens sp. nov. (with a thin, extensive thallus, sessile apothecia, 5-O-methylhiascic acid as the major secondary substance and the presence of conidiomata), T. tristis sp. nov. (with relatively small apothecia up to 460 µm diameter, presence of gyrophoric acid as the major substance and an absence of conidiomata) and three unidentified species represented by very sparse material. All the species studied, with the possible exception of the three unidentified species, can usually be distinguished by morphological features, particularly the method of development of the thallus and the shape and distribution of the areoles, but morphological variation in response to microhabitat variation is likely to make a proportion of specimens difficult to assign to species in the absence of sequence data.

“…The BM specimen is therefore the holotype, and Hale's lectotypification superfluous; the FH specimen is thus an isotype. In making the new combination, Poelt & Vězda (1977) wrongly gave the place of publication of Taylor's name as being in Mackay's Flora Hibernica (Mackay 1836) although with the correct page number and year for Taylor (1847). The combination is nevertheless to be treated as validly published as under Art.…”

Neo- and epitypifications to fix the application of the names Parmelina carporrhizans and P. quercina

Argüello et al. (2007) found that Parmelina quercina, as circumscribed by Hale (1976), comprised four phylogenetic species which could also be distinguished by morphological features and also had different distributions: P. carporrhizans (usually rhizinate apothecia, and distinct effigurate maculae; oceanic Europe and Macaronesia), P. coleae (usually rhizinate apothecia, narrow ascospores, and fenestrate maculae; North America), P. elixia (non-rhizinate apothecia, larger ascospores, smaller conidia, and not or faintly maculate; Australia), and P. quercina (apothecia rhizinate or not, and less distinct more rounded maculae; continental Europe).
