The phylogenetic relationships within Specklinia (Pleurothallidinae; Orchidaceae) and related genera are re-evaluated using Bayesian analyses of nrITS and chloroplast matK sequence data of a wide sampling of species. Specklinia is found paraphyletic in the DNA based trees, with species alternatively assigned to Muscarella proven distinct, monophyletic and easily recognizable. Specklinia as such includes about 100 morphologically highly diverse species. Their phenotypic differences have prompted the creation of up to eleven generic names within this relatively small group. Here we show not only that these morphologically divergent species are closely related, but also that they can still be recognized by certain conserved morphological traits. The genera Acostaea, Areldia, Empusella, Cucumeria, Gerardoa, Pseudoctomeria, Sarcinula, Sylphia, Tribulago and Tridelta are found embedded within Specklinia, and therefore reduced under the synonymy of the latter. Specklinia is confirmed as sister to a clade that includes Platystele, Scaphosepalum and Teagueia. Five well-supported subgenera are proposed for Specklinia and are characterized both geographically and morphologically. The species belonging to each subgenus are listed. Incaea is synonymized with Dryadella, while Rubellia is reduced under Platystele. New combinations for several species are proposed. The criteria for the generic delimitation of Specklinia and other genera in the Pleurothallidinae are discussed.

Generic Delimitation

AbstractBryoria pseudocapillaris and B. spiralifera are currently treated as members of Bryoria section Implexae although conspicuous, long and depressed pseudocyphellae characterizing both species resemble those found in the genus Sulcaria. Both genera belong in Parmeliaceae and form an alectorioid group together with Alectoria, Gowardia and Pseudephebe. Parsimony and Bayesian analyses of ITS, partial GAPDH and partial Mcm7 sequence data were used to examine the phylogenetic position of B. pseudocapillaris and B. spiralifera, and in light of these results evaluate the generic delimitation of Bryoria and Sulcaria. A total of 110 specimens of 53 species containing representatives from alectorioid and closely related genera were included in the analyses. The results clearly show first, that both B. pseudocapillaris and B. spiralifera belong in Sulcaria rather than in Bryoria, and second, that they should be considered conspecific. Bryoria pseudocapillaris is proposed as a synonym under B. spiralifera and the name Sulcaria spiralifera comb. nov. is introduced.

We estimated phylogenetic relationships within Anathallis and related genera using Bayesian analyses of nrITS sequence data. The genus is biphyletic in the molecular trees. A novel generic concept, Lankesteriana, is proposed for the species Anathallis barbulata and 19 close relatives. The genus is more closely related to some species of Trichosalpinx and Zootrophion than to Anathallis s.s. Species previously transferred from Pleurothallis subgen. Acuminatia sect. Acuminatae to Anathallis, are here transferred to Stelis, to which they are related phylogenetically. A few additional transfers to Anathallis are made. Lankesteriana is described and characterized, and the necessary taxonomic transfers are made

Here, we test the current generic delimitation of Rostania (Collemataceae, Peltigerales, Ascomycota) utilizing molecular phylogeny and morphological investigations. Using DNA sequence data from the mitochondrial SSU rDNA and two nuclear protein-coding genes (MCM7 and β-tubulin) and utilizing parsimony, maximum likelihood and Bayesian phylogenetic methods, Rostania is shown to be non-monophyletic in the current sense. A new generic delimitation of Rostania is thus proposed, in which the genus is monophyletic, and three species (Rostaniacoccophylla, R.paramensis, R.quadrifida) are excluded and transferred to other genera. Rostaniaoccultata is further non-monophyletic, and a more detailed investigation of species delimitations in Rostania s. str. is needed. The new combinations Leptogiumparamense and Scytiniumquadrifidum are proposed.

AbstractOpegrapha multipuncta and Schismatomma quercicola are two sterile European lichens reproducing only vegetatively by means of soredia. RAxML and Bayesian analyses of newly generated sequence data from the mitochondrial ribosomal RNA small subunit provide clear evidence that these two species do not belong to the Arthoniomycetes, but to the Lecanoromycetes. In our phylogenetic analyses, O. multipuncta is nested in the genus Porina (Porinaceae) as sister to P. austroatlantica, while S. quercicola is nested in the genus Schizotrema (Graphidaceae) as sister to S. zebrinum. The following new combinations are introduced: Porina multipuncta (Coppins & P. James) Ertz, Coppins & Frisch and Schizotrema quercicola (Coppins & P. James) Ertz, Frisch & Sanderson. Schizotrema quercicola represents the first record of the genus Schizotrema for Europe and the first sorediate member in this genus. The species is newly recorded from Norway. The lichenicolous habit of Arthonia invadens is confirmed.

AbstractSpecies of Usnea with black pigmentation in the cortex and dark apothecial discs are informally referred to as neuropogonoid lichens. Here we studied the phylogenetic relationships of the core group of neuropogonoid lichens using DNA sequence data of three loci: nuclear ITS and IGS rDNA and RPB1. Maximum likelihood and Bayesian analyses revealed monophyly of 11 neuropogonoid species, with U. ciliata and U. subcapillaris forming a separate lineage. The backbone of the phylogeny of the core group was not resolved with statistical confidence, but relationships of groups of two to three species received strong support (U. acromelana +U. aurantiaco-atra; U. messutiae+U. pallidocarpa; U. sphacelata+U. subantarctica+U. trachycarpa; U. lambii+U. perpusilla+U. ushuaiensis). The new combination U. lambii (Imshaug) Wirtz & Lumbsch comb. nov. is made and U. messutiae Wirtz & Lumbsch sp. nov. is described.
