AbstractNon-saxicolous lecideoid lichens form a diverse and polyphyletic group of species with a worldwide distribution. The phylogenetic relationships of the taxa and major clades are still largely unresolved. Here we introduce a new genus Palicella Rodr. Flakus & Printzen for Lecidea glaucopa Hook. f. & Tayl. and two closely related species. Our molecular phylogenetic results, based on maximum likelihood and Bayesian phylogenetic trees, and a combined dataset of five gene loci (ITS, nrLSU, mrSSU, RPB1 and RPB2), indicate that Palicella forms a monophyletic clade sister to Lecanora symmicta and Pyrrhospora quernea. The new genus is characterized by biatorine apothecia, which are often darkened (by the pigment Cinereorufa-green), an exciple of radiating, narrow hyphae with strongly elongate lumina, a hymenium with branched and sparsely anastomosed paraphyses, an ascus with a broad axial body surrounded by a distinct darker staining layer, and narrowly ellipsoid ascospores. Atranorin is present in all, usnic acid in two and pannarin in one species of the genus. Three new combinations are proposed: Palicella filamentosa (Stirt.) Rodr. Flakus & Printzen, P. glaucopa (Hook. f. & Taylor) Rodr. Flakus & Printzen, and P. schizochromatica (Pérez-Ortega, T. Sprib. & Printzen) Rodr. Flakus & Printzen. The molecular phylogenetic analysis confirms that Lecidea hercynica Hauck & Schmull is a synonym of P. filamentosa. An identification key to the species is provided.

Two new species of Tomentella from the Lesser Xingan Mts. of northeastern China, T. pallidocastanea and T. tenuirhizomorpha, are described and illustrated using morphological characteristics and molecular phylogenetic analysis. T. pallidocastanea is characterized by mucedinoid basidiocarps adherent to the substrate, a light reddish brown to pinkish grey hymenophoral surface, absence of rhizomorphs and cystidia, generative hyphae with clamps, rarely with simple septa and echinulate, and subglobose to lobed basidiospores (echinuli up to 1.5 μm long). T. tenuirhizomorpha is characterized by mucedinoid basidiocarps separable from the substrate, a greyish brown to dark brown hymenophoral surface, thin rhizomorphs in the subiculum and margins, an absence of cystidia, generative hyphae with clamps rarely with simple septa and echinulate, and subglobose to globose basidiospores (echinuli up to 1.5 μm long). Molecular analyses using Maximum Likelihood, Maximum Parsimony and Bayesian Analysis confirm the phylogenetic position of the two new species. The discriminating characters of these two new species and their closely related species are discussed in this study.

AbstractThe identity of Lecanora ecorticata has been uncertain due to conflicting reports of the presence of zeorin and the loss of the holotype. Phylogenetic analysis suggests that the species probably belongs in Ramalinaceae, where it is the first leprose species reported. Zeorin was found to be absent in recently collected material of L. ecorticata, including specimens from the type locality, and the report of zeorin in the lost holotype is considered to be due to contamination. A new genus, Lithocalla, is erected to accommodate L. ecorticata and a second closely related species, that occurs in the Falkland Islands, is newly combined as Lithocalla malouina. A lectotype is selected for L. ecorticata. Lithocalla is characterized by a leprose thallus containing usnic acid with fatty acids and terpenoids, but no zeorin; ascomata and conidiomata are unknown.

This paper describes a new genus of Nesticidae based on morphology of the genital characters and supported by molecular data. The new genus, Domitius n. gen., includes a group of seven cave-dweller species spread along western European peninsulas (Iberian and Italian). Molecular phylogenetic analysis shows that these species constitute an independent and highly supported evolutionary lineage being the sister group to Kryptonesticus Pavlek & Ribera, 2017, Nesticus Thorell, 1869 and Carpathonesticus Lehtinen & Saaristo, 1980 genera. As a result, seven new combinations are here proposed: Domitius baeticus (López-Pancorbo & Ribera, 2011) n. comb., Domitius murgis (Ribera & De Mas, 2003) n. comb., Domitius lusitanicus (Fage, 1931) n. comb., Domitius luquei (Ribera & Guerao, 1995) n. comb., Domitius sbordonii (Brignoli, 1979) n. comb., Domitius menozzii (Caporiacco, 1934) n. comb., Domitius speluncarum (Pavesi, 1873) n. comb.

Molecular Phylogenetic Data

Phylogenetic position of the unique grass genus Coleanthus within the tribe Poeae s. str. is discussed based on molecular phylogenetic analysis of the marker sequences, ITS and trnL–trnF. Moreover, taxa more or less related to Coleanthus were involved in our study for the maximal accuracy of the molecular phylogenetic analysis. Subtribe Coleanthinae (=Puccinelliinae) is monophyletic according to both datasets, nuclear and chloroplast genes, that probably shows certain evolutionary distance from other Poeae s. str. We confirmed the results of previous morphological studies that placed Coleanthus close to the genus Phippsia but at the same time we have not found any evidences of the affinity between the genus Phippsia and the second putative ancestor, Deschampsia. The clade which contains Coleanthus and Phippsia occupies the sister position to all other genera of the subtribe Coleanthinae. The genus Phippsia produces hybrids with Puccinellia, ×Pucciphippsia, but the relationship obtained by our data is far more distant that was considered before from its morphological features. The genus Puccinellia forms a single monophyletic clade—sister to the genus Sclerochloa and former Colpodium s. l. (Paracolpodium, Catabrosella) which are monophyletic with Catabrosa. In partial contradiction to previous research (Soreng et al. 2015)—we found that the subtribe Coleanthinae is rather distant from two-chromosome grasses in ITS analysis though chloroplast genes show the sister position of the species from the 2-chromosome grasses group, Colpodium versicolor (2n = 4), to Coleanthinae. Also we detected multiple reticulation events in the tribe Poeae s. str. and some of them—within the subtribe Coleanthinae. This can explain an uncertain position of the two-chromosome grasses in relation to Coleanthinae.

A revised generic synopsis of sub-Saharan Hyacinthaceae is presented, based on a molecular phylogenetic analysis of the family. Generic rank is accorded only to reciprocally monophyletic clades that can be distinguished by recognizable morphological discontinuities, thereby permitting an appropriate generic assignment of species not included in the analysis. Three subfamilies are recognized within the region. Subfamily Ornithogaloideae, characterized by flattened or angular seeds with tightly adhering testa, is considered to include the single genus Ornithogalum, which is expanded to include the genera Albuca, Dipcadi, Galtonia, Neopatersonia and Pseudogaltonia. Recognizing any of these segregates at generic level renders the genus Ornithogalum polyphyletic, while subdivision of Ornithogalum into smaller, morphologically distinguishable segregates in order to preserve the monophyly of each is not possible. Subfamily Urgineoideae, characterized by flattened or winged seeds with brittle, loosely adhering testa, comprises the two mainland African genera Bowiea and Drimia. The latter is well circumscribed by its deciduous, short-lived perianth and includes the previously recognized genera Litanthus, Rhadamanthus, Schizobasis and Tenicroa. The monotypic Madagascan Igidia is provisionally included in the subfamily as a third genus on the basis of its seeds, pending molecular confirmation of its relationships. Subfamily Hyacinthoideae resolves into three clades, distinguished as tribes Hyacintheae (strictly northern hemisphere and not treated further), Massonieae and Pseudoprospereae tribus nov. Full descriptions and a key to their identification are provided for all genera. New combinations reflecting the generic circumscriptions adopted here are made for most African and all Indian and Madagascan species.

The generic taxonomy of the Nothofagaceae is revised. We present a new phylogenetic analysis of morphological characters and map these characters onto a recently published phylogenetic tree obtained from DNA sequence data. Results of these and previous analyses strongly support the monophyly of four clades of Nothofagaceae that are currently treated as subgenera of Nothofagus. The four clades of Nothofagaceae are robust and well-supported, with deep stem divergences, have evolutionary equivalence with other genera of Fagales, and can be circumscribed with morphological characters. We argue that these morphological and molecular differences are sufficient for the four clades of Nothofagaceae to be recognised at the primary rank of genus, and that this classification will be more informative and efficient than the currently circumscribed Nothofagus with four subgenera.        Nothofagus is recircumscribed to include five species from southern South America, Lophozonia and Trisyngyne are reinstated, and the new genus Fuscospora is described. Fuscospora and Lophozonia, with six and seven species respectively, occur in New Zealand, southern South America and Australia. Trisyngyne comprises 25 species from New Caledonia, Papua New Guinea and Indonesia. New combinations are provided where necessary in each of these genera.

A New Species

Because of the problematical identity and status of the type of the xeniid soft coral genus Cespitularia Milne-Edwards & Haime, 1850, the species C. stolonifera Gohar, 1938 is revised. Examination of the type colonies has led to the establishment of the new genus Unomia gen. n. which is described and depicted. This genus features a stalk, commonly divided into branches featuring a diffuse polypiferous part consisting of distal clustered polyps and proximal individual ones on the stalk or the basal membranous part of the colonies. The sclerites are ellipsoid platelets composed of dendritic calcite rods whose tips are distinct on the surface of the platelets. Freshly collected material from Venezuelan reefs where the species is invasive was subjected to molecular phylogenetic analysis, the results of which substantiate the taxonomic assignment of the new genus under U. stolonifera comb. n. A new species, U. complanatis, from Japan and Green Island (Taiwan) is described and further illustrates the extent of the interspecific morphological variation within the genus. The results reveal that the biogeographic distribution of Unomia gen. n. includes Pacific Ocean reefs in addition to the previously reported invaded Caribbean reefs.

Subtropical Species

The phylogenetic placement of Chapsa lamellifera, C. megalophthalma and Diploschistes ocellatus was studied using a dataset of five genetic markers (mtSSU, nuLSU, RPB1, RPB2 and ITS). As extratropical species occurring in Australasia, C. lamellifera and C. megalophthalma differ from other species in that genus by having relatively large ascomata with muriform ascospores and complex chemistry of either the protocetraric or stictic acids chemosyndrome. D. ocellatus is unique within Diploschistes, in lacking lateral paraphyses and containing the norstictic acid chemosyndrome. Previous phylogenetic analysis gave inconclusive results regarding the phylogenetic position of these taxa, and hence in the present study, a larger sampling of molecular markers was employed. Our results demonstrated that the two Chapsa species and D. ocellatus are not part of their current genera. Consequently, the new genera Gintarasia Kraichak, Lücking & Lumbsch and Xalocoa Kraichak, Lücking & Lumbsch are described to accommodate these species. The new combinations Gintarasia lamellifera (Kantvilas & Vězda) Kraichak, Lücking & Lumbsch, G. lordhowensis (Mangold) Kraichak, Lücking & Lumbsch, G. megalophthalma (Müll. Arg.) Kraichak, Lücking & Lumbsch and Xalocoa ocellata (Vill.) Kraichak, Lücking & Lumbsch are also proposed.

Morphologically, recognition of the genus Plagiomnium may be relatively easy. Yet identifications of closely related species have met great difficulties. The contemporary species delimitations of P. carolinianum, P. maximoviczii, and P. rhynchophorum largely based on sexuality as the sole distinction have not been satisfactory. As shown from literature, character variations among these three taxa were continuous and intergraded within or among different populations throughout a wide geographic range. No gametophytic characters could be reliably used to distinguish them from each other. Molecular phylogenetic analyses using ITS2 and rps4 gene were undertaken to resolve delineations for these three morphologically similar species. The results suggest that they form a well support monophyletic clade, which can be defined as representing one single species with two subspecies, i.e. P. rhynchophorum subsp. maximoviczii and P. rhynchophorum subsp. rhynchophorum. The present molecular study supports the treatment of P. carolinianum as synonym of P. rhynchophorum as purposed previously by Koponen based on morphology.
