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.

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.

Abstract— Hyptidinae, ca. 400 species, is an important component of Neotropical vegetation formations. Members of the subtribe possess flowers arranged in variously modified bracteolate cymes and nutlets with an expanded areole and all share a unique explosive mechanism of pollen release, except for Asterohyptis. In a recent phylogenetic study, the group had its generic delimitations rearranged with the recognition of 19 genera in the subtribe. Although the previous phylogenetic analysis covered almost all the higher taxa in the subtribe, it lacked a broader sampling at the species level. Here we present a new expanded phylogenetic analysis for the subtribe comprising 153 accessions of Hyptidinae sequenced for the nuclear nrITS, nrETS, and waxy regions and the plastid markers trnL-F, trnS-G, trnD-T, and matK. Our results widely support the previous phylogenetic results with some changes in the support and relationship between genera. It also uncovers the need for a new combination of Eriope machrisae in Hypenia and the phylogenetic position of Hyptis sect. Rhytidea, which was demonstrated to be part of Mesosphaerum. The generic delimitation in Hyptidinae is discussed, and we recommend that further studies with more markers are needed to confirm the monophyly of Hyptidendron and Mesosphaerum, as well as to support taxonomic changes on the infrageneric delimitation within Hyptis s. s.

Generic Description

Poteranthera (Melastomataceae) is a genus of small, annual herbs with narrow leaves, that inhabit humid savannas in South America and are visible only when in bloom. Due to their size and paucity of collections, the phylogenetic position of Poteranthera has been uncertain to this point. Poteranthera has been at times associated, confused, or placed in Acisanthera and/or Siphanthera. Phylogenetic analyses based on DNA sequence data place Poteranthera unequivocally within the Microlicieae and not closely related to Acisanthera or Siphantera. These results are consistent with seed and anther morphology. Putative morphological synapomorphies for this genus are the glandular hairs restricted to the leaf margins and the apically constricted hypanthium. Based on morphology, Acisanthera leptalea seems better placed in Poteranthera and the new combination Poteranthera leptalea is made. An expanded generic description is also provided.

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.

Abstract The monotypic Pleurocladopsis, endemic to Chile, was established by Schuster in 1964 based on an earlier poorly known species Cephalozia (?) simulans C. Massal. The phylogenetic position of Pleurocladopsis simulans had been considered uncertain until it was placed in the family Schistochilaceae on account of the gynoecial and sporophytic characters. It has been assumed that Pleurocladopsis represents the starting point of evolution in Schistochilaceae. In the present study, the phylogenetic position and taxonomic status of Pleurocladopsis simulans are inferred from phylogenetic analysis of three chloroplast DNA sequence data. The result suggests that the genus was established solely based on the autapomorphic characters, thus obscuring its actual phylogenetic relationship with Schistochila and that these characters are later derived rather than ancestral. The result also confirms that the gynoecial and sporophytic characters are important in taxonomy, but they may be not sufficient at the infrafamilial level and at other lower taxonomic levels. In accordance with the results of the present study, Pleurocladopsis is synonymised with Schistochila, and the new combination Schistochila simulans (C. Massal.) Xiao L. He & Yu Sun is made.

Group Relationships

The small lacewing genus Apertochrysa comprises species from Africa, Asia and Australia. All lack a tignum, but otherwise resemble distantly related genera. We show that Apertochrysa does not form a monophyletic clade, based on analyses of molecular sequence data and morphological traits such as the presence and shape of the male gonapsis, wing venation, and larval setae. Apertochrysa kichijoi forms a clade with Eremochrysa, Suarius and Chrysemosa, whereas A. albolineatoides belongs to a clade that includes Cunctochrysa. Apertochrysa albolineatoides should become a new combination as Cunctochrysa albolineatoides, while A. kichijoi will have to be transferred to a new genus. The Australian A. edwardsi, the African A. eurydera and the type species of the genus Apertochrysa, A. umbrosa, join the large Pseudomallada group. Relationships of A. umbrosa are less certain, because for it we could amplify only one of the three nuclear genes used in the overall analysis. However, in all morphological traits tested, that species strongly resembles A. edwardsi and A. eurydera and thus is very likely just another exceptional Pseudomallada lacking a tignum. The fate of the genus name Apertochrysa depends on additional molecular and morphological analyses of A. umbrosa.

AbstractDigitopodium hemileiae was described originally in 1930 as Cladosporium hemileiae; growing as a mycoparasite of the coffee leaf rust (CLR), Hemileia vastatrix, in a sample of diseased leaves of Coffea canephora collected in the Democratic Republic of Congo. No cultures from this material exist. More recently, the type material was re-examined and, based on morphological features, considered to be incorrectly placed in Cladosporium. The new genus Digitopodium was erected to accommodate this species. Interest in fungal antagonists of H. vastarix, as potential biocontrol agents of CLR, led to comprehensive surveys for mycoparasites, both in the African centre of origin of the rust, as well as in its South American exotic range. Among the rust specimens from Ethiopia, one was found to be colonized by a fungus congeneric with, and similar to, D. hemileiae. Pure cultures obtained from the Ethiopian material enabled a molecular study and for its phylogenetic position to be elucidated, based on DNA sequence data from the ITS and LSU regions. Molecular data showed that two members of the recently erected genus Hyalocladosporiella (Herpotrichiellaceae: Chaetothyriales) are congeneric with Digitopodium from Ethiopia and morphologically similar to both D. hemileiae and the two Ethiopian isolates. These isolates were found to be morphologically and genetically identical to H. tectonae, described previously from Brazil. Thus, species of Hyalocladosporiella are re-allocated to Digitopodium here; including D. tectonae, and a novel species, D. canescens, recently found in Brazil growing as a mycoparasite of Puccinia thaliae. The potential use of D. hemileiae and D. tectonae for classical biological control of CLR is discussed.

AbstractThe molecular phylogeny of extant genets (Carnivora, Viverridae,Genetta) was generated using all species with the exception of the Ethiopian genetGenetta abyssinica. Herein, we provide the first molecular phylogenetic assessment ofG. abyssinicausing molecular sequence data from multiple mitochondrial genes generated from a recent record of this species from the Forêt du Day (the Day Forest) in Djibouti. This record represents the first verified museum specimen ofG. abyssinicacollected in over 60 years and the first specimen with a specific locality for the country of Djibouti. Multiple phylogenetic analyses revealed conflicting results as to the exact relationship ofG. abyssinicato otherGenettaspecies, providing statistical support for a sister relationship to all other extant genets for only a subset of mitochondrial analyses. Despite the inclusion of this species for the first time, phylogenetic relationships amongGenettaspecies remain unclear, with limited nodal support for many species. In addition to providing an alternative hypothesis of the phylogenetic relationships among extant genets, this recent record provides the first complete skeleton of this species to our knowledge and helps to shed light on the distribution and habitat use of this understudied African small carnivore.
