A new genus and species of lichenicolous fungi, Macroskyttea parmotrematis, inhabiting thalli of Parmotrema aberrans and P. ultralucens, is described from montane forests in Bolivia. The new genus is similar to Skyttea and Diplolaeviopsis from which it clearly differs in larger apothecia with widely exposed black pigmented discs, macroscopically easily visible long excipular hairs covering the whole exciple, and different ascus structure. Our results based on Maximum Likelihood (ML) and Bayesian analysis of three loci (nuSSU, nuLSU and 5.8S of the ITS) suggest that the new genus belong to Helotiales and is sister to Diplolaeviopsis ranula within encoelioid-clade. The conidial-ascosporic connection of Diplolaeviopsis ranula is shown here based on the nucleotide match of rDNA sequences.

AbstractThe lichenicolous fungi growing on Graphidales hosts in Florida are revised, mainly based on collections by the second author (R. C.). Twenty-one species are recognized. The new genus and species Lawreya glyphidiphila is described for a common asexual fungus growing on Glyphis scyphulifera and more rarely Trypethelium eluteriae, characterized by black stromatic conidiomata in which subspherical conidiogenous loculi develop, producing aseptate, subglobose, brown conidia. Nine additional new species are described: Amerosporiopsis phaeographidis (on Phaeographis brasiliensis), Arthonia acanthotheciicola (on Acanthothecis floridensis), A. subgraphidicola (on Graphis assimilis), Hemigrapha graphidicola (on G. assimilis), Skyttea graphidicola (on Graphis spp.), Strigula graphidicola (on G. assimilis), S. perparvula (on Graphidales), Talpapellis graphidis (on Graphis caesiella) and Tremella wedinii (on Glyphis scyphulifera). Phylogenetic placements of Lawreya glyphidiphila, Skyttea graphidicola and Tremella wedinii are presented. Identification keys are given for the species of Cornutispora and Talpapellis, and for the 66 species known to grow on Graphidales hosts worldwide.

Recent Origin

The new, small cavernicolous species Helmablatta louisrothi gen. et sp. n. (Nocticolidae) from the Tan-Phu cave (Vietnam) is one of the most morphologically interesting cockroaches. The extremely modified upstanding tergal gland composite from three tergites and may serve for gripping the female head during copulation. This presumption is supported by the presence of a central big hook on tergite 8. Furthermore, both wing pairs are uncommonly adapted to help releasing sex pheromones without raising the wings. Histone 3 DNA-based maximum likelihood analyses indicate a recent origin and close phylogenetic relationship between Nocticola spp. and Helmablatta sp.—consistent with the Quaternary age of the source lava tubes.

Phylogenetic Affinities

Cercosaurine lizards (subfamily Cercosaurinae of the family Gymnophthalmidae) represent a substantial component of the reptile fauna in the Neotropics. Several attempts have been made to reconstruct the phylogenetic relationships within this group, but most studies focused on particular genera or regions and did not cover the subfamily as a whole. In this study, material from the montane forests of Peru was newly sequenced. In combination with all cercosaurine sequences available on GenBank, an updated phylogeny of Cercosaurinae is provided. Monophyly was not supported for three of the currently recognised genera (Echinosaura, Oreosaurus, and Proctoporus). The genus Proctoporus is formed by five monophyletic groups, which should be used in future taxonomic revisions as feasible entities. Recognition of two previously identified undescribed clades (Unnamed clades 2 and 3) was supported and yet another undescribed clade (termed here Unnamed clade 4), which deserves recognition as an independent genus, was identified herein. Selvasaurabrava, a new genus and new species of arboreal gymnophthalmid lizard is described from the montane forests of the Pui Pui Protected Forest, Provincia de Chanchamayo, Región Junín, Peru. The new species is characterised by its small size (SVL 42.1–45.9 mm), slender body, smooth head shields, presence of paired prefrontal shields, fused anteriormost supraocular and anteriormost superciliary shields, transparent not divided lower palpebral disc, slightly rugose subimbricate rectangular dorsal scales in adults (slightly keeled in juveniles), distinctly smaller but non-granular lateral scales, smooth squared to rectangular ventral scales, and hemipenial lobes large, distinct from the hemipenial body. Phylogenetic affinities of the new genus to the other cercosaurine genera, as well as basal phylogenetic relationships between the other cercosaurine genera remain unresolved.

Didymosphaeria spartii was collected from dead branches of Spartium junceum in Italy. Multi-gene phylogenetic analyses of ITS, 18S and 28S nrDNA sequence data were carried out using maximum likelihood and Bayesian analysis. The resulting phylogenetic trees showed this to be a new genus in a well-supported clade in Massarinaceae. A new genus Pseudodidymosphaeria is therefore introduced to accommodate this species based on molecular phylogeny and morphology. A illustrated account is provided for the new genus with its asexual morph and the new taxon is compared with Massarina and Didymosphaeria.

The lichenicolous fungus Rhagadodidymellopsis endocarpi (Dothideomyceta) growing on the thallus of the terricolous lichen Endocarpon pusillum is described from Spain and Australia as new to science. The new genus and species is compared with other taxa from the genera Didymellopsis and Zwackhiomyces (Xanthopyreniaceae, Collemopsidiales, Dothideomyceta), in particular with D. perigena, a species also having hyaline didymospores and also growing on Endocarpon. Rhagadodidymellopsis endocarpi is characterized by its almost completely superficial stromatic ascomata with a coarse and irregular surface, and an ascomatal wall of very irregular thickness, and ascospores smaller than those of D. perigena. We also compare the new species with other Endocarpon parasites, including Arthopyrenia symbiotica. This is a misunderstood species, originally described as Verrucaria symbiotica, which we also discuss in detail in this study.

AbstractThe new genus Sinuicella, an early successional lichen, was found on bare soil in Oregon, USA. The thallus is minute fruticose, grey to nearly black, branching isotomic dichotomous, branches round, 20–90 μm wide in water mount. The cortex is composed of interlocking cells shaped like jigsaw puzzle pieces. Spores are hyaline, 1-septate, 25–40(–50) × 6.5–9(–11) μm. Maximum likelihood phylogenetic analyses on multilocus data sets, first spanning the entire order Peltigerales and then restricted to Peltigeraceae with extended sampling from Solorina and Peltigera, revealed the placement of Sinuicella outside of currently recognized genera, sister to Peltigera, with high support. Based on the phylogenetic, morphological and ecological distinctness of Sinuicella, we formally introduce a new genus represented by the single species S. denisonii. The cyanobiont of S. denisonii is Nostoc from phylogroup XL, Clade 2, Subclade 3 based on the rbcLX marker.

AbstractThe generic name Paralethariicola gen. nov. is introduced for a lichenicolous fungus very similar to Lethariicola, but differing by the presence of excipular hairs, asci with a hemiamyloid apical ring and a more flattened apex, curved or slightly helicoid ascospores with ± pointed ends, and thicker paraphyses. The single species, Paralethariicola aspiciliae sp. nov., is lichenicolous on Aspicilia, and is known from continental Spain and Sardinia.

AbstractGalbinothrix caesiopruinosa is described from Japan and Korea. The new genus and species is placed in Chrysotrichaceae by its ascoma morphology and by a phylogenetic analysis of mtSSU and nLSU sequence data using Bayesian and maximum likelihood inference. The monotypic genus Galbinothrix is superficially similar to Chrysothrix caesia in having dark brown ascomata covered by a thin bluish grey pruina, reddish brown ascomatal pigment in the epithecium and proper exciple, the greyish green to yellowish olive thallus, and usnic acid as the main secondary thallus compound. It differs from this species and all other Chrysotrichaceae by its large, oblong, thick-walled ascospores with a distinct epispore, the narrowly clavate to almost tubular asci, and the never clearly granular to leprose thallus.
