Acremonium arthrinii sp. nov. was collected from Phyllostachys heteroclada in the forest of Sichuan Province, China. This mycopathogenic fungus was frequently found on the top of the ascomata of Arthrinium yunnanum, and presumably causes its death. In this study, the new species was examined morphologically and maximum likelihood and Bayesian analyses of a combined LSU, SSU, ITS and TEF 1-α were performed to clarify the taxonomic affinity of the species. Acremonium arthrinii can be distinguished from other Acremonium species based on conidiogenesis, size differences in conidiophores, conidiogenous cells and conidia, and its DNA sequence differences and phylogeny. Detailed descriptions, micrographs and phylogenetic relationships of the new taxon were provided.

A New Species

Phyllachora species usually cause leaf tar spot disease associated with living leaves in various hosts. In this study, a sample of stem tar spot was collected from a Phyllostachys heteroclada forest in Ya’an City, Sichuan Province, China. Here we introduce a new taxon in the genus Phyllachora through using morphology, information on host and multigene phylogeny of three genes (LSU, SSU, ITS). Within the family Phyllachoraceae, members of the genus Phyllachora form five groups with maximum likelihood and Bayesian phylogenies. The new species Phyllachora heterocladae clusters with eight undetermined Phyllachora species in a highly supported clade and morphologically differs from other similar species in having relatively long asci with a noticeable apical ring, fusiform to ellipsoid ascospores with many guttules and a thick gelatinous sheath and botuliform or falciform spermatia with 1-septate or aseptate.

A New Species

Vamsapriya yunnana sp. nov., collected from dead bamboo in Yunnan Province of China, is described and illustrated in this paper. The new taxon is characterized by synnematous conidiophores, with enteroblastic, monotretic conidiogenous cells and brown to dark brown, 4–9-septate, fusiform conidia with a long, apical, appendage-like region. The species differs from the type and other species in the genus in having a wider fertile region and rostrate apex of the conidia. Maximum likelihood and Bayesian inference analyses of a combined ITS, LSU and RPB2 DNA sequence dataset show that V. yunnana is a new species, belonging to the genus Vamsapriya in Xylariaceae.

Phylogenetic relationships within Hesionidae Grube, 1850 are assessed via maximum parsimony and maximum likelihood analyses of mitochondrial (cytochrome c oxidase subunit I and 16S rRNA) and nuclear (18S rRNA, and 28S rRNA) data. The analyses are based on 42 hesionid species; six of these being new species that are described here. The new species, all from deep (>200 m depth) benthic environments (including whale falls) in the eastern Pacific, are Gyptis shannonae, sp. nov., Neogyptis julii, sp. nov., Sirsoe sirikos, sp. nov., Vrijenhoekia ketea, sp. nov., Vrijenhoekia falenothiras, sp. nov., and Vrijenhoekia ahabi, sp. nov. The molecular divergence among the new members of Vrijenhoekia is pronounced enough to consider them cryptic species, even though we cannot distinguish among them morphologically. Our results also showed that the subfamily Hesioninae Grube, 1850, as traditionally delineated, was paraphyletic. We thus restrict Hesioninae to include only Hesionini Grube, 1850 and refer the remaining members to Psamathinae Pleijel, 1998. The present study increases the number of hesionid species associated with whale falls from one to six and markedly increases the number of described deep-sea hesionid taxa. There appear to have been multiple colonisations of the deep sea from shallow waters by hesionids, though further sampling is warranted.

During the investigation of fungal microbiome associated with boxwood in the Czech Republic, samples from Buxus sempervirens L. (Buxaceae) plants were collected and used for isolation. Two fungal strains were proposed as a new species Pyrenochaetopsis kuksensis based on morphology as well as phylogenetic analyses of ITS, LSU, rpb2, and tub2 sequence data. Detailed descriptions and phylogenetic relationships of the new taxon are provided.

Araucaria Araucana

Palicella lueckingii is a newly described corticolous lecideoid lichen from the Malalcahuelo National Reserve growing on the bark of Araucaria araucana in Chile. Detailed morphological studies and inference from molecular phylogenetic analyses, based on maximum likelihood and Bayesian analyses of single gene locus (ITS), clearly indicate that the new species is a member of the recently introduced genus Palicella. Palicella lueckingii is most closely related to P. glaucopa, but clearly differs in having smaller ascospores, comparatively thicker thallus, epruinose apothecia, lack of oil droplets inside of exciple and presence of thiophanic acid as a major metabolite.

Based on traditional morphological and phylogenetic analyses (ITS, LSU, tef-1α and β-tub) of psathyrelloid specimens collected from China, four new species are here described: Heteropsathyrella macrocystidia, Psathyrella amygdalinospora, P. piluliformoides, and P. truncatisporoides. H. macrocystidia forms a distinct lineage and groups together with Cystoagaricus, Kauffmania, and Typhrasa in the /Psathyrella s.l. clade, based on the Maximum Likelihood and Bayesian analyses. Thus, the monospecific genus Heteropsathyrella gen. nov. is introduced for the single species. Detailed descriptions, colour photos, and illustrations are presented in this paper.

ABSTRACT A new species of Curculionichthys is described from the rio Curuá-Una basin, in the northern edge of the Brazilian Shield, State of Pará, Brazil. The new species is diagnosed from congeners by possessing a single rostral plate, by having darkened tooth-crowns, and by a series of morphometric and meristic data. A close examination of the species of Curculionichthys revealed the presence of hyperthrophied odontodes on both dorsal and ventral margins of the snout tip, which are illustrated by electronic microscopy. A discussion is provided on possible phylogenetic relationships of the new taxon. The new species is provisionally accessed as Least Concern (not threatened).

Austropleospora is a genus of Didymosphaeriaceae with only three extant species. A survey of saprobic ascomycetes in Guizhou Province, China, discovered a new Austropleospora species on dead twigs in a terrestrial habitat. The molecular phylogeny based on a combined SSU-LSU-tef1-ITS DNA sequence dataset confirmed the new species’ taxonomic position in Austropleospora. Austropleospora ochracea sp. nov. is characterized by globose to subglobose and uni-loculate ascoma with a centric short papilla, brown to dark brown peridium with cells of textura angularis to textura prismatica and conical, comparatively smaller ascospores with narrowly rounded polar ends. The new taxon is compared with similar species in Austropleospora, and its taxonomic status is briefly discussed.

Laburnicola is a genus in Didymosphaeriaceae that includes saprobic and endophytic fungal taxa. The current study conducted in the subalpine region of Uzbekistan discovered a new species on a dead stem of a wild rose plant. Maximum likelihood and Bayesian analyses of combined LSU, SSU, ITS, and TEF 1-ɑ dataset confirmed the new species’ taxonomic position in Laburnicola. Our new species, Laburnicola zaaminensis (TASM 6152), was clustered with L. dactylidis (MFLUCC 16-0285) with strong bootstrap support. A detailed description together with illustrations are provided for Laburnicola zaaminensis. Furthermore, an annotated species list, a distribution map, and a taxonomic key for Laburnicola species are provided. This is the first record of Laburnicola from Central Asia.

Lower Muschelkalk

A new species of the genusNothosaurusfrom the Lower Muschelkalk of Winterswijk, The Netherlands, shows relatively plesiomorphic features such as a relatively forward position of the pineal foramen. The jugal enters into the ventral margin of the orbit, which would also be regarded as plesiomorphic, were it not that this feature optimizes unequivocally as a reversal and, hence, as a diagnostic (derived) character of the new taxon. The new taxon does not, however, increase the fit of the cladogram for the phylogenetic relationships withinNothosaurusto the stratigraphic record of the genus. The basal position ofNothosaurus juvenilisremains problematic.
