A New Species

A novel species, Pogostemon monticola (Lamiaceae; Lamioideae), is described from Taiwan. Phylogenetic analysis based on nuclear ITS and five cpDNA regions supports its monophyletic status and a close relationship with P. amaranthoides, P. chinensis, P. formosanus and P. septentrionalis. Detailed morphological comparison between the new species and the four closely related taxa is presented.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

Mahonia lancasteri (Berberidaceae) is described from cultivation as a new species from west-central Sichuan, China. A detailed description, distributional data and ecological information along with color photographs are provided. In addition, a comparison of M. lancasteri with morphologically similar species, as well as information about its introduction and history in cultivation, is presented. We also performed a phylogenetic analysis using five molecular loci (nuclear ITS, accD, ndhF, rbcL and psbA-trnH) to further determine the close affinities of M. lancasteri. The new species naturally occurs in sympatry with several other Mahonia species.

Molecular phylogenetic analysis based on nuclear ITS well supports its belonging to Tetrataenium sensu stricto. The new species can be easily distinguished by its unique peltate, palmatilobate basal and lower leaves from the other five Chinese Tetrataenium species.

A new species of Cymbidium (Orchidaceae), Cymbidium biflorens, from Yunnan Province, China, is illustrated and described based on morphological and molecular evidence. Morphological comparison indicates that C. biflorens is similar to C. rhizomatosum, but differs by its leafless, coralline rhizome, normally two flowering periods, a shorter scape, inflorescence with 1–2 flowers, greenish flowers with longer pedicel and ovary, subelliptic petal, petals and lip not fully opened. Molecular analyses base on nuclear (ITS) and plastid DNA (matK and rbcL) were conducted to explore the phylogenetic position of the species. The molecular evidence supports C. biflorens as sister to C. rhizomatosum.

A new species of Corynesporopsis from rotting wood of Acacia confusa differs from similar species with one-septate conidia by comparatively short conidiophores and conidia and deeper brown pigmentation of conidiogenous cells than of more proximal cells of the conidiophore. Morphology in culture differs from that in situ mainly by hyaline vegetative hyphae and branched conidiophores. A phylogenetic analysis including a species of Corynesporopsis indicates a close relationship to Xylariales and the occurrence of tretic conidiogenesis in this order. Corynesporopsis quercicola is a new record for Taiwan.

Dimeropyge öpik, 1937, is a genus currently composed of at least 14 similar Middle (predominantly) to possibly lowest Upper Ordovician species from Laurentia (13 species) and Baltica (one species). Possible Lower Ordovician specimens have been illustrated by Ross (1951). Dimeropyge clintonensis Shaw, 1968, is redescribed, based upon additional material of mature topotypes. A new species of Dimeropyge, D. speyeri, is proposed for material from the Esbataottine Formation in the Mackenzie Mountains, northwestern Canada, previously described as D. clintonensis. A phylogenetic analysis of 10 of the 14 species of this genus is presented (the other species are less completely known, and are related to the analyzed species in a more traditional manner). Ontogenies from protaspid to holaspid stages are provided for D. clintonensis, D. speyeri, and D. virginiensis Whittington and Evitt, 1954. The larval stages of these species are very similar, supporting the close relationship between species assigned to Dimeropyge.

A new species, Aureobasidium khasianum, was found growing on decaying leaves of Wightia speciosissima (Paulowniaceae) in India. It is described here with newly observed morphological features such as formation of setae having adhering conidiogenous cells and producing monilioid conidia. A phylogenetic analysis based on ITS and LSU gene regions is provided to support the taxonomic treatment.

Paris polyphylla is an important perennial medicinal plant in China. A disease similar to gray mold on P. polyphylla occurred at the seedling stage in March 2016 and 2017 in Tengchong city, Yunnan Province of China. The disease resulted in up to 50% mortality in serious cases. Isolates from diseased plants grew 10.6 mm/day at 20°C on PDA. After 21 days, sclerotia were spherical to elliptical (0.4–2.5 × 0.3–1.8 mm). Conidia from diseased tissues were hyaline to pale brown, long, ovoid, unicellular, and measured 15.1–24.5 × 8.8–13.4 μm; conidiophores were 526–1,064 ×12–15 μm. Isolates did not form conidiophores or conidia on PDA or MYA. A phylogenetic analysis based on G3PDH, RPB2, and HSP60 sequence data supported assignment of three representative isolates as a new species of Botrytis. Based on morphological, phylogenetic characteristics and Koch’s Postulates, the causal agent of gray mold on P. polyphylla was identified as a novel species, Botrytis polyphyllae.

A New Species

During an investigation of micro-fungi inhabiting mangrove forests, a new species of Rhytidhysteron was collected and isolated from dead twigs of a mangrove tree. Rhytidhysteron mangrovei sp. nov. is introduced, described, illustrated and compared with accepted species in the genus. Morphological comparison based on the size of exciple, the appearance of ascomata and ascospore septations and size as well as the multi-gene phylogenetic analyses based on LSU, ITS and TEF DNA sequences support its establishment in Rhytidhysteron. Placement of the genus in Hysteriaceae is also well-supported. In addition, phylogenetic analysis and DNA sequence data indicate that Rhytidhysteron mangrovei is closely related to Rhytidhysteron thailandicum. However, R. mangrovei is morphologically distinct from R. thailandicum, by having a relatively smaller size of exciple and perpendicularly rough-striate ascomata.
