A New Species

A new species of Gymnopus sect. Androsacei, namely, G. pallipes is described and illustrated based on morphological and molecular phylogenetic evidence. It is characterized by marasmioid basidiomata, a dark brown to reddish brown pileus becoming dull white to yellowish grey with age, whitish to pale yellow stipe and presence of rhizomorphs. Phylogenetic analyses support it as a new species within Gymnopus sect. Androsacei. The detailed morphological description, colour photos of basidiomata, and line drawings of microcharacters are presented and delimitation characters from similar species are discussed. A key to the known species of Gymnopus s. str. from China is also provided.

A new species of Afroboletus, namely A. sequestratus, is described from Zambia. Evidence from molecular phylogenetic analyses using sequences rpb1, rpb2 and tef1α and morphological comparison support its placement in Afroboletus and it is distinct from the other related members of this genus in Africa. It is the first species with sequestrate basidiomata in the genus. A morphological description is augmented with line drawings and SEM images for the species.

A New Species

Euphorbia motuogensis M. T. Li, X. Z. Lan, H. P. Deng & W. L. Zheng, sp. nov., a new species from Motuo, Tibet, China, is described and illustrated here. It is closely similar to Euphorbia sikkimensis in having terete root, alternate leaves, well-developed pseudoumbellate inflorescence, cyathium, smooth and glaborus capsule, but Euphorbia motuogensis is clealy distinguishable by its pilose stems, involucral leaves color, secondary involucral leaves absent, cyathophylls number and color, and five similar glands. Furthermore, molecular phylogenetic analyses of sequences from both nuclear ribosomal ITS confirm that this species is distinct from morphologically similar species in this subgenus.

During this investigation, a new species of Melanoleuca subg. Urticocystis with urticiform cheilocystidia is proposed. The identification is based on morphological characters and molecular phylogenetic analyses using ITS and 28S sequences. A comparison of the morphological features and molecular phylogenetic data with the taxa of subg. Urticocystis confirms the identity of the species as a new taxon. The detailed descriptions, line drawings and phylogenetic results are given.

Gerhardtia sinensis, as a new species discovered from southern China, is described, illustrated and compared with morphologically similar and phylogenetically related species. Morphologically, it is characterized by its white to yellowish or partially pale yellow pileus with faint striae, subdistant to fairly distant lamellae with intervenose veins, and slightly verruculose basidiospores (4.7–)5.2–6.2(–6.6) × (2.5–)3.0–3.4(–3.8) μm in size. Molecular phylogenetic analyses of the new species and related taxa are performed based on the sequences of nuclear ribosomal large subunit (nrLSU) and nuclear ribosomal internal transcribed spacer (ITS).

Russula darjeelingensis is characterized by its small sized white pileus with a tall and narrow stipe, white spore print, basidiospores with amyloid suprahilar spot and a pileipellis containing encrusted pileocystidia and absence of primordial hyphae. The combination of all these characters and molecular phylogenetic analyses of internal transcribed spacer sequences of nuclear ribosomal DNA confirmed it as a new species in genus Russula Pers., subg. Russula Romagn. emend. sect. Polychromae (Maire) Sarnari subsect. Paraintegrinae Sarnari. A comprehensive morphological description, illustrations, and comparisons with morphologically similar and phylogenetically related species are provided in the present study.

A new species of Peronosporales: Phytopythium nanjingense, isolated from the lake water of Nanjing in Jiangsu Province of China is described and illustrated based on morphological characters and supported by molecular phylogenetic analyses using ITS rDNA and Cox1 and Cox2 mtDNA sequences. Phytopythium nanjingense is heterothallic and characterized by aquatic habitat, ellipsoid, mostly obpyriform to ovoid-obpyriform, internally or internally nested proliferating sporangia with conspicuous apical papillae, smooth oogonia, hypogynous antheridia, filamentous antheridial cells, and plerotic or nearly plerotic and thin-walled oospores (0.5–1.6 µm). Differences between the new species and phylogenetically related and morphologically similar species are discussed.
