Two new Cortinarius species in subgenus Leprocybe from Southwest China.

ABSTRACT: Two new Cortinarius species in subgenus Leprocybe, Cortinarius hengduanensis and C. yadingensis, are proposed based on a combination of morphological and molecular evidence. Cortinarius hengduanensis has distinct olive tinged basidiomata, a squamulose pileus, and small, subglobose to broadly ellipsoid basidiospores, the ITS sequence differs from that of C. flavifolium by at least 28 substitutions and independent positions. Cortinarius yadingensis has a squamulose pileus and subglobose to broadly ellipsoid coarsely verrucose basidiospores, the ITS sequence has at least 11 substitutions and index position deviations from the other members of the Leprocybe section. Both new species were found in mixed forests of southwest China.

Three new species of Cortinarius subgenus Telamonia (Cortinariaceae, Agaricales) from China.

Project description:Cortinarius is an important ectomycorrhizal genus that forms a symbiotic relationship with certain trees, shrubs and herbs. Recently, we began studying Cortinarius in China and here we describe three new species of Cortinarius subg. Telamonia based on morphological and ecological characteristics, together with phylogenetic analyses. Cortinarius laccariphyllus sp. nov. (section Colymbadini) is associated with broadleaf trees, with strongly hygrophanous basidiomata, special Laccaria-like lamellae and white and extremely sparse universal veil. Cortinarius neotorvus sp. nov. (section Telamonia) is associated with broadleaf trees and is easily confused with C. torvus, but can be distinguished by the colour of the fresh basidiomes and the stipe usually somewhat tapering towards the base. Cortinarius subfuscoperonatus sp. nov. (section Fuscoperonati) is associated with coniferous trees, with subglobose to broadly ellipsoid spores and is closely related to C. fuscoperonatus. A key to the new species and similar species in sections Colymbadini, Telamonia and Fuscoperonati is provided.

Two New Species of Sidera (Hymenochaetales, Basidiomycota) from Southwest China.

Project description:Two new wood-inhabiting fungi, Sidera salmonea sp. Nov. and S. tibetica sp. Nov. in the order Hymenochaetales from southwest China, are described and illustrated based on molecular and morphological evidence. They were found on gymnosperm wood that is rotten and charred. The characteristics of S. salmonea include annual, resupinate basidioma, salmon pores with distinctly white margins, angular pores (7-9 per mm), a dimitic hyphal system, and lunate basidiospores that are 3-3.5 × 0.9-1.1 μm. The characteristics of S. tibetica include annual, resupinate basidioma with a white to cream fresh pore surface that becomes cream to honey-yellow and shiny when dry, round pores (7-8 per mm), a dimitic hyphal system, and lunate basidiospores that measure 2.9-3.1 × 1-1.1 μm. A phylogenetic analysis based on the combined 2-locus dataset (5.8S + nuclear large subunit RNA (nLSU)) shows that the two species are members of the genus Sidera, and they are morphologically compared with related species, respectively. This paper provides a key to the identification of 16 accepted species of Sidera that are found throughout the world.

Two new species of Rhizoplaca (Lecanoraceae) from Southwest China.

Project description:In this study, two new species, Rhizoplacaadpressa Y. Y. Zhang & Li S. Wang and R.auriculata Y. Y. Zhang, Li S. Wang & Printzen, are described from Southwest China, based on their morphology, phylogeny and chemistry. In phylogeny, the two new species are monophyletic, and sister to each other within Rhizoplacachrysoleuca-complex. Rhizoplacaadpressa is characterized by its placodioid and closely adnate thallus, pale green and heavily pruinose upper surface, narrow (ca. 1 mm) and white free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally non-constricted apothecia with orange discs that turn reddish-brown at maturity. Rhizoplacaauriculata is characterized by its squamulose to placodioid thallus, yellowish green and marginally pruinose squamules, wide (1-3 mm) and bluish-black free margin on the lower surface of marginal squamules, the absence of a lower cortex, and its basally constricted apothecia with persistently orange discs. Rhizoplacaadpressa and R.auriculata share the same secondary metabolites of usnic and placodiolic acids.

Two new corticioid species of Phanerochaetaceae (Polyporales, Basidiomycota) from Southwest China.

Project description:Two new corticioid fungi in the family Phanerochaetaceae, Phanerochaete shenghuaii and Rhizochaete variegata, are described and illustrated from Southwest China based on morphological characteristics and molecular data. Phanerochaete shenghuaii is characterized by annual, effused, inseparable basidiocarps from substrate, ivory white to cream hymenial surface when juvenile, buff to yellowish brown with age, buff in KOH, a monomitic hyphal system, smooth cystidia, and ellipsoid basidiospores measuring 4.8-6 × 2.5-3.8 µm. Rhizochaete variegata is characterized by annual, effused, easily separable basidiocarps from substrate, buff-yellow to clay-pink fresh hymenial surface becoming cream to buff upon drying, violet in KOH, a monomitic hyphal system, encrusted cystidia, and ellipsoid basidiospores measuring 3-4 × 2.2-3 µm. The phylogenetic analyses based on ITS + nLSU rDNA sequences confirm the placement of the two new species, respectively, in the Phanerochaete clade and the Rhizochaete clade of Phanerochaetaceae. Phylogenetically related and morphologically similar species to these two new species are discussed.

Two new species of Scytinostroma (Russulales, Basidiomycota) in Southwest China.

Project description:Two new species of Scytinostroma viz. S. acystidiatum and S. macrospermum, are described from southwest China. Phylogeny based on ITS + nLSU dataset demonstrates that samples of the two species form two independent lineages and are different in morphology from the existing species of Scytinostroma. Scytinostroma acystidiatum is characterized by resupinate, coriaceous basidiomata with cream to pale yellow hymenophore, a dimitic hyphal structure with generative hyphae bearing simple septa, the absence of cystidia, and amyloid, broadly ellipsoid basidiospores measuring 4.7-7 × 3.5-4.7 μm. Scytinostroma macrospermum is characterized by resupinate, coriaceous basidiomata with cream to straw yellow hymenophore, a dimitic hyphal structure with generative hyphae bearing simple septa, numerous cystidia embedded or projecting from hymenium, and inamyloid, ellipsoid basidiospores measuring 9-11 × 4.5-5.5 μm. The differences between the new species and morphologically similar and phylogenetically related species are discussed.

Two new species of Boletopsis (Bankeraceae, Thelephorales) from Southwest China.

Project description:Two new species of Boletopsis, B.macrocarpa and B.tibetana, are described and illustrated from Southwest (SW) China based on morphology, ecology and phylogenetic analyses by the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU). Boletopsismacrocarpa is characterized by big basidiocarps (up to 18 cm in diam), guttulate basidiospores, and the presence of gloeoplerous hyphae in context and growing in pure forest of Pinusyunnanensis. Boletopsistibetana is characterized by smaller pores (3-4 per mm), the presence of gloeoplerous hyphae in pileipellis, and the growth in forests of Picea. Phylogenetically, the two new species are grouped in two independent lineages nested in Boletopsis. In addition, one sample from Northeast China is temporarily treated as Boletopsis sp. 1 because of the single sample; another Chinese sample from SW China is sister to B.grisea in phylogeny, and it is treated as B.cf.grisea because the morphological difference between B.cf.grisea and B.grisea is indistinct. Furthermore, the main characteristics of Boletopsis species are listed, and a key to accepted species of Boletopsis is provided.

Two new species of Ganoderma (Ganodermataceae, Basidiomycota) from Southwest China.

Project description:Ganoderma is a large and diverse genus containing fungi that cause white rot to infect a number of plant families. This study describes G.phyllanthicola and G.suae as new species from Southwest China, based on morphological and molecular evidence. Ganodermaphyllanthicola is characterized by dark brown to purplish black pileus surface with dense concentric furrows, pale yellow margin, irregular pileipellis cells, small pores (5-7 per mm) and ellipsoid to sub-globose basidiospores (8.5-10.0 × 6.0-7.5 µm). Ganodermasuae is characterized by reddish brown to oxblood red pileus surface and lead gray to greyish-white pore surface, heterogeneous context, wavy margin and almond-shaped to narrow ellipsoid basidiospores (8.0-10.5 × 5.0-7.0 μm). The phylogeny of Ganoderma is reconstructed with multi-gene sequences: the internal transcribed spacer region (ITS), the large subunit (nrLSU), translation elongation factor 1-α gene (TEF-1α) and the second subunit of RNA polymerase II (RPB2). The results show that G.suae and G.phyllanthicola formed two distinct line-ages within Ganoderma. Descriptions, illustrations and phylogenetic analyses results of the two new species are presented.
