Three new species of Dicephalospora from China as revealed by morphological and molecular evidences.

ABSTRACT: Three new species of Dicephalospora are introduced based on morphological characters and DNA sequence analyses (maximum parsimony and neighbor-joining methods), viz. D.albolutea, D.shennongjiana, and D.yunnanica. All of them lack mucilaginous caps at ascospore poles. Dicephalosporaalbolutea is distinguished by cream to yellowish white apothecia and slightly curved ascospores. Dicephalosporashennongjiana is characterized by yellow apothecia, elliptical-fusoid ascospores 19-22 × 7-8.8 ?m, and J+ asci 130-150 × 14-16.5 ?m. Dicephalosporayunnanica is distinguished by orange apothecia and fusoid ascospores 16.5-25.3 × 3.3-3.5 ?m. Descriptions and illustrations of the new species as well as a key to the known species in the genus are provided.

Three new species of EntolomasubgenusPouzarella from China based on morphological and molecular data.

Project description:In the present paper, three additional species of EntolomasubgenusPouzarella viz. E.erectoides, E.griseocarpum and E.rubropilosum are described from China. E.rubropilosum is a typical species in section Pouzarella; E.griseocarpum and E.erectoides are members of sect. Dysthales. The taxa are further confirmed by ITS, RPB2, LSU and mtSSU analyses and phylogenetic relationships with other Entolomasubgen.Pouzarella species are also discussed. ITS sequence analysis showed that the sizes of the entire ITS region and ITS1 are remarkably divergent, while the ITS2 is conserved in length within Entolomasubgen.Pouzarella. Molecular analyses, based on the combined dataset, demonstrated that species diversity of subgen.Pouzarella in China is much higher than previously thought, in the present study twenty phylogenetic species from China are taken into consideration. On the other hand, morphological and molecular analyses suggested that classification of Entolomasubgen.Pouzarella probably has to be fundamentally re-adjusted based on additional data.

Morphological Characters and Molecular Phylogeny Reveal Three New Species of Subgenus Russula from China.

Project description:Three new species are described and illustrated here based on morphological evidence and phylogenetic analysis from China. Russula leucomarginata is recognized by a yellowish red to reddish brown pileus center, a yellowish white to reddish white and sometimes cracked margin, and a reddish white to pastel pink stipe. Russula roseola is characterized by its reddish white to ruby red pileus center, pink to rose margin, adnate to slightly decurrent lamellae with unequal-length lamellulae, reddish white to pink stipe, and occasionally three-celled pileocystidia. Russula subsanguinaria is morphologically characterized by a reddish brown to dark brown pileus center, a reddish orange to brownish red margin with striation, a reddish white to pink stipe with an expanded base, basidiospores with moderately distant to dense amyloid warts, and hymenial cystidia turning to reddish black in SV. In this study, we performed phylogenetic analysis based on ITS sequence and 28S-RPB1-RPB2-mtSSU datasets. Detailed morphological features and phylogenetic analysis indicate that these three new species belong to Russula subg. Russula.

Hydnaceous fungi of China 8. Morphological and molecular identification of three new species of Sarcodon and a new record from southwest China.

Project description:Three new stipitate hydnoid fungi, Sarcodon coactus, S. grosselepidotus and S. lidongensis, are described and illustrated, based on morphological characteristics and nuc ITS rDNA + nuc LSU rDNA sequence analyses and a new record, S. leucopus, from China is reported. S. coactus is characterised by ellipsoid to round basidiocarps, reddish-brown to dark brown, felted pileal surface with white and incurved margins, simple-septate and partly short-celled generative hyphae and irregular subglobose, thin-walled, brown basidiospores with tuberculate ornamentation (tuberculi up to 1 μm long). S. grosselepidotus is characterised by infundibuliform to round, occasionally deeply fissured pileus, pale orange to dark ruby pileal surface with ascending and coarse scales, simple-septate generative hyphae and irregular ellipsoid to globose, thin-walled, brown basidiospores with tuberculate ornamentation (tuberculi up to 0.7 μm long). S. lidongensis is characterised by plano-convex to somewhat depressed and regular orbicular pileus, light brown to dark brown pileal surface with adhering squamose and purplish-brown, incurved and occasionally incised margin, cylindrical or broadened below stipe, simple-septate generative hyphae and irregular ellipsoid to subglobose, thin-walled basidiospores with tuberculate ornamentation (tuberculi up to 1 μm long). The absence of the clamp connection is the common morphological characteristic of these three new species; however, S. leucopus, a new record from China, has frequently clamped generative hyphae. Molecular analyses confirm the phylogenetic positions of three new and the new record species. The discriminating characters of these three new species and closely related species are discussed and a key to the species of Sarcodon from China is provided.

Morphological characteristics and phylogenetic analyses revealed four new species of Agaricales from China.

Project description:Four new species of Agaricales from China viz. Hohenbuehelia tomentosa, Rhodophana qinghaiensis, Rhodophana aershanensis, and Spodocybe tomentosum are described based on their unique morphological features and molecular evidence. Hohenbuehelia tomentosa is mainly characterized by its dark brown pileus with finely dense pure white tomentum, dirty white, decurrent lamellae, eccentric stipe, smooth spores, and fusiform metuloid cystidia. The characteristics of Rhodophana qinghaiensis are glabrous, smooth, reddish-brown pileus, gray-orange lamellae, and initially light orange becoming reddish brown stipe. The unique morphological characteristics of Rhodophana aershanensis are reddish brown pileus with age, brown-orange toward the margin, light orange lamellae and stipe dark brown at first, and reddish-brown with age. Spodocybe tomentosum is characterized by subclitocyboid and small basidiomes, finely dense pure white tomentum on the pileus surface, and broadly ellipsoid to ellipsoid and smaller basidiospores. Phylogenetic analysis showed that Hohenbuehelia tomentosa, Rhodophana qinghaiensis, Rhodophana aershanensis, and Spodocybe tomentosum formed an independent lineage. Full descriptions, illustrations, and phylogenetic trees of the four new species are provided in this study.

Three new Melanoleuca species (Agaricales, Basidiomycota) from north-eastern China, supported by morphological and molecular data.

Project description:Three new Melanoleuca species, M. chifengense, M. griseoflava and M. pallidorosea, were discovered in the northeast of China. Melanoleuca chifengense is morphologically characterised by its grey to yellowish-grey pileus, decurrent lamellae, grey to yellowish-brown stipe, yellowish-grey context, ellipsoid basidiospores with irregular warts and lack of hymenial cystidia. Melanoleuca griseoflava is mainly characterised by its greyish-brown pileus, adnexed to adnate lamellae, greyish-yellow context, fusiform cystidia and almost reticulate basidiospores. Melanoleuca pallidorosea is characterised by its pinkish-white pileus, white and decurrent lamellae, ellipsoid basidiospores with round and scattered warts and lack of hymenial cystidia. The phylogenetic relationship of the three species was determined by the analyses of the ITS region and the combined data matrix (ITS-nrLSU-RPB2), respectively. The results showed that the three species formed three independent lineages. Based on the combination of both morphological and molecular data, M. chifengense, M. griseoflava and M. pallidorosea were confirmed to be new species. The morphological similarities of the three new species is also discussed.

Distribution of Holttumochloa (Poaceae: Bambusoideae) in China with description of a new species revealed by morphological and molecular evidence.

Project description:Holttumochloa has previously only been recorded from Malaysia. Here we describe and illustrate a new species, Holttumochloa hainanensis sp. nov., from the lowland montane forests of Diaoluo Mountain on the Island of Hainan, South China. Morphologically, H. hainanensis is similar to Holttumochloa korbuensis, but can be clearly distinguished from it in having larger culms covered by white wax, longer leaf blades, larger pseudospikelets and anthers. Furthermore, molecular phylogeny based on the nuclear gene GBSSI corroborates the identification of the new species and its affinity. The biogeographical significance of the new record of Holttumochloa in South China is also highlighted in this study.

New Species and New Records of Otidea from China Based on Molecular and Morphological Data.

Project description:Species of genus Otidea previously reported in China are mainly distributed in the northeast, northwest and southwest regions of China, but the species diversity of Otidea in north China is not very clear. In this study, newly collected Otidea specimens from northern China and some herbarium specimens deposited in three important Chinese fungus herbaria (HMAS, HKAS, HMJAU) were studied using morphological and phylogenetic methods. The internal transcribed spacers of the nrDNA (ITS), the nrRNA 28S subunit (nrLSU), the translation elongation factor 1-alpha (tef1-α), and the second largest subunit of RNA polymerase II (rpb2), were employed to elucidate the phylogenetic relationships between Otidea species. Results identified 16 species of Otidea, of which seven new species are described, namely O.aspera, O.cupulata, O. filiformis, O.khakicolorata, O. parvula, O.plicara and O.purpureobrunnea. Otidea bicolor and O. pruinosa are synonymized as O. subpurpurea. Two species, O. mirabilis and O. nannfeldtii, are being reported for the first time in China. The occurrence of O. bufonia, O. leporina and O. onotica are confirmed by molecular data in China.
