Karst Habitats

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

Two New Species

Two new species of Dentipellis are described from China based on morphological characteristics and molecular data. Dentipellis longiuscula is characterized by annual, resupinate hydnoid basidiomata with moderately long spines, rough basidiospores (5–6 × 3–3.6 µm) and absence of gloeoplerous hyphae and gloeocystidia. Dentipellis tropicalis is characterized by hydnoid basidiomata with numerous gloeocystidia presenting in hymenium, and minutely rough basidiospores (5–5.5 × 2.5–3.2 µm). Phylogenetic analysis based on the internal transcribed spacer (ITS) and nuclear large subunit ribosomal (nLSU) RNA gene regions confirmed the affinity of the new species in Dentipellis and indicated their relationships with other species in the genus.

A New Species

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Two new species of Tomentella from the Lesser Xingan Mts. of northeastern China, T. pallidocastanea and T. tenuirhizomorpha, are described and illustrated using morphological characteristics and molecular phylogenetic analysis. T. pallidocastanea is characterized by mucedinoid basidiocarps adherent to the substrate, a light reddish brown to pinkish grey hymenophoral surface, absence of rhizomorphs and cystidia, generative hyphae with clamps, rarely with simple septa and echinulate, and subglobose to lobed basidiospores (echinuli up to 1.5 μm long). T. tenuirhizomorpha is characterized by mucedinoid basidiocarps separable from the substrate, a greyish brown to dark brown hymenophoral surface, thin rhizomorphs in the subiculum and margins, an absence of cystidia, generative hyphae with clamps rarely with simple septa and echinulate, and subglobose to globose basidiospores (echinuli up to 1.5 μm long). Molecular analyses using Maximum Likelihood, Maximum Parsimony and Bayesian Analysis confirm the phylogenetic position of the two new species. The discriminating characters of these two new species and their closely related species are discussed in this study.

Three new species of Calocybella, C. lohitha, C. babruka and C. swetha are described from Kerala State, India based on morphology and molecular phylogeny. Comprehensive descriptions of these species are provided along with photo-illustrations and comparisons with phenetically similar and phylogenetically related species. Nuclear ribosomal internal transcribed spacer (ITS) region of the three species were sequenced and analyzed. In addition, nuclear ribosomal large subunit (nrLSU) region of Calocybella swetha was sequenced and used in BLASTn search to find similar sequences. ITS-based phylogenetic analysis using Maximum likelihood (ML) method supported both the novelty of these species and their placement within the genus. The discovery of these three species forms the first record of Calocybella outside Europe.

A New Species

A new species of Polyporales, named as Skeletocutis yunnanensis, was collected on angiosperm wood in northern Yunnan Province, southwestern China. It is described based on morphological characteristics and molecular evidence. The species belongs to the Skeletocutis subincarnata complex, but differs morphologically from all known species of the genus by white, cream to buff pores surface, angular pores mostly 5–6 per mm with entire mouths, a dimitic hyphal structure both in trama and subiculum, generative hyphae in whole basidiocarps covered by fine crystals, skeletal hyphae unchanged in KOH, not agglutinated, allantoid basidiospores measured as 3.5–4.5 × 1.0–1.2 µm, and growth on angiosperm wood. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the new species grouped with Skeletocutis and nested in the tyromyces clade.

Two fresh collections of Discosia were made from dead leaves of Fagus sylvatica in Italy. As these collections could not be cultured, the fruiting bodies were directly used for sequencing using a Forensic DNA Extraction Kit. Based on analyses of the concatenated internal transcribed spacer regions of the nrDNA operon (ITS) and large subunit rDNA (LSU) gene sequences, as well as morphological characters, the fresh collections are introduced as two new species, namely D. italica and D. fagi. Phylogenetically, these two species are distinct from all other Discosia species. Morphologically, D. italica is somewhat similar with D. fagi, but can be distinguished using dimension of conidiomata and conidiogenous cells. Descriptions and illustrations of the new taxa are provided herein.

Two New Species

Gyroporus species with cyanescent oxidation reactions were investigated, based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU), the nuclear ribosomal internal transcribed spacer (ITS) and the mitochondrial adenosine triphosphate ATP synthase subunit 6 (atp6). Three species, including two new species, namely G. alpinus and G. flavocyanescens and one previously-described species, namely G. brunneofloccosus, are revealed from China. Collections formerly reported from China as “G. cyanescens” are either G. alpinus or G. flavocyanescens. The new species are documented and illustrated in detail, while the concept of G. brunneofloccosus is refined with additional recently-collected materials. Additionally, the cyanescent species G. pseudomicrosporus, previously described from China, is shown to be a member of the genus Gyrodon, based on re-examination of the type specimen. A key to the cyanescent Gyroporus species from China is provided.

Phoma odoratissimi sp. nov. on Viburnum odoratissimum and Syringa oblate, and Phoma segeticola sp. nov. on Cirsium segetum from China are introduced and described, employing a polyphasic approach characterising morphological characteristics, host association and phylogeny. Both species are the first records of Phoma species on their respective hosts. Multi-locus phylogenetic tree was inferred using combined sequences of the internal transcribed spacer regions 1 & 2 and 5.8S nrDNA (ITS), and partial large subunit 28S nrDNA region (LSU), β-tubulin (TUB) region and RNA polymerase II (RPB2) region. The two new species clustered in two separate and distinct lineages, and are distinct from their allied species.
