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).

A New Species

A new species, Calocybe decurrens, is illustrated and described in detail based on morphological characteristics and phylogenetic analyses. Calocybe decurrens is mainly characterized by its decurrent gills and by its stipe that discolors upon maturation. Molecular phylogenetic analyses were based on the internal transcribed spacer (ITS1-5.8S-ITS2) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequences. The results indicated that its affiliation is in genus Calocybe, where it occupies an isolated position. A full description, color images, illustrations and a phylogenetic tree to show the placement of the new species are provided.

Amanita rufobrunnescens is described as a new species in the subgenus Lepidella section Amidella from Guangdong Province, China. It is characterized by whitish basidiomes that bruise reddish brown, brownish sub-membranous to fibrillose volval remnants on the pileus, a striate pileus margin, white lamellae with truncate lamellulae, grayish orange to light brown volva, amyloid basidiospores that are ellipsoid to elongate (9.5–)10–12(–13) × (5–)5.5–6.5(–7) µm, and 5–10 μm wide pileipellis hyphae with yellowish vacuolar pigments. There are no clamp connections. Molecular phylogenetic analyses based on the nuclear ribosomal large subunit of nuclear ribosomal DNA (LSU) and internal transcribed spacer (ITS) sequences reveal that A. rufobrunnescens is a distinct species.

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

A New Species

Russula subsection Amoeninae is morphologically defined by a dry velvety pileus surface, a complete absence of cystidia with heteromorphous contents in all tissues, and spores without amyloid suprahilar spot. Thirty-four species within subsection Amoeninae have been published worldwide. Although most Russula species in South Korea have been assigned European or North American names, recent molecular studies have shown that Russula species from different continents are not conspecific. Therefore, the present study aims to: 1) define which species of Russula subsection Amoeninae occur on each continent using molecular phylogenetic analyses; 2) revise the taxonomy of Korean Amoeninae. The phylogenetic analyses using the internal transcribed spacer (ITS) and multilocus sequences showed that subsection Amoeninae is monophyletic within subgenus Heterophyllidiae section Heterophyllae. A total of 21 Russula subsection Amoeninae species were confirmed from Asia, Australia, Europe, North America, and Central America, and species from different continents formed separate clades. Three species were recognized from South Korea and were clearly separated from the European and North American species. These species are R. bella, also reported from Japan, a new species described herein, Russula orientipurpurea, and a new species undescribed due to insufficient material.

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.

Based on morphological and molecular phylogenetic studies, Semiaquilegia danxiashanensis, a new species from Danxia Shan in northern Guangdong, southern China, is described and illustrated. This species is easily distinguishable from each of other three known species in the genus by characters of the flowers and fruits. In addition, molecular phylogenetic analyses of both the nuclear ITS and the plastid trnL-F region strongly supported S. danxiashanensis as a separate species from other species of Semiaquilegia. We provide a detailed morphological and habitat description, distribution, as well as colour photographs and illustrations of the new species.

A New Species

Tubaria squamata is described as new from Jiaohe county, Jilin province, China. This species is distinctive morphologically because of the small (slightly) hairy or scaly pileus, subelliptic to elliptic non-amyloid basidiospores, subclavate to cylindrical or lageniform cheilocystidia, and a pileipellis as a cutis. Phylogenetic analyses based on internal transcribed spacer sequences with Bayesian Inference analysis (BA) and Maximum Likelihood (ML) showed that T. squamata is different from related species. Illustrations and a complete taxonomic description are also provided, as well as a key to the Tubaria species known from China.

A new species of Fistulina, F. tasmanica sp. nov., is described and illustrated from Tasmania in Australia. Fistulina tasmanica is distinguished by its pileate and fleshy basidiomata with rose pore surface, fibrous context, separated tubes with small pores (6–7 per mm), a monomitic hyphal system with only clamped generative hyphae, subellipsoid to ellipsoid basidiospores (5.4–6 × 3.4–4 μm) which are negative in Melzer’s reagent and cotton blue. Phylogenetic analyses inferred from the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU) sequences also confirmed that F. tasmanica is a new member within Fistulina.

A New Species

Four specimens of Phallus were collected during surveys in a Pinus armandii forest in Baoshan, Yunnan Province, China. Macro- and micro-characteristics, together with Internal Transcribed Spacer (ITS) sequence data, showed that the four specimens belong to a new species, here named Phallus haitangensis. The ITS phylogenetic analyses, morphological descriptions, color photographs, and line drawings are provided, and compared with closely related species in the genus.
