A New Species

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.

Fungal Genus

A new poroid wood-inhabiting fungal genus, Rigidotubus, is proposed to accommodate  R. tephroleucus sp. nov. based on morphological characters and molecular evidence. The genus is characterized by tough and poroid basidiomata, white to grayish white pore surface, white sterile margin, a monomitic hyphal system with clamped generative hyphae, ovoid to ellipsoid basidiospores negative in Melzer’s reagent and Cotton Blue. The phylogenetic analyses inferred from the internal transcribed spacer (ITS) and nuclear large subunit (28S) ribosomal RNA gene regions confirmed that Rigidotubus belongs to Cystostereaceae in Agaricales. A key to the accepted genera of Cystostereaceae is provided.

Sidera is a polypore genus with white to cream or buff basidiomata, whose species in Hymenochaetales are poorly known. We study the phylogeny and diversity of Sidera based on our recent collections from tropic and subtropic Asian-Pacific regions. Phylogenetic analyses based on the internal transcribed spacer (ITS) and nuclear large subunit (nLSU) ribosomal RNA gene regions indicate that ten terminal lineages are well supported within Sidera. Based on morphological examination and phylogeny, four new species, viz. Sidera minutissima, S. parallela, S. srilankensis and S. tenuis are described, and a new combination, Sidera minutipora, is proposed. All these species are illustrated. Sidera minutissima is characterized by tiny basidiomata with bluish pores when fresh, generative hyphae dominating at the dissepiment edges, the presence of cystidioles, and allantoid basidiospores measuring 3.8–4.4 × 0.9–1.3 μm. Sidera parallela differs from other poroid species in the genus by having parallel tramal hyphae in combination with lunate basidiospores measuring 2.8–3.3 × 0.9–1.2 μm. Sidera srilankensis have generative and skeletal hyphae co-dominating at the dissepiment edges, and lunate basidiospores measuring 3.5–4 × 1–1.3 μm. Sidera tenuis is distinguished by small pores (8–10 per mm) and relatively long allantoid basidiospores measuring 4.2–5 × 0.8–1 μm. Sidera minutipora is characterized by buff to olivaceous buff basidiomata when dry, 5–7 pores per mm, rosette-like crystals rare, and allantoid basidiospores measuring 3.7–4.3 × 1–1.3 μm. An identification key to all accepted species is provided.

A New Species

The phylogeny of Amauroderma and related genera were studied using DNA sequences from the internal transcribed spacer (ITS) and 28S nuclear ribosomal RNA gene regions. Amauroderma concentricum sp. nov. is described. The species is characterized by the yellowish brown to reddish brown pileal surface with concentric zones, a white pore surface unchanged when bruised, single to multiple stipes, small pores (4–5 per mm), and subglobose to globose and double-walled basidiospores, 8–9.2 × 7.2–8 µm. The phylogenetic analysis presented here confirmed that Amauroderma as traditionally accepted is not monophyletic.

Based on morphological and molecular data, a new species of Albatrellus sensu stricto, A. alpinus sp. nov., is described from Yunnan Province of southwestern China. Albatrellus alpinus is characterized by a buff to pale yellow pileal surface, simple septate hyphae, yellow and shapeless oily substance present in all hyphae but seldom in tramal hyphae, and small amyloid basidiospores. Phylogenetic analyses based on the nuclear ribosomal internal transcribed spacer (nrITS) and the large subunit of the nuclear ribosomal RNA gene (nLSU) indicated that the new species is nested within Albatrellus sensu stricto. A key to the Chinese species of Albatrellus sensu stricto is provided.

A New 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

A new species of Amanita subgenus Amanita sect. Vaginatae is described and illustrated based on material collected in pine forests in district Mansehra, Khyber Pakhtoonkhaw, Pakistan. Amanita mansehraensis is recognized by the presence of a light brown or light greyish olive pileus with strong brown or deep brown pileus center; non-appendiculate, rimose, sulcate or plicate striate pileus margin; subglobose to ellipsoid basidiospores; and a saccate volva. The internal transcribed spacer region (ITS) and large subunit of the nuclear ribosomal RNA gene (nrLSU) were used for the delimitation of this species based on sequence data. The evolutionary relationships of A. mansehraensis with other species of Amanita were inferred by means of Maximum Likelihood and Bayesian inferences of the nrLSU dataset and concatenated ITS+nrLSU dataset. Amanita mansehraensis is most closely related to A. brunneofuliginea, A. pseudovaginata, and the recently described A. glarea.

Two species of Xanthagaricus discovered in Hubei Province of China are described based on the macro- and micromorphological features. Their identity is further supported by molecular analysis of the internal transcribed spacer (ITS) of the ribosomal RNA gene. The phylogeny obtained here showed that one of the Chinese species is nested in an exclusive clade which in combination with its striking morphological features, infers that it represents a new species, named X. ianthinus, while the other species is placed as a member in the X. epipastus clade. Descriptions are accompanied with illustrations of macro- and micromorphological characters and a discussion of related taxa is presented.

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.

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).
