Abstract Two new taxa of Russula from the Dinghu Mountain, Guangdong Province, China were described and illustrated based on both morphological data and phylogenetic analysis of the internal transcribed spacer sequences. Russula dinghuensis is characterized by the olive green pileus, acute and incurved margin, white and rarely forked lamellae, white spore print, globose to ellipsoid basidiospores with stocky and isolated warts, thick metachromatic pileipellis, and slender, furcated and septated terminal elements of pileipellis. Russula subpallidirosea is recognized by the pale pink to pale grayish-pink pileus, white and forked lamellae, white spore print, subglobose to ellipsoid basidiospores with the isolated, subcylindrical to conical warts, the metachromatic pileipellis, and the short, furcated and septate terminal elements of pileipellis. Both molecular and morphological analyses consistently confirm that these two new taxa are placed into Russula subg. Heterophyllidia subsection Cyanoxanthinae. The morphological differences among these two novel species and the closely related taxa are discussed.

Abstract The family Gloniaceae is represented by the genera Glonium (plant saprobes) and Cenococcum (ectomycorrhizae). This work adds to the knowledge of the family, by introducing a new taxon from dead scales of pine cones collected on the ground in Chiang Mai Province, Thailand. Analysis of a combined LSU, SSU, RPB2 and TEF1 sequence dataset matrix placed it in Gloniaceae and Purpurepithecium murisporum gen. et sp. nov. is introduced to accommodate the new taxon. The genus is characterized by erumpent to superficial, navicular hysterothecia, with a prominent longitudinal slit, branched pseudoparaphyses in a gel matrix, with a purple pigmented epithecium, hyaline to dark brown muriform ascospores and a Psiloglonium stygium-like asexual morph which is produced in culture. The new taxon is illustrated and compared with similar genera.
Gloniaceae是由Glonium属(植物样本)和cenococum属(外生菌根)所代表的。这项工作通过从泰国清迈省地面收集的死松果鳞片中引入一个新的分类群，增加了对这个科的认识。通过LSU、SSU、RPB2和TEF1序列数据集矩阵分析，将其定位于Gloniaceae和Purpurepithecium murisporum gen. et sp. 11。该属的特征为:蛇形至浅表的舟状子宫膜，有明显的纵向狭缝，凝胶基质中的分枝性假脊膜，紫色着色的上皮，透明到深棕色的分形子囊孢子，培养中产生的类似茎鞘的无性形态的Psiloglonium。对新分类单元进行了图解，并与相似属进行了比较。

Abstract Three new species, Aleurodiscus dextrinoideophyses, A. thailandicus and A. verrucosporus, on bamboos are described and illustrated based on morphological and molecular evidence. Aleurodiscus dextrinoideophyses and A. thailandicus, collected from northern Thailand, possess abundant acanthophyses and small smooth basidiospores, and belong to the A. cerussatus group. While A. dextrinoideophyses is characterized by the dextrinoid acanthophyses, A. thailandicus has yellow acanthophyses arranged between subhymenium and basal layer. Aleurodiscus verrucosporus, collected from Fujian Province, southeastern China, is distinguished by the absence of acanthophyses and verrucose basidiospores. All the three species have abundant gloeocystidia and simple-septate generative hyphae. The phylogeny of taxa in Stereaceae was inferred from the combined ITS and nrLSU sequence data. In our phylogenetic analyses, A. dextrinoideophyses and A. thailandicus steadily nested within the A. cerussatus group, whereas A. verrucosporus clustered with different taxa in maximum parsimony and Bayesian analyses.

Abstract Rhizochaete is a small genus of crust fungi that is closely related to Phanerochaete. A new species Rhizochaete belizensis is described, and three new combinations are proposed. Morphological studies and molecular sequence data from two nuclear ribosomal DNA regions (ITS and LSU) support the recognition of R. belizensis which is closely related to R. radicata. Analyses of sequence data also support the transfer of Phanerochaete flava to Rhizochaete. Phanerochaete percitrina from Cameroon and Peniophora rhizomorpho-sulphurea from India are transferred to Rhizochaete based on morphological studies of type specimens. Phanerochaete rubescens from Taiwan is placed in synonymy under R. borneensis. In addition, Phanerochaete mauiensis is redescribed and illustrated. A key to 13 accepted species of Rhizochaete and three morphologically similar species is presented.

Abstract A new species of Kirschsteiniothelia from dead branches of sessile oak, K. arasbaranica, is described from Arasbaran forests of Iran, using morphological and molecular data. Kirschsteiniothelia arasbaranica, lacking an anamorph, is characterized by possessing eight-spored, cylindrical-clavate, bitunicate, fissitunicate asci, 120-180 × 30-40 µm, with an apical ocular chamber 5–8 µm wide, and ascospores narrowly to broadly ellipsoidal, 1-septate, verrucose to finely spinulose, (30-)34-42(-44) × (12-)13-16(-18) µm, with a distinct mucilaginous sheath. Phylogenetic analysis of a combined sequence dataset of the ITS, LSU and SSU rDNA also supports the recognition of this fungus as a new species. We hereby propose an emendation of the family Kirschsteiniotheliaceae. A dichotomous key for identification of 20 sufficiently documented Kirschsteiniothelia species is also provided.

Abstract Water-filled tree holes (dendrotelmata) are mostly ephemeral micro-ecosystems characterized by high level of heterotrophic microbial activity sustained by allochthonous organic matter. In this paper, description of a five-year long observation of fungal consortia in a Norway maple tree-hole is presented. Overall, 139 fungal taxa were detected. Among them, Excipularia fusispora, Ellisembia leptospora, Rebentischia unicaudata, Tricladium castaneicola, Thielavia terricola and Alternaria spp. occurred most frequently. Our observations suggest that even an individual dendrotelma represents an exceptional microhabitat, forming a hot-spot for microfungi due to its role as a natural spore trap and its (temporarily) aquatic environment. Our results show that this aquatic micro-ecosystem supports highly diverse mycobiota with continuous temporal dynamics, with an important fraction of sporadic taxa.

Abstract The diversity of lignicolous freshwater fungi along a north-south latitudinal gradient are currently being studied in Asia. In this paper, we report on 18 collections of asexual morphs of Tubeufiaceae from submerged wood in rivers, streams and a lake in Yunnan Province, China. Taxa are characterized based on morphological characters and analyses of ITS, LSU and TEF1α sequence data. The new genera, Muripulchra with a single species, M. aquatica and Neohelicomyces with three new taxa (N. aquaticus, N. grandisporus, N. submersus) are introduced. Muripulchra is characterized by micronematous conidiophores and obpyriform, septate to muriform conidia. Neohelicomyces is characterized macronematous conidiophores and multi-septate, helicoid conidia. Tubeufia aquatica is introduced as a new species and its phylogenetic relationships with other taxa is discussed. The phylogenetic analyses of a concatenated ITS, LSU and TEF1α dataset place all collections in the family Tubeufiaceae (Tubeufiales) and provide evidence to support the establishment of our new taxa. The asexual morph of Tubeufia cylindrothecia, the type species of Helicomyces (H. roseus) are described herein, phylogenetic relationships assessed and reference specimens are given for these two species. Descriptions and illustrations for the new genera and species are provided with notes on their taxonomy and phylogeny.

Abstract This paper contributes to studies on the lichen biota of Arctic glacier forelands. The research was carried out in the moraines of three different glaciers in Svalbard: Longyearbreen, Irenebreen and Rieperbreen. In total, 132 lichen taxa and three lichenicolous lichens were recorded. Eight species were recorded for the first time in the Svalbard archipelago: Arthonia gelidae, Buellia elegans, Caloplaca lactea, Cryptodiscus pallidus, Fuscidea kochiana, Merismatium deminutum, Physconia distorta, and Polyblastia schaereriana. One species, Staurothele arctica, was observed for the first time in Spitsbergen (previously recorded only on Hopen island). All the studied glaciers lie in Spitsbergen's warm region. However, Kaffiøyra Plain, where Irenebreen is located, is characterized by higher levels of humidity, which may explain its different lichen composition compared to that of the other two moraines. The forelands of Rieperbreen and Longyearbreen are located in the same area of Svalbard, which is also the warmest and the driest and where high species diversity is expected. This proved to be true for the Rieperbreen moraine, but not for the Longyearbreen moraine, where species diversity was lowest. The expansion of tourism along Longyearbyen appears to be a major factor behind the poor development of lichen biota on the Longyearbreen moraine.
