Three New Species

Nine species of Dichostereum were subjected to phylogenetic analyses, based on a combined dataset of ITS1-5.8S-ITS2-nrLSU-tef1 sequences. The morphology of specimens collected from China and Australia were studied. Three species, D.austrosinense, D.boidinii and D.eburneum, collected from southern China, are described and illustrated as new to science, based on the morphological and molecular evidence. Dichostereumaustrosinense is characterised by the relatively large gloeocystidia (80–130 × 8–15 µm) and basidiospores (7.3–8 µm in diam.) with large warts and crests. Dichostereumboidinii is distinguished by its thick basidiomata and relatively small basidiospores (5.5–6.5 µm in diam.) with large warts and crests. Dichostereumeburneum is unique in having pale basidiomata growing on bark of living Castanopsis, abundant crystals in the context and basidiospores with dense and large ornamentations. A key to the 5 species of Dichostereum in China is given.

Three wood-inhabiting fungal species, Xylodon gossypinus, X. macrosporus, and X. sinensis spp. nov. were collected from southern China, with the similar function to decompose rotten wood, which are here proposed as new taxa based on a combination of morphological features and molecular evidence. Xylodon gossypinus is characterized by the resupinate basidiomata with cotton hymenophore, and ellipsoid basidiospores; X. macrosporus is characterized by the resupinate basidiomata having the cracking hymenophore with pale yellowish hymenial surface, and larger basidiospores 8–10.5 × 7.5–9 µm; and X. sinensis differs by its grandinioid hymenial surface and subglobose basidiospores measuring as 3–5 × 2.5–4 µm. Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis in Hymenochaetales revealed that the three new species clustered into the Schizoporaceae family, located in genus Xylodon; based on the ITS dataset, X. gossypinus was a sister to X. ussuriensis; X. macrosporus closely grouped with X. follis with a high support; and X. sinensis was retrieved as two sisters to X. attenuatus and X. yarraensis with a lower support.

Three wood-inhabiting fungal species, Xylodon laceratus, X. montanus, and X. tropicus spp. nov., were collected from southern China, here proposed as new taxa based on a combination of morphological features and molecular evidence. Xylodon laceratus is characterized by the resupinate basidiomata with grandinioid hymenophore having cracked hymenial surface, and ellipsoid basidiospores; X. montanus is characterized by the annual basidiomata having the hard, brittle hymenophore with cream hymenial surface, and ellipsoid to broadly ellipsoid basidiospores (3.9–5.3 × 3.2–4.3 µm); and X. tropicus is characterized by its grandinioid hymenophore with buff to a pale brown hymenial surface and subglobose basidiospores measuring 2–4.8 × 1.6–4 µm. Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis of the order Hymenochaetales indicated that the three new species clustered into the family Schizoporaceae, located in genus Xylodon; based on further analysis of ITS dataset, X. laceratus was a sister to X. heterocystidiatus; X. montanus closely grouped with X. subclavatus and X. xinpingensis with high support; while X. tropicus was retrieved as a sister to X. hastifer.

Three New Species

Three new species of Russula collected from southern China are proposed based on morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Russula bubalina sp. nov. is characterized by cinnamon buff to pink pileus with striate margin, interveined and forked lamellae, basidiospores with warty ornamentations not forming reticulum, hymenial cystidia becoming brown in sulphovanillin (SV) and slender terminal cells in suprapellis. R. pseudobubalina sp. nov. is closely related to Russula bubalina in macro-morphology, but it can be recognized by its unforked lamellae, shorter cheilocystidia, bigger basidia and basidiospores with lower ornamentations. Russula subatropurpurea sp. nov. can be recognized by the purplish brown pileus, mild-tasted and white context changing to light purplish red with FeSO4, white and forking lamellae without lamellulae, long hymenial cystidia becoming brown in SV. Both morphological and phylogenetic analysis consistently confirmed the distinct positions of three new species in subg. Heterophyllidia subsection Heterophyllinae.

Wood-inhabiting fungi play crucial roles as decomposers in forest ecosystems and, in this study, two new wood-inhabiting corticioid fungi, Hyphoderma puerense and H. tenuissimumspp. nov., are proposed, based on a combination of morphological features and molecular evidence. Hyphoderma puerense is characterised by effused basidiomata with smooth to floccose hymenial surface, a monomitic hyphal system with clamped generative hyphae and ellipsoid basidiospores. Hyphoderma tenuissimum is characterised by resupinate basidiomata with tuberculate to minutely-grandinioid hymenial surface, septate cystidia and cylindrical to allantoid basidiospores. Sequences of ITS and nLSU rRNA markers of the studied samples were generated and phylogenetic analyses were performed with Maximum Likelihood, maximum parsimony and Bayesian Inference methods. These analyses showed that the two new species clustered into Hyphoderma, in which H. puerense grouped with H. moniliforme and H. tenuissimum formed a singleton lineage. In addition, an identification key to Chinese Hyphoderma is provided.

Three new wood-inhabiting fungi, Hyphoderma crystallinum, H. membranaceum, and H. microporoides spp. nov., are proposed based on a combination of morphological features and molecular evidence. Hyphoderma crystallinum is characterized by the resupinate basidiomata with smooth hymenial surface scattering scattered nubby crystals, a monomitic hyphal system with clamped generative hyphae, and numerous encrusted cystidia present. Hyphoderma membranaceum is characterized by the resupinate basidiomata with tuberculate hymenial surface, presence of the moniliform cystidia, and ellipsoid to cylindrical basidiospores. Hyphoderma microporoides is characterized by the resupinate, cottony basidiomata distributing the scattered pinholes visible using hand lens on the hymenial surface, presence of halocystidia, and cylindrical to allantoid basidiospores. Sequences of ITS+nLSU rRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. These phylogenetic analyses showed that three new species clustered into Hyphoderma, in which H. crystallinum was sister to H. variolosum, H. membranaceum was retrieved as a sister species of H. sinense, and H. microporoides was closely grouped with H. nemorale. In addition to new species, map to show global distribution of Hyphoderma species treated in the phylogenetic tree and an identification key to Chinese Hyphoderma are provided.

Four new wood-inhabiting fungal species, Lyomyces bambusinus, L. cremeus, L. macrosporus and L. wuliangshanensis, are proposed based on a combination of morphological and molecular evidence. Lyomyces bambusinus is characterized by resupinate basidiomata with colliculose to tuberculate hymenial surface and broadly ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. Lyomyces cremeus is characterised by resupinate basidiomata with smooth, cream hymenial surface and ellipsoid, hyaline, thin-walled to slightly thick-walled basidiospores. Lyomyces macrosporus is characterized by pruinose basidiomata with reticulate hymenial surface, presence of three kinds of cystidia and larger basidiospores (6.7–8.9 × 4.4–5.4 µm). Lyomyces wuliangshanensis is characterized by coriaceous basidiomata and ellipsoid, hyaline, slightly thick-walled, smooth basidiospores. The phylogenetic analyses based on molecular data of the internal transcribed spacer (ITS) region sequences revealed that the four new species belonged to Lyomyces. Lyomyces bambusinus grouped with L. sambuci. Lyomyces cremeus clade was sister to a clade comprised of L. microfasciculatus. Lyomyces macrosporus was sister to L. allantosporus. Lyomyces wuliangshanensis was closely related to L. mascarensis.

A new wood-decaying fungus, Xylobolus austrosinensis, is described and illustrated from southern China based on morphological and molecular evidence. It is characterized by the thick and pulvinate basidiomata, numerous acanthocystidia, acanthoid basidia, and ovoid to subglobose basidiospores (4–4.5 × 2.8–3.5 µm). The new species is similar to X. frustulatus, but differs in having acanthoid basidia, rounder basidiospores and a subtropical-tropical distribution. In the phylogenetic tree inferred from ITS sequence data of Stereaceae, five species of Xylobolus, including the new species, formed a clade with relatively strong supports. Xylobolus spectabilis and X. illudens are excluded from the genus based on our analyses. Xylobolus ahmadii, X. brasiliensis and X. peculiare are not accepted in the genus according to their morphological descriptions and unpublished sequence data. Xylobolus gongylodes that was not included in the phylogenetic analyses is temporarily accepted in the genus. An identification key to all six accepted species of Xylobolus is provided.
