Taxonomic and phylogenetic studies of Haploporus were carried out. Three species in Haploporus, H. cylindrosporus, H. septatus and H. subpapyraceus, are described as new based on morphological differences and molecular phylogenetic analyses inferred from the internal transcribed spacer (ITS), the large subunit nuclear ribosomal RNA gene (nLSU), the small subunit mitochondrial rRNA gene (mtSSU), the second subunit of RNA polymerase II (rpb2) and the translation elongation factor 1-α gene (TEF1) sequences. Haploporus cylindrosporus is characterized by big irregular crystals occasionally present in the subiculum, an abundant oily substance among hyphae and typically cylindrical basidiospores 10–11.5?×?4.5–5 μm; H. septatus differs from other species in the genus by its leathery to corky basidiomata when dry, small round pores (5–6 per mm), simple septate skeletal hyphae at the edge of the dissepiments, and oblong to ellipsoid basidiospores 8.5–11?×?5–6 μm; H. subpapyraceus is separated by white to cream basidiomata, numerous apically simple septate cystidioles and ellipsoid basidiospores 9–12?×?5.5–8 μm. An identification key to accepted species of Haploporus is provided.  相似文献

Phylloporia is a monophyletic genus within the Hymenochaetaceae as recovered by nuclear large subunit ribosomal DNA (nLSU) sequences. According to the summarization of 38 species accepted in this genus, Phylloporia is characterized by an absence of setae and the presence of abundant thick-walled, colored and tiny basidiospores, although its other morphological characters are highly diverse. Nine herbarium specimens from China, fitting the morphological concept of Phylloporia, were morphologically and phylogenetically studied in detail. The phylogeny inferred from nLSU sequences shows that the nine specimens formed three terminal lineages within the Phylloporia clade. Two lineages being composed of four specimens from Hainan and three from Guizhou were newly described as Phylloporia minutipora and P. radiata, respectively. In Phylloporia, P. minutipora is distinct by a combination of annual, sessile and imbricate basidiocarps, distinctly concentrically sulcate pileal surface with obtuse margin, angular pores of 12–15 per mm, duplex context separated by a black zone, a dimitic hyphal system, and broadly ellipsoid basidiospores of 2.5–3?×?2–2.5 μm, while P. radiata is distinct by a combination of annual, sessile and imbricate basidiocarps, faintly sulcate and radially striate pileal surface, sharp pileal margin, angular pores of 8–10 per mm, duplex context separated by a black zone, a monomitic hyphal system, and broadly ellipsoid basidiospores of 2.5–3.5?×?2–2.5 μm. The third lineage, comprising two specimens from Hainan, was morphologically determined as Phylloporia pulla. This species was recently combined to Phylloporia based on only morphological characters, and the current study for the first time generated its molecular sequences for phylogenetic reference. A key to all 40 species of Phylloporia is provided.  相似文献

Dichomitus hubeiensis Hai J. Li & B. K. Cui sp. nov. is described from the Hubei province, central China. It is distinct in the genus by its cream to straw‐yellow pore surface and large pores (1–2 per mm), both inamyloid and indextrinoid skeletal hyphae, presence of cystidioles and dendrohyphidia in the hymenium, more or less ellipsoid basidiospores (10–14 × 5.6–7.0 µm). Dichomitus kirkii originally described from Zimbabwe was found in the Yunan province, it is new to the Chinese fungal flora, and is characterized by its buff‐yellow to cinnamon‐buff pore surface, entire to lacerate pores (1–2 per mm) and large cylindrical basidiospores (20.8–25.0 × 6.8–8.0 µm).  相似文献

Trichaptum imbricatum, T. perenne and T. podocarpi are three new species from China. They are described, illustrated and compared in this paper with similar species. Trichaptum imbricatum is unique in its imbricate basidiocarps, white to cream hymenophores, small and regular pores, and scattered and thin-walled cystidia. Trichaptum perenne differs from other species in the genus in its perennial and pileate habit, its large pores and entire dissepiments, and oblong, ellipsoid basidiospores. Trichaptum podocarpi is distinguished in having totally resupinate basidiocarps, distinctly long cystidia, and in its habitat on Podocarpus. A key to species of Trichaptum occurring in China is provided; statistical variations of spore dimensions for each species are included in the key.  相似文献

Two new species of Fulvifomes are described from specimens collected in rainforests of Nonggang Nature Reserve of southern China, based on morphological characteristics and molecular phylogenetic analysis of the internal transcribed spacer (ITS) and nuclear large subunit ribosomal DNA (nLSU) sequences. Fulvifomes nonggangensis sp. nov. is characterized by perennial, sessile and solitary basidiocarps, applanate pileus, small cystidioles of 9.9–15.4 × 2.9–3.5 μm, large pores of 5–6 per mm, a dimitic hyphal system, and broadly ellipsoid basidiospores of 4.3–5.3 × 3.3–4.2 μm. F. tubogeneratus sp. nov. is characterized by perennial, sessile, and imbricate basidiocarps, a duplex context, small pores of 7–8 per mm, a dimitic hyphal system, and ovoid to subglobose basidiospores of 5.72 × 5.00 μm.  相似文献

A taxonomic study of poroid Asian species in the Auriculariales was conducted using phylogenetic and morphological methods. Phylogenetic analyses based on the LSU and ITS regions reveal that Elmerina was a polyphyletic genus. Moreover, E. hexagonoides collected from Malaysia and “E. hexagonoides” from Japan formed two distinct clades within a well-supported larger clade with Protomerulius caryae. These taxa comprise a different lineage from the type species of both Protomerulius and Protodaedalea, and we conclude that they are members of the genus Aporpium. The phylogenetic position of E. cladophora (type species of Elmerina) is still unclear, and we retain Aporpium and Protodaedalea as genera distinct from Elmerina. Aporpium strigosum sp. nov. is described to represent Japanese specimens misidentified as E. hexagonoides. Aporpium is characterized by resupinate to sessile basidiocarps, tough-fleshy to leathery context, poroid hymenophore, dimitic hyphal systems with unbranched skeletal hyphae, clavate to pyriform probasidia, and ellipsoid to cylindrical or allantoid basidiospores. Aporpium strigosum is similar to A. hexagonoides, but can be differentiated by the ochraceous to straw-colored basidiocarps, strigose pileus surface with long and stiff hairs, and the larger pores, basidia, and basidiospores.  相似文献

Two new species of Coltricia, C. austrosinensis and C. minima, are described from southern China on the basis of morphological characters and molecular evidence. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions indicated that the two new species were nested within the Coltricia clade in Hymenochaetales. Coltricia austrosinensis is characterized by centrally stipitate basidiocarps, lobed pileal margin, distinctly swollen stipe tip, cinnamon pore surface, large pores (1–3 per mm), and broadly ellipsoid basidiospores measuring 8–10?×?5.5–6.5 μm, with a distribution to date in subtropical China. Coltricia minima is characterized by tiny, centrally stipitate basidiocarps, entire pileal margin, uniform stipe, pileus bearing distinct concentric zones and pore surface dark greyish blue when fresh, small pores (3–4 per mm), narrow tramal hyphae (3.5–4 μm), and broadly ellipsoid to subglobose basidiospores measuring 6–7?×?4–5 μm, and occur in mixed tropical forests.  相似文献

The type species of Polyporaceae (Aphyllophorales) and of other related genera, i.e. Irpex, Grammothele and Theleporus , described by J. Rick were studied. Of the 93 names of species or varieties 34 are invalidly published and 21 are synonyms. Nineteen type specimens were not found and 4 were sterile. Four species were respectively assigned to Datronia, Steccherinum, Trechispora and a cyphellaceous fungus, and were left without specific determination. The following new combinations are proposed: Aporpium substuppeus, Ceriporiopsis latemarginata, Inonotus micantissimus, Junghuhnia polycystidifera, Perenniporia piperis, Phanerochaete furfuraceo-velutinus, Skeletocutis roseolus and Tyromyces atro-albus. Two new species are described: Ceriporiopsis lowei and Gloeodontia americana.  相似文献

A common resupinate thelephoroid fungus was collected in northern Guinean seasonal forests in central and north of Benin (West Africa). The species is reminiscent of Tomentella umbrinospora with respect to the color and thickness of basidiomata and rhizomorphs, the shape of basidiospores in frontal view and the size of subicular hyphae. Both species fall phylogenetically within two clades. Based on detailed anatomical comparison (mostly of rhizomorphs and basidiospores) with the holotype of T. umbrinospora and phylogenetic analyses including ITS rDNA sequences of 40 Tomentella species, T. africana is described as a new species. Genetic distance between the newly described species and T. umbrinospora is 12.1-12.9%, based on ITS rDNA sequences. T. africana is characterized anatomically by yellow-brown thick (0.3-0.8 mm) monomitic rhizomorphs that are commonly covered by irregularly shaped thin hyphae, thin- to thick-walled subicular hyphae of two size ranges, clavate and clamped basidia of 30-60 microm and light yellow to pale brown echinulate basidiospores with irregular shape in frontal view. Detailed anatomical and molecular dissimilarities between T. africana and close species are discussed. Differences between irregularly shaped surface thin hyphae and skeletal ones are highlighted. We stress the relevance of rhizomorphal structures in the discrimination of resupinate thelephoroid fungi.  相似文献

Rhodotus has been regarded as a monotypic genus, consisting of only one species, R. palmatus, for a long time. Morphological and phylogenetic studies were carried out on collections of Rhodotus from temperate, subtropical and tropical China. Our phylogenetic analysis of DNA sequences of three loci (the internal transcribed spacer, the large subunit nuclear ribosomal RNA, and the translation elongation factor-1 alpha) revealed that there are two phylogenetic species in the northern hemisphere, which is in concordance with morphological traits, supporting the division of Rhodotus into two distinct species. Rhodotus asperior is described as a new species that differs phenotypically from R. palmatus in its broadly ellipsoid to subglobose, more roughened basidiospores, longer cheilocystidia with slightly thickened wall, and its occurrence in tropical and subtropical environments. The discovery of this new taxon indicates Rhodotus has a wider distribution than previously thought.  相似文献

Three new species of Inonotus are described and illustrated. Inonotus acutus sp. nov. is characterized by having small, thin basidiocarps with a strongly contracted base, a sharp and undulate pileus margin, ventricose hymenial setae, and ellipsoid, yellowish to yellow-brown, slightly thick-walled basidiospores. Inonotus chrysomarginatus sp. nov. differs in having an annual to perennial growth habit, pileate basidiocarps with a distinctly yellowish buff to golden-yellow margin, distinct setal hyphae and hooked hymenial setae, and broadly ellipsoid to subglobose, pale yellowish, slightly thick-walled and weakly cyanophilous basidiospores. Inonotus rigidus sp. nov. is distinguished by its resupinate and hard rigid basidiocarps, the honey-yellow pore surface, and smaller pores; microscopically, it has ellipsoid, yellowish brown and thick-walled basidiospores, and lacks both setal hyphae and hymenial setae. An identification key to the Chinese species of Inonotus sensu stricto is provided.  相似文献

Two species of the genus Ponticulomyces collected from Japan for the first time are described and illustrated. Ponticulomyces kedrovayae is characterized by its lamellae staining yellow when bruised and in age, stipe lacking an annulus and a pseudorhiza, scattered pileal hairs, and large amygdaliform basidiospores. It mainly occurs on dead wood of Fagus crenata. Ponticulomyces orientalis is characterized by its scattered pileal hairs and broadly ellipsoid to ellipsoid basidiospores. It was collected mostly on dead wood of Cameria japonica.  相似文献

Lignosus hainanensis sp. nov., is described and illustrated on the basis of collections originating from tropical forest in Hainan Province, southern China. Both the morphology and phylogeny support this new species. It is characterized by its centrally stipitate basidiocarps arising from a distinct sclerotium, yellowish brown to cinnamon-brown pileal surface, cream to cream-buff pore surface, trimitic hyphal system with clamped generative hyphae, and oblong ellipsoid to cylindrical basidiospores. Lignosus hainanensis may be confused with L. rhinocerus, also occurring in southern China, but L. rhinocerus can be distinguished by its smaller pores (6–8 per mm) and smaller and distinctly broadly ellipsoid basidiospores (4–5 × 2.8–3 μm).  相似文献
