Molecular Characters

A new poroid wood-inhabiting fungus in the Polyporales, Luteoporia citriniporia sp. nov., is described from Sri Lanka based on morphological and molecular evidence. L. citriniporia is characterized by an annual growth habit; resupinate basidiocarps with lemon yellow pores when fresh becoming buff to clay pink upon drying, a distinct snow white and fimbriate sterile margin, tissues becoming pink in KOH, a monomitic hyphal system, generative hyphae thin- to distinctly thick-walled, usually encrusted with fine yellow crystals, and oblong-ellipsoid to subcylindrical basidiospores measuring 3.4–4.2 × 1.8–2.1 µm. The phylogenetic analysis based on ITS + nLSU rDNA sequences shows that the new species belongs to Luteoporia, forming a monophyletic lineage with strong support (100% BS, 100% BP, 1.00 BPP) and is closely related to L. albomarginata; the lineage groups with Crustodontia chrysocreas, Phlebiporia bubalina and Mycoacia uda. Both morphological and molecular characters confirm the placement of the new species in Luteoporia.

The Family

A new poroid wood-inhabiting fungus in the family Steccherinaceae, Steccherinum fragile sp. nov., is described and illustrated from China based on morphological and molecular evidence. The species was collected in Yunnan Province, growing on the ground and undersides of rotten angiosperm wood. S. fragile is characterized by an annual growth habit, resupinate basidiocarps with salmon to peach pores when fresh becoming cinnamon buff to pinkish buff upon drying, a thin margin with distinct rhizomorphs, a monomitic hyphal system, generative hyphae thin- to distinctly thick-walled with simple septa, neither amyloid nor cyanophilous. The phylogenetic analysis based on ITS + nLSU rDNA sequences shows that the new species belongs to Steccherinum, forming a monophyletic lineage with strong support (100% BS, 100% BP, 1.00 BPP). In addition, a new combination, S. subcollabens, is also proposed based on examination of its type material and phylogenetic analysis. Phylogenetically, Steccherinum fragile is closely related to S. amapaense and groups with S. subcollabens, S. formosanum and S. collabens. Both morphological and molecular characters confirm the placement of the new species and combination in Steccherinum.

Fungal Genus

A new poroid wood-inhabiting fungal genus, Crassisporus gen. nov., is proposed on the basis of morphological characters and molecular evidence. The genus is characterized by an annual growth habit, effused-reflexed to pileate basidiocarps with pale yellowish brown to yellowish brown, concentrically zonate or sulcate, and velutinate pileal surface, a trimitic hyphal system with clamped generative hyphae, tissues turning to dark in KOH, oblong to broadly ellipsoid, hyaline, smooth, and slightly thick-walled basidiospores. Phylogenetic analysis based on ITS+nLSU sequences indicate that Crassisporus belongs to the core polyporoid clade. The combined ITS+nLSU+mtSSU+EF1-α+RPB2 sequences dataset of representative taxa in the Polyporaceae demonstrate that Crassisporus is grouped with Haploporus but forms a monophyletic lineage. In addition, four new species of Crassisporus, C. imbricatus, C. leucoporus, C. macroporus, and C. microsporus are described.

A new poroid wood-inhabiting fungal species, Atraporiella yunnanensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by cream pore surface when dry, which is easy to separate from substrate and very rapidly stained dark brown to black when bruised; hyphal system monomitic with generative hyphae hyaline to pale brown, thin-walled, unbranched, interwoven; slightly allantoid basidiospores, 2.2–3 × 0.8–1.5 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that Atraporiella yunnanensis belonged to the residual polyporoid clade, formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to A. neotropica, and then grouped with other related genera: Antrodiella, Pouzaroporia, Steccherinum and Xanthoporus. Both morphological and molecular characters confirmed the placement of the new species in Atraporiella.

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.

A new poroid wood-inhabiting fungal species, Perenniporia bostonensis sp. nov., is proposed based on morphological and molecular characters. The species is characterized by resupinate, cream to buff pore surface; a dimitic hyphal system with skeletal hyphae strongly dextrinoid, unbranched, interwoven and a distinct wide lumen; ovoid to broad ellipsoid, non-truncate, hyaline, distinct thick-walled, smooth, dextrinoid basidiospores, 3.5–4.5 × 3–4 µm. The internal transcribed spacer (ITS) and the large subunit (LSU) regions of nuclear ribosomal RNA gene sequences of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and bayesian inference methods. The phylogenetic analysis based on molecular data of ITS+nLSU sequences showed that P. bostonensis recognized in Perenniporia sensu stricto. The new species formed a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and was closely related to P. bannaensis and P. koreana. Both morphological and molecular characters confirmed the placement of the new species in Perenniporia.

A new mycoparasitic fungal species, Tuberculina photiniae sp. nov., is proposed based on morphological and molecular evidence. The species is characterized by its depressed hemispherical pale lilac to greyish purple sporodochia breaking through leaf surfaces, septated conidiophores with vinaceous lower parts and colourless upper parts, and the presence of colourless globose, subglobose or scarcely wide-ellipsoid conidia. Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analysis based on molecular data of ITS sequences showed that Tuberculina photiniae belongs to the Tuberculina-Helicobasidium clade and is closely related to H. longisporum and H. mompa. Further investigation was carried out for representative taxa in the Tuberculina-Helicobasidium group based on ITS+nLSU sequences in which the results demonstrated that the new species formed a monophyletic lineage and grouped with H. longisporum and H. mompa. Both morphological and molecular evidence confirmed the placement of the new species in the Tuberculina-Helicobasidium clade.

Trapping Devices

O. laevimarginata is here described as a new species, and also its asexual morph could not be assigned to an existing taxon. Anamorphic strains were obtained from three teleomorph specimens which were collected at different sites and dates. The anamorph is characterized by cylindric-ellipsoid to oblong conidia, mainly 1-septate, growing either singly or mostly from 2–10 denticles in a capitate arrangement on the tip of conidiophores. These morphological characters are similar to those of the nematophagous anamorph genus Arthrobotrys, but the present isolates lack the ability to produce any trapping devices when contacting with nematodes. Phylogenetic analysis inferred from ITS rDNA sequences on different groups within Orbilia showed that the isolates of O. laevimarginata clustered together in a clade separate from Orbilia crenatomarginata (= Hyalinia crystallina). The two species are close to O. scolecospora and an undescribed species, which all have a crenulate to dentate apothecial margin composed of solid glassy processes. The group clustered distant from those species identified within the nematode-trapping anamorph genera Arthrobotrys, Dactylellina and Drechslerella, but also distant from the non-predacious anamorph genus Dactylella. By combining morphological and phylogenetic analysis, we conclude that the three isolates belong to a single undescribed holomorph species. The morphological differences among the three isolated anamorphic strains, and phylogenetic divergence of nematode-trapping fungi and related species are discussed.
