A new, white-rot, poroid, wood-inhabiting fungal genus, Rhomboidia, typified by R. wuliangshanensis, is proposed based on morphological and molecular evidence. Collected from subtropical Yunnan Province in southwest China, Rhomboidia is characterized by annual, stipitate basidiomes with rhomboid pileus, a monomitic hyphal system with thick-walled generative hyphae bearing clamp connections, and broadly ellipsoid basidiospores with thin, hyaline, smooth walls. Phylogenetic analyses of ITS and LSU nuclear RNA gene regions showed that Rhomboidia is in Steccherinaceae and formed as distinct, monophyletic lineage within a subclade that includes Nigroporus, Trullella, and Flabellophora .

A new polypore, Antrodia yunnanensis, collected from southwestern China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by annual, resupinate basidiocarps with greyish blue to dark greyish blue pore surface upon drying, round to angular pores measuring 2–3 per mm, a dimitic hyphal system with clamped generative hyphae, subicular hyphae bearing fine crystals, and cylindrical, thin-walled, smooth basidiospores measuring 7–9.9 × 2.5–3.1 µm. Molecular phylogeny inferred from ITS and nLSU sequence data showed that samples of A. yunnanensis formed a distinctive lineage in Antrodia sensu lato, and it nested a sister group with A. tropica.

Molecular Characters

A new white-rot species, Phlebiopsis lacerata sp. nov., is proposed based on morphological and molecular characters. It is characterized by resupinate to effuse-reflexed basidiomata, a monomitic hyphal system with simple septate generative hyphae, conical cystidia that are thick-walled, heavily encrusted with large crystal in the apical part, and ellipsoid basidiospores (4–5.5 × 3–3.5 µm). Phylogenetic analyses of the ITS and LSU nrRNA gene regions showed that P. lacerata belongs to the Phanerochaetaceae and is nested in the phlebioid clade. Further investigation based on ITS+nLSU sequences with more representative taxa in Phlebiopsis demonstrated that P. lacerata forms a monophyletic lineage with a strong support (100% BS, 100% BP, 1.00 BPP) and then groups with P. crassa.

A new white-rot fungus, Phlebia wuliangshanensis, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by an annual growth habit, resupinate basidiocarps with a smooth to tuberculate hymenial surface, a monomitic hyphal system with thin- to thick-walled generative hyphae bearing simple septa, presence of cystidia, and narrow ellipsoid to ellipsoid basidiospores (5–6 × 3–3.7 μm). Our phylogenetic analyses of ITS and LSU nrRNA sequences performed with maximum likelihood, maximum parsimony, and Bayesian inference methods support P. wuliangshanensis within a phlebioid clade in Meruliaceae (Polyporales). ITS+nLSU sequence analyses of additional Phlebia taxa strongly support P. wuliangshanensis within a monophyletic lineage grouped with P. chrysocreas and P. uda .

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.

Crenea Aubl. (Lythraceae) is a ditypic genus of subshrubs occurring in mangrove vegetation on the coasts of northern South America. Phylogenetic analyses based on morphology have offered unresolved and conflicting phylogenetic positions for the genus in the family. This study presents the first molecular sequences for Crenea, from nrITS, rbcL, trnL, trnL-F, and matK regions. Molecular phylogenetic analyses find full support for Crenea within Ammannia L., a relationship not previously recognized. Ammannia is a globally distributed genus of terrestrial to amphibious herbs mostly occurring in freshwater marshes and wetlands. It was recently reconfigured based on phylogenetic evidence to include the genera Nesaea Comm. ex Kunth and Hionanthera A. Fern. & Diniz. The transfer of Crenea to Ammannia further extends the morphological, ecological, and biogeographical diversity of Ammannia and provides the final evidence defining Ammannia as a monophyletic lineage of the Lythraceae. A revised circumscription of Ammannia s.l. adds several new morphological character states and the first species in the genus restricted to mangrove vegetation. Two changes in taxonomic status are made: Ammannia maritima (Aubl.) S. A. Graham, P. W. Inglis, & T. B. Cavalc., comb. nov., and Ammannia patentinervius (Koehne) S. A. Graham, P. W. Inglis, & T. B. Cavalc., comb. nov. The new combinations are described, a list of exsiccatae examined is provided, and the effects of the reconfiguration to the morphology and biogeography of the genus are detailed.

Inference Methods

A new wood-inhabiting fungus, Phlebia nigrodontea, is proposed based on a combination of morphological features and molecular evidence. The species is characterized by a grandinioid hymenophore with vinaceous brown to black colour, a monomitic hyphal system with clamped generative hyphae and ellipsoid, colourless, thin-walled, smooth basidiospores (3.9–4.9 × 2.3–3.1 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses carried out using maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on the molecular data of ITS+nLSU sequences showed that P. nigrodontea nested within the phlebioid clade. A further investigation of more representative taxa from Phlebia, based on ITS+nLSU sequences, demonstrated that the species P. nigrodontea formed a monophyletic lineage with strong support (100% BS, 100% BT, 1.00 BPP) and closely grouped with P. chrysocreas.

A New Species

A new orchid species, Cymbidium yunnanensis (Orchidaceae; Epidendroideae; Cymbidieae), from Yunnan Province, China, is described and illustrated. Based on morphological and molecular analyses, we demonstrate that this new species is similar to C. floribundum, but it differs in its smaller size, leaves 5–15 cm, shorter scape, white flowers with pale purplish markings on its sepals and petals, lip with purplish red blotch, petals narrowly falcate oblong and lip midlobe nearly round with column foot 1.5–2.0 mm long. Phylogenetic analyses based on nuclear ribosomal ITS and plastid (matK, rbcL) DNA sequence data support C. yunnanensis as a new species.

A bioluminescent macrofungus found growing on dead wood in the mountains of Southwest China, Yunnan Province, Yulong Naxi Autonomous County, is analyzed and described. Phylogenetic analyses of the nuclear ribosomal large subunit (LSU) and internal transcribed spacer (ITS) gene regions place the fungus within the genus Roridomyces and confirm it to be a previously undescribed taxon. Morphological features support phylogenetic conclusions and include a glutinous stipe, a light yellowish-brown to beige or white pileus, and luminescent mycelium. Comprehensive descriptions, macro- and microscopic photographs, and phylogenetic trees are provided, as well as a table containing morphology and distribution of all Roridomyces taxa to aid in species identification and comparison. This is the first member of the genus Roridomyces to be identified in China.
