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.

Xylaria fusispora, an undescribed species of Xylaria (Xylariales, Xylariaceae), is described and illustrated as a new species based on collections from Guizhou Province, China. Both morphology and phylogenetic analysis of nrDNA ITS sequences support the establishment of this new species. The fungus is characterized by its fusoid-equilateral ascospores and an ascus apical ring not bluing in Melzer’s reagent. The differences between the new species and the related fungi are discussed.

A New Species

A new species, Scrophularia jinii (Scrophulariaceae), from Central China is described and illustrated. This new species was formerly misidentified as S. fargesii, from which it differs in many morphological characters. Moreover, it is distinct with all known Scrophularia species in its unique deeply double serrate leaf margin with 3–7 big teeth on each side. Molecular phylogenetic analysis further supports its species delimitation and suggests a close relationship with several Japanese and North American species.

Background – Ongoing studies of Brazilian Rubiaceae revealed an undescribed species of Amaioua endemic to Atlantic Forest (Restinga and Semideciduous forest) of the state of Bahia, which is here described and illustrated, and its morphological characters are discussed and compared with those of similar species. Methods – This study is based on examinations of herbarium specimens, samples preserved in 60% ethanol, field observations, and digital images. Herbarium specimens of the CAY, CEPEC, HBR, IBGE, K, MBM, NY, RB, U, UB, UFG, and US herbaria were directly studied. Additional images of herbarium specimens were studied online. Results – Amaioua longipedicellata Delprete & J.G.Jardim is here described, illustrated and compared with the two most similar species, i.e., A. glomerulata (Lam. ex Poir.) Delprete & C.H.Perss. and A. intermedia Mart. A table comparing the morphological characters of these three species, and an appendix with selected specimens studied of A. glomerulata and A. intermedia are included.

A new species of Osteocephalus (Anura: Hylidae) from Colombia, with comments on the morphological and behavioral diversity within the genus. A striking, undescribed species of Osteocephalus from the Amazonian slopes of the Andes in Departamento de Putumayo in southern Colombia is a member of the Osteocephalus buckleyi Group. Aside from minor morphological characters, the new species differs from all other members of the group by having a golden yellow iris with a median horizontal black stripe. The diversity in morphological and reproductive behavior reveals various features that are phylogenetically signifcant, but several species remain to be described.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

Microprosthema semilaeve, a fairly common spongicolid shrimp of reefal habitats in the Western Atlantic and Caribbean is redescribed and figured based on type material and an additional 78 specimens from the majority of its known zoogeographical range. It is distinguished from the Indo-Pacific species of M. validum and an undescribed species of Microprosthema with which it has been confused in the literature by a number of morphological characters. A new species of Microprosthema from deeper waters off the Dry Tortugas and closely related to M. inornatum Manning & Chace, 1990, is described and illustrated. Microprosthema jareckii Martin, 2002 is synonymized with M. manningi Goy & Felder, 1988. A key to the Western Atlantic species of Microprosthema is presented.

Allium xinlongense from western Sichuan Province, China, is described as a new species. Its diagnostic morphological characters were confirmed to be valid by comparing them to those of related species, such as A. maowenense, A. chrysanthum, A. rude, A. xichuanense, A. chrysocephalum, and A. herderianum. Molecular phylogenetic analysis (combining ITS and rpL32-trnL markers) indicated that this new species is a member of Allium sect. Daghestanica.

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.

Molecular Phylogenetic Data

A new species, Amanita glarea, is described and illustrated from Pakistan. Molecular phylogenetic data derived from internal transcribed spacer (ITS) and nuclear ribosomal large subunit (LSU) regions along with morphological characters make it distinct from other currently known Amanita species. Amanita glarea is characterized by a grayish brown, slightly umbonate, pileus having universal veil remnants and striate margins, a long ringless stipe with a saccate volva bearing yellowish brown patches on the verrucose surface, inamyloid globose to subglobose basidiospores, and a filamentous pileipellis with some inflated round to elongated cells. Phylogenetic analysis of nuclear ribosomal ITS and LSU nucleotide sequences resolve A. glarea with other taxa in Amanita section Vaginatae.
