Enriquebeltrania, a genus of trees and shrubs endemic to Mexico, traditionally has been included in Euphorbiaceae (tribe Adelieae, subfamily Acalyphoideae). It was previously thought to be monotypic with a disjunct distribution on the Yucatan Peninsula and along the Pacific coast in Jalisco and Sinaloa. There is some question about whether Enriquebeltrania should be treated as distinct from Adelia. Morphological and molecular characters (trnL-F spacer and rbcL DNA sequences) were utilized in phylogenetic analyses to determine if Enriquebeltrania belongs to the tribe Adelieae, to test whether it should be recognized as a genus separate from Adelia, and to determine the number of species that should be recognized. Results indicate that Enriquebeltrania does not belong to tribe Adelieae, that it should be recognized as a genus separate from Adelia, and that it consists of two species. The second species, Enriquebeltrania disjuncta, is named and described here.

Abstract A new species of Loimopapillosum Hargis, 1955 is described based on specimens collected from the gills of the diamond stingray, Hypanus dipterurus (Jordan & Gilbert, 1880) (Myliobatiformes: Dasyatidae) captured off Puerto Pizarro, Tumbes Region, northern Peru. Loimopapillosum pascuali n. sp. is distinguished mainly from the type and only species, Loimopapillosum dasyatis Hargis, 1955, by its funnel-shaped male copulatory organ, with an asymmetrical base; the superficial root of the anchor with distal knobs; the deep root of the anchor with a constriction at its base; a single testis; and the number of head organs. Available sequences for members of Monocotylidae in the GenBank as well as partial sequences for the gene 28S and 18S ribosomal DNA from L. pascuali n. sp. were included in phylogenetic analyses, suggesting that Loimoinae (represented in this study by L. pascuali n. sp. and Loimosina sp.) is nested within the Monocotylidae Taschenberg, 1879. Therefore, we confirm the rejection of Loimoidae Price, 1936 and its reincorporation as a subfamily of Monocotylidae, as previously suggested. Loimopapillosum pascuali n. sp. represents the first species of this genus in South America.

A New Species

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

A New Species

During the investigation of fungal microbiome associated with boxwood in the Czech Republic, samples from Buxus sempervirens L. (Buxaceae) plants were collected and used for isolation. Two fungal strains were proposed as a new species Pyrenochaetopsis kuksensis based on morphology as well as phylogenetic analyses of ITS, LSU, rpb2, and tub2 sequence data. Detailed descriptions and phylogenetic relationships of the new taxon are provided.

Molecular Characters

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.

It is my greatest pleasure and honour to contribute a part of the series of my studies on the helminth fauna of Japan in honour of Professor R. T. Leiper, one of the most distinguished helminthologists in the world. The material on which the present paper is based was collected at the Tamano Marine Laboratory of Okayama University on the Inland Sea of Japan except for a new species of Raphidascaroides which was taken by Mr. T. Yamamoto at the Marine Biological Laboratory, Kyoto University, on the Pacific coast of Wakayama Prefecture. Acknowledgments are due to the staff of the Tamano Marine Laboratory and also to Mr. Yamamoto for their generous supply of the material.

A New Species

This study presents one telamonioid species new to science based on morphological characteristics and molecular phylogenetic analyses. Cortinarius khinganensis was collected from the Greater Khingan Mountains, Northeast China and it is characterized by hygrophanous, vivid brownish red and striate pileus, white universal veil, and subglobose spores. According to phylogenetic analyses results, C. khinganensis belongs to the section Illumini, which is a lineage distantly related from subgenus Telamonia sensu stricto. Detailed descriptions of the new species and the comparisons with morphologically similar species are provided. The phylogenetic relationships within the section Illumini are also discussed.
