During recent investigations on Endamoeba blattae (Bütschli) Leidy of the common cockroach, Blatta orientalis, there were observed in the hindgut of the host, two other distinct amoebic species. Both appear to be truly entozoic, but contrast strikingly with E. blattae both in morphological features and life cycle. They are interesting not only in being among the comparatively few species yet reported from insects, but also in their relationships to certain of the amoebae of vertebrates.

The genus chiton Loricella is revised. It comprises nine species. Two of these species, L. neoguinensis n. sp. and L. solomonensis n. sp., are described as new. Based on the analysis of morphological features studied using a scanning electron microscope, a revised diagnosis of the genus is provided. The characters diagnostic for this that distinguish it from the related genus Squamophora are as follows: a tubular hollow inside the dorsal scales, bristles on the dorsal side of the girdle, a wide ventral mouth region, a narrow mantle fold covered with simple longitudinally ribbed scales, smooth ventral scales, pits arranged in longitudinal rows in the central area of the tegmentum, and a bicuspid head of the major lateral teeth of the radula.

During a survey on diversity of freshwater fungi along a north-south latitudinal gradient in Asia, three fresh specimens of Minimelanolocus were collected from submerged wood in streams in northwestern Yunnan Province, China. Based on their distinct morphological features and phylogenetic analyses of combined ITS, LSU and SSU sequence data, Minimelanolocus nujiangensis and M. clavatus are described as new species and M. submersus was recollected from Yunnan, China. Illustrations and descriptions with notes of the three species are provided. This study increases the known diversity of Minimelanolocus and enriches freshwater fungal resources.

During an investigation of fungicolous fungi associated with mushrooms in China, four boleticolous fungi were collected from Sichuan Province. Based on the morphological features and multi-gene phylogenetic analyses this study introduces two new species, Hypomyces ampullaris, and H. sichuanensis. The new species are described and illustrated comprehensively and compared with their related fungi. Hypomyces ampullaris is similar to Sepedonium ampullosporum in forming candelabrum-like conidiophores and producing ampulliform conidia but differs from the latter in having shorter phialides and smaller ampulloconidia. Hypomyces sichuanensis is similar to H. chrysospermus, H. microspermus, and Sepedonium laevigatum in forming poorly developed verticills conidiophores and the shape and size of aleurioconidia. However, the asexual spores of H. sichuanensis averaged somewhat smaller than those of H. chrysospermus and S. laevigatum, and larger than that of H. microspermus. Additionally, H. ampullaris and H. sichuanensis distinct from their close relatives in no pigment discoloration of the PDA medium. These species introduced here, improve our understanding of the diversity of Hypomyces, especially of the boleticolous Hypomyces in China.

Two new species of Trichomycterus from isolated small river basins of southeastern Brazil are described: T. pantherinus, new species, from the Rio Santa Maria da Vit ria basin, and T. caudofasciatus, new species, from the Rio Itabapoana basin. Both new species are diagnosed by a combination of morphological features, also occurring in T. alternatus and T. longibarbatus, including number of pectoral-fin rays, odontodes and branchiostegal rays, long filamentous first pectoral-fin ray and wide opercular patch of odontodes. Trichomycterus pantherinus differs from other congeners by possessing a light orangish yellow flank with dark brown to black rounded spots. Trichomycterus caudofasciatus is distinguished from other species of the genus by having four gray bars on the caudal fin.

Two apomictic, polyploid (x=9) species in Hieracium sect. Alpina are described from the Western Bieszczady Mountains, Eastern Carpathians, Poland, and illustrated with photos of the holotypes. These are H. jasiewiczii (4x) which combines the morphological features of H. alpinum and H. bifidum, and H. wojcickii (4x) of presumably hybrid origin between H. alpinum and H. pseudobifidum. Both new species are probably relicts originated from diploid, sexual H. alpinum with a wider primary range covering also the Western Bieszczady Mountains, which presently occurs only in the Romanian and Ukrainian Carpathians.

Species of Clavaria (Clavariaceae, Agaricales) collected from China were studied using morphological and molecular methods. Two species, C. griseolilacina and C. sinensis were described as new species; both possess branched and pale purple-tinged fruit bodies. However, the former possess a few branched, while the latter is profusely branched. The phylogenetic analysis based on the internal transcribed spacer (ITS) sequences confirmed the distinctions between these two new species and their close relationships with C. rubicundula and C. fumosa in the genus. An evolutionary tendency in genus Clavaria was discussed. Additionally, morphological features of the two new species were described in detail and were illustrated with line drawings and photographs. Holotypes of the new species are deposited in the Mycological Herbarium of Hunan Normal University (MHHNU). The ITS sequences generated in this study were deposited in GenBank. A key is provided for the known Clavaria species in China.

The validity of Genolopa Linton, 1910 has been controversial because the observation of presently recognized critical diagnostic morphological features (spines in the genital atrium and a bipartite, anteriorly spined terminal organ) were omitted from the original diagnosis, and these features were not universally appreciated as important diagnostic features until 2008. Modern taxonomists have been further challenged by inappropriate fixation techniques that have resulted in various interpretations of morphological features. Consequently, named species in the genus have fluctuated among other monorchiid genera depending on various interpretations by taxonomists, and a modern consensus on classifying these species is lacking. This study combines a molecular approach with modern conventional morphological techniques to investigate the validity of Genolopa as a lineage within the Monorchiidae. New morphology and molecular sequence data from the type-species of Genolopa were studied, and two new species in the genus were described, Genolopa vesca n. sp. and Genolopa minuscula n. sp. Interrelationships among the Monorchiidae were explored using Bayesian inference analysis of the partial 28S rDNA fragment, incorporating three species of Genolopa for the first time. The phylogenetic analysis revealed that the genus represents a natural lineage, supporting the presence of spines in the genital atrium in conjunction with a bipartite and anteriorly spined terminal organ as key features of the generic diagnosis. This study also provides for the first time partial 28S rDNA data for Postmonorchis orthopristis, Lasiotocus trachinoti, Lasiotocus glebulentus, and an unidentified species of Lasiotocus.

The fauna of the Asian mirine plant bug genus Cheilocapsus Kirkaldy, 1902 (Mirinae: Mirini) in the Japanese Ryukyu islands and Taiwan is updated, based mainly on new morphological features. Four species are now recognized, with descriptions of two new species, Cheilocapsus maius sp. n. (from Taiwan) and C. martius sp. n. (Ishigaki and Iriomote Islands of the Ryukyus). An annotated checklist including all known congeners and a key to the four species are provided. The phylogenetic relationship between Cheilocapsus and Pantilius Curtis is argued on the basis of their detailed structures and zoogeographical distribution pattern.

Two new species of Russula are described and illustrated in this paper. Russula clavulus is recognised by a pale yellow pileus centre, white margin with tuberculate striation, white to pale lamellae with small pale yellow spots, white to light yellow spore print, subglobose to broadly ellipsoid spores with short or long ridges and hymenial cystidia on lamellae sides that are mainly subclavate or fusiform. Russula multilamellula is morphologically characterised by the brownish orange to hazel pileus centre and satin white to yellowish-white margin with brownish tinge, lamellulae that are usually irregular in length and often anastomosing with lamellae, subglobose to broadly ellipsoid spores with short or long ridges and clavate hymenial cystidia. The combination of morphological features and multigene phylogenetic analyses of ITS-nrLSU-RPB2-mtSSU data indicated that these two new taxa belong to Russula subg. Heterophyllidia sect. Ingratae.
