Campanophyllummicrosporum (Agaricales, Agaricomycetes), Caloceramultiramosa, and Dacrymycesnaematelioides (Dacrymycetales, Dacrymycetes), three new species from Yunnan Province, southwestern China.

Three new species belonging to Basidiomycota from southwestern China are described based on morphological and molecular data. Campanophyllummicrosporum is morphologically characterized by dorsally pseudostipitate, pale orange to brownish orange pileus, excentric to lateral pseudostipe, crowded lamellae, cylindrical-ellipsoid basidiospores 3.0-4.2 × 1.7-2.2 µm, narrowly clavate to clavate basidia 14.5-23.0 × 3.0-4.2 µm, and cylindrical to clavate cheilocystidia 22.0-55.0 × 5.0-10.8 µm. Caloceramultiramosa is morphologically characterized by stipitate, yellowish to orange, dendroid, and dichotomously branched basidiomata, cylindrical to clavate basidia 36.5-52.5 × 3.8-6.1 µm, navicular or reniform, 1-5-septate mature basidiospores 10.4-16.7 × 5.2-7.4 µm. Dacrymycesnaematelioides is morphologically characterized by stipitate and cerebriform, orange to light brown basidiomata, cylindrical to clavate, smooth or roughened basidia 38.5-79.5 × 6.5-10.6 µm, broadly and elliptic-fusiform, 7-septate mature basidiospores 18.5-28.6 × 8.9-13.8 µm. These three new species are supported by the phylogenetic analyses using maximum likelihood (ML) and Bayesian inference (BI) analyses with combined nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) and large ribosomal subunit (LSU) sequences. Full descriptions and photographs of these new species are provided.

Three-dimensional transient numerical simulation for intake process in the engine intake port-valve-cylinder system.

This paper presents a KIVA-3 code based numerical model for three-dimensional transient intake flow in the intake port-valve-cylinder system of internal combustion engine using body-fitted technique, which can be used in numerical study on internal combustion engine with vertical and inclined valves, and has higher calculation precision. A numerical simulation (on the intake process of a two-valve engine with a semi-sphere combustion chamber and a radial intake port) is provided for analysis of the velocity field and pressure field of different plane at different crank angles. The results revealed the formation of the tumble motion, the evolution of flow field parameters and the variation of tumble ratios as important information for the design of engine intake system.
