Specimens of Crinipellis and Marasmius (Marasmiaceae) collected from Beijing, North China, were studied by morphological and molecular methods. Phylogenetic analyses were performed separately for the two genera based on ITS sequence data. Two new species, C. deutziae and M. pinicola, were found, and C. rhizomaticola was reported from China for the first time. Crinipellis deutziae is characterized by small basidiocarps, large and variably shaped basidiospores measuring 8.8–11 × 7.5–9.5 µm, the presence of both cheilocystidia and pleurocystidia, and growing on Deutzia parviflora. Marasmius pinicola is characterized by small basidiocarps, cylindrical, reniform to phaseoliform basidiospores measuring 6–8 × 3.5–4.2 µm, often capitate cheilocystidia, and pleurocystidia, and growing on fallen leaves of Pinus tabuliformis. Descriptions and illustrations are provided for the three species. The results of this study contribute to the knowledge of the species diversity of macro-fungi in Beijing. [ABSTRACT FROM AUTHOR]

As an important public space in the city, street space is the second residence of people. Taking Yangmeizhu Street as the research object, this study established a street microclimate model in Beijing through microclimate measurement and simulation, and then calculated thermal comfort index of the street and evaluated thermal comfort of the street space and distribution model. The evaluation method used grid method to decompose and study and made several 10 m × 10 m grids for inner space of the street, so as to compare deeply difference of microclimate environment in the street and analyze quantitatively relevance between street space elements (street pavement, street greening, building shadow coverage) and thermal comfort (physiological equivalent temperature PET) in the data. Finally, adaptive strategy of microclimate on street level was put forward to improve the environmental quality of public space in the old city by means of landscape design, aiming at creating a resilient and humanized street space and improving adaptability of microclimate and thermal comfort for living.
