“…However, in the past two decades, Guiyang has witnessed rapid urbanization, which poses threats to the habitats of various organisms. The process of urbanization not only encroaches upon the living space of other organisms but also negatively impacts their survival through radiation, emissions, waste, and pollutants generated by human activities [10] .…”

Objective To investigate the species diversity of the genus Russula Mushroom in Guiyang City, China, based on morphological characteristics and taxonomic research, in order to lay a foundation for future development and utilization of the medicinal-food value of the Russula Mushroom genus. Methods Russula Mushroom specimens were collected in Guiyang City and its surrounding areas. Morphological and molecular identifications were conducted, comparing the collected specimens with existing specimens in the herbarium. Macroscopic and microscopic characteristics of the species were described. DNA sequences from the specimens were compiled, and a phylogenetic tree was constructed to confirm species classification. Results A total of 30 Russula Mushroom specimens were collected in Guiyang City, including 21 known species. Among them, 12 species were identified based on morphological characteristics, while 8 species were identified through molecular Analysis. Among the identified species, 10 were edible mushrooms, and 4 were medicinal mushrooms. Literature records indicate that Guiyang City is home to 33 species of the Russula Mushroom genus. Conclusion The Russula Mushroom resources in Guiyang City include 16 edible species and 8 medicinal species. Among them, Russula crustosa, Russula cyanoxantha, and Russula delica have anti-tumor effects. Russula densifolia and Russula foetens are effective in treating limb spasms and musculoskeletal discomfort. Russula nigricans has properties for dispelling wind, cold, and dampness, as well as soothing tendons and activating collaterals. Russula rosea is rich in anti-cancer substances. Russula virescens can clear the liver, improve eyesight, and regulate Qi flow. These species all have the potential for medicinal development.

Background The relationship between climate and radial growth of trees exhibits spatial variation due to environmental changes. Therefore, elucidation of how the growth–climate responses of trees vary in space is essential for understanding forest growth dynamics to facilitate scientific management with the ongoing global climate warming. To explore the altitudinal and slope variations of these interactions, tree-ring width chronologies of Larix olgensis A. Henry were analyzed in the southern Lesser Khingan Mountains, Northeast China. Results The radial growth of L. olgensis exhibited significant 5- to 10-year periodic changes at three altitudes and two slopes, and the frequency change occurred mainly during the early growth stage and after 2000. The radial growth of L. olgensis was significantly negatively correlated with September precipitation only at low altitudes, but also with the mean temperature in July–August and the mean maximum temperature in June–August at high altitudes. The radial growth of L. olgensis at low and middle altitudes as well as on the sunny slope led to a higher demand for moisture, while temperature was the key limiting factor at high altitudes and on the shady slope. Conclusions The climate–radial growth relationship of L. olgensis exhibits altitudinal and slope variability. This study quantitatively describes the spatially varying growth–climate responses of L. olgensis in the southern Lesser Khingan Mountains, which provides basic data for the management of L. olgensis forests and the prediction of future climate impacts on forest ecosystems.
