Species diversity of macrofungi in Gupo Mountain and adjacent areas of Guangxi, China
Abstract
Gupo Mountain is adjacent to the Nanling Biodiversity Conservation Priority Area of China, which nurtures rich biological resources. To understand the diversity of macrofungal species in this area, a survey and collection of macrofungal resources in Guangxi Gupo Mountain Provincial Nature Reserve (abbreviate as Gupo Mountain) and adjacent areas was conducted by random tracking method, and combined morphological and molecular biological methods to identify. The results were as follows: (1) A total of 348 species macrofungal were found in this area, belonging to 175 genera in 69 families in 2 phyla, 6 orders and 17 classes, including 40 species of edible mushrooms, 42 species of medicinal mushrooms and 7 species of toxic mushrooms. (2) The analysis of the species composition of the region showed that the dominant families were nine families, including Agaricaceae, Boletaceae, Entolomataceae and Hymenochaetaceae, etc.; the dominant genera were eleven genera, including Amanita, Crepidotus, Crinipellis, Entoloma, etc. (3) There were two endemic genera in China, namely Fragiliporia and Zangia, and 11 endemic species, namely Coltricia crassa, C. weii, Entoloma caespitosum, E. praegracile, E. subtenuicystidiatum, Fomitiporia tenuitubus, F. torreyae, Fragiliporia fragilis, Perenniporia nanlingensis, P. subtephropora and Tremella cerebriformis. (4) Analysis of the funga composition of macrofungi in Gupo Mountain and adjacent areas revealed that the composition of families could be divided into cosmopolitan element (66.67%), pantropic element (17.39%) and north temperate element (15.94%); while the genera could be divided into seven elements, among which the cosmopolitan element is the most dominant (61.71%), and pantropic element (20.57%) and north temperate element (13.71%) rank second and thirdly. The rich species data provide basic information for the assessment of macrofungal species diversity and sustainable utilization of resources in Gupo Mountain and adjacent areas.
