Abstract:

The studies on lichens in Anhui Province has lasted for more than 60 years， and the sites of lichen field study and specimen collection are over 20 areas， with Mt Huangshan being investigated more thoroughly The situation and the study results of Anhui Province on lichen research were summarized in this paper based on examining specimens and consulting literatures， combined with the research results of the author， so as to provide information for other researchers and future studies Totally 203 species or taxa under species among 57 genera had been reported from this area by the end of 2012， with Cladonia as the largest genus Among them， 23 species in 16 genera are crustaceous lichens， 40 species in 7 genera are fruticose lichens， and 140 species in 34 genera are foliose lichens There are 22 genera which has only one species in each genus Among the 203 taxa， there are 98 ones live in only one certain type substratum， with 54 species of corticolous lichens， 22 species of saxicolous lichens， and 8 species living on soil Eleven lichen substance， such as atranorin， zeorin， fumarprotocetraric acid and salazinic acid， were detected by CT， MCT and TLC， and the most common lichen substance is atranorin， with 77 species in 22 genera containing such chemical substance A certain lichen substance may be correlated with some lichen taxa， or deposited in a certain morphological part Two researches about numerical classification and diversity of corticolous lichens and floor lichens from Yaoluoping were carried and the results of Spearman rank correlation showed that 39 corticolous lichen speciespairs were significant positively associated， among which 16 were very significant associated， but no speciespair was negatively Associated Fishers exact test indicated that 10 floor lichen speciespairs were very significant positively associated and four speciespairs were significant positively associated， but no speciespair of the two types of lichens was negatively significant associated Further Fishers exact test demonstrated that the competition between the species was low In general， the lichens in Anhui Province were poorly understood except for their taxonomy Anhui Province lies in the climatic transitional zone of China， so studies on lichens in this area are of great significance in understanding lichen biodiversity
