Preliminary Study On Species Diversity Of Freshwater Fungi In Shandong Province

Saprophytic ascomycetes are important biodiversity components in fungi. The quantity of saprophytic ascomycetes reported from China is far away from that in the world though our country possessing vast territory. To carry out the investigation of diversity on saprophytic ascomycetes of China,the main purposes of the present thesis are to study on species and distribution of saprophytic ascomycetes in parts of China. At the same time, saprophytic ascomycetes were examined, isolated and preserved for the further use of saprophytic ascomycetes resources.About 1200 stems,leaves,tree barkes of plants were collected from Mt.Huang (Shimen gorge, Jiulong waterfall, Ciguang pavilion), Wuyi Mountain (Huxiao precipice, Yixiantian, Qinglong waterfall, Longchuan gorge, Wanglong valley), Changbai Mountain, Yimeng Mountain,Kunyu Mountain(Sanlin field, Jiulong pool), Yichang and Sichuan during 2007 to 2008.The specimens were brought back to the laboratory in the sterile plastic bags and were examined directly while they were still fresh and moist under stereo-microscope or incubated in the moist boxes.3 classes 9 orders 17 familfes 23 genera and 38 species of saprophytic ascomycetes were identified. Among them,2 taxa were regarded as new genera recorded for China,19 taxa were regarded as the new recorded species for China,14 taxa had been reported in China, and 3 taxa were unidentified species. The generic establishment, evolution history, characteristics, distribution locality and latest classification, anamorph and related species were described and discussed detailedly.New recorded genera:Phaeochora,Isthmiella.New recorded species:Didymosphaeria dimastospora, Leptosphaeria brightonensis, Leptosphaeria millefolii, Leptosphaeria suffulta, Massarinula dendroclami, Massarinula gloeospora, Phaeosphaeria humerata, Phaeosphaeria marciensis, Massariosphaeria mosana, Anthostomella calamicola, Anthostomella nitidissima, Anthostomella rhaphidophylli, Anthostomella smilacis, Anthostomella tenacis, Anthostomella tomicoides, Rosellinia sublimbata, Phaeochora steinheilii, Melanopsamma pomiformis, Isthmiella abietis. Genera have been previously reported from China:Didymosphaeria, Leptosphaeria, Lophiostoma, Massarinula, Astrosphaeriella, Schizostoma, Phaeosphaeria, Phragmogibbera, Botryosphaeria, Gloniella, Rhytidhysteron, Massariosphaeria, Nitschkia, Coniochaeta, Amphisphaeria, Diatrypella, Collodiscula, Anthostomella, Hypoxylon, Rosellinia, Melanopsamma.Species have been previously reported from China:Leptosphaeria macrospora, Lophiostoma curtum, Schizostoma vicinum, Phragmogibbera herbicola, Gloniella bambusae, Rhytidhysteron hysterinum, Nitschkia confertula, Coniochaeta sordaria, Amphisphaeria stellata, Diatrypella favacea, Collodiscula japonica,Hypoxylon perforatum, Rosellinia mammiformis, Rosellinia tienpinensis.
