Saprobic fungi on bamboo culms

This paper examines the taxonomic composition of saprobic fungi on dead cul ms of Bambusa spp. and Dendrocalamus spp. in the Philippines and in Hong Ko ng. A total of 2044 collections of saprobic fungi were made, comprising 24 ascomycetes, 56 mitosporic taxa, and I basidiomycete. The most commonly enc ountered ascomycete families on both hosts and at both sites were the Xylar iaceae and Valsaceae, which were represented by 20% and 21.7% of the total collections, respectively. Other common families were the Amphisphaeriaceae (8.9%) and Chaetomiaceae (11.9%). The most common hyphomycetes on both hos ts at both sites were Acrodictys bambusicola (9.6%), Curvularia lunata (9%) , Cladosporium cladosporioides (8.3%), Corynespora foveolata (7.9%), Ellise mbia vaginata (6.1%), Phaeoisaria philippinensis (6.5%), and Acremonium kil iense (6%). With the exception of Diploythiella bambusina which was observe d on Bambusa at both sites, the genera of coelomycetes differed at both sit es. Species of Bambusa from both sites yielded more collections of saprobic fungi (1537), than did Dendrocalamus (507). Differences in the mycota betw een the two sites were observed. Collections of saprobes on both hosts in t he Philippines were higher (1278) than in Hong Kong (766).
