Siricid woodwasps live in obligatory nutritional symbiosis with fungi. Screening of symbionts from mycetangia of emerging Xiphydria females (X. longicollis, X. prolongata, X. camelus, X. picta) from 28 locations and four tree genera yielded 1 389 isolates. Each female carried a pure culture of a single fungus. In X. longicollis (Quercus), Daldinia childiae was either the only fungus or a highly dominant one in the samples from moderately dry oak-hornbeam (QuercuseCarpinus betula) forests. Females from the alluvial sites harboured D. childiae and Daldinia decipiens X. camelus and X. picta (Alnus) shared the dominant symbiont D. decipiens whereas X. camelus from Betula carried D. decipiens and D. petriniae In X. prolongata, D. childiae was the dominant species followed by an undescribed Daldinia sp. (0e20 percent of isolates); D. decipiens was rare and in three females Hypoxylon macrocarpum was found
