LABOULBENIALES - Agentschap voor Natuur en Bos

5. CONCLUSION AND SUGGESTIONSIn The Netherlands a total of 35 species of Laboulbeniales have beenrecorded up to now, starting with the very first observation in the 1940s. Thehosts represent 5 families, 11 subfamilies, 24 genera and 57 species. Until now,no Dutch insect collections have been screened by mycologists in search forLaboulbeniales, except (partly) the insect collection at the NatuurmuseumBrabant (Tilburg). There is no doubt that a systematic study of insect collectionsof The Netherlands will result in a considerable increase of the number of bothhosts and parasites.Since 1995, the presence of all kind of organisms in De Kaaistoep has beenintensively studied. Our short prospection has resulted in nine species ofLaboulbeniales, six of which are new for The Netherlands: Laboulbenia calathi,Laboulbenia eubradycelli, Hesperomyces virescens, Rhachomyceslasiophorus, Stichomyces conosomatis and Stigmatomyces majewskii. Thelatter is rare; it has been reported just twice, i.e. from France (type, DAINAT etal., 1974) and Austria (ERHARD, 2001).Yet, other species will be discovered in De Kaaistoep, since the observednumber of species in an area depends on the diversity of habitats in that areaand perhaps even more the intensity of searching for new species. In DeKaaistoep, more research should be done in order to find Laboulbeniales:capturing of insects and screening for Laboulbeniales. However, these firstresults confirm the entomological and mycological value of the naturelandscape De Kaaistoep. They also emphasize the persistent need forinventory.P a g e | 98
