Transdanubia: 123, Southern Transdanubia: 38, Transdanubian Mountains: 746, Northern Mountains: 180, and the Great Plain: 218 (Figure L). 96% of the taxa of fungi producing flies belongs to the Agaricales s.l. group, the remaining part belong to other groups of macrofungi. The number cited in previous publications (410 in Dely-Draskovits 1972) were altered partly due to the above-mentioned exclusion of samples not yielding producing flies, and according to recent changes in mycotaxonomy. The collected species of the Agaricales s.l. group were named according to the nomenclature given by Moser (1983). In the case of the Agaricus group Cappelli's nomenclature (1984), in the case of other macrofungi those of Jülich (1984), and Michael et al. (1986) were used. In the studied material there were several species of Agaricales s.l. ordo, belonging to 16 families. Most often species of Boletaceae, Tricholomataceae, Amanitaceae, Agaricaceae, Cortinariaceae and Russulaceae families were found (table 1, 3.). Table 1.

Here we give the number of rearing samples produced from the different fungi taxa: Boletus (69), Tricholoma (59), Amanita (62), Agaricus (64), Cortinarius (89), Lactarius (82), Russula (312). The number of rearing samples per taxa, from which Diptera emerged: Russula cyanocantha 27, Boletus edulis, + B. aestivalis 31, R. vesca 23, R. delica s.l. 20, R. rosacea 19, R foetens 19,Amanitarubescens 19,/?. heterophylla 19, R.pectinatoides l&,R.densifolias.l. ll.Suillus granulatus 17 and Leccinum griseum 16. From the identified Hungarian Agaricales s.l. taxa (Babos 1989) about 25% is represented in this study. From the most common 160 fungi 125 yielded flies, i.e. we could raise flies from 80% of common species.
