erdőben, a Soproni-hegységben vegyeserdőben fordult elő kötött talaj on. ) BABOS, M.: Rare and interesting fungus species of the Hungarian sandy areas. I. Mycologists became acquainted with the Gasteromycetes of the Great Hungarian Plain through the investigations of HOLLÓS (1903). In the last decade the investigation of the fungus vegetation of the area has been continued. BOHUS (1969, 1970a, b, 1971, 1972) and BABOS (1968) published new taxa (

Agaricus bre- sadolianus

, A. pseudopratensis

, Armillaria rickenii

, Cortina rius moserianus

, Hebeloma ochroalbidum

, Inocybe aeruginascens

, Lepista luscina var, parva

) and several other European rare species were observed and published (BOHUS 1962, 1969, 1970a, b; BABOS 1969, 1970). This paper gives a description of further rare and interesting species. The herbarial specimens are to be found in the collection of the Botanical Department of the Hungarian Natural History Museum. Calocybe obscurissima (PEARS.) MOS. - (Pig. 1.). Cap and stem violet-greybrown, lamellae white-creamy. It resembles a small Melanoleuca apecies with dark cap. We succeeded in collecting it in large numbers in sandy Robinia forests. It is described by KÜHNER - ROMAGNESI (1953), JOSSERAND (1959) and HORA (i960) as a species of coniferous forests. Hungarian Robinia forests, however, frequently harbour species which occur first of all in coniferous woods. These species without mycorrhiza probably favour the litter cover of both the Robinia and coniferous forests. Inocybe agardhii (LUND.) ORTON (Pigs. 7-8.). Similar to I. dul camara

, but stem with a fibrillose ringzone. It is a species of the sandy areas of the Great Hungarian Plain, occurring often and in great numbers. In Hungary, it grows mostly in Populus forests, but it can be found also in Junipero-Populetum

, in planted sandy pinewoods (

Pinus nigra

, P. silvestris

), and in open sandy steppe-grasslands (

Pestucetum vaginatae danubiale

).
