Studia bot. hung. 35, pp. 59-66, 2004 INTERESTING MACROFUNGI IN HUNGARY VI. FOUR RARE BASIDIOMYCETE SPECIES G. VASAS Department of Botany, Hungarian Natural History Museum H-1476 Budapest, Pf. 222, Hungary; E-mail: vasas@hot.nhmus.hu Four rare species (Hygrophorus aureus, Hygrophorus poetarum, Lactarius hysginus, Phaeolepiota aurea) of the Hungarian red list of macrofungi (Basidiomycetes) are discussed. Phaeolepiota aurea is recorded in Hungary for the first time. Key words: Hungary, Hygrophorus aureus, Hygrophorus poetarum, Lactarius hysginus, Phaeolepiota aurea, red list of the Hungarian macrofungi INTRODUCTION Discussion of rare and interesting macrofungi collected in Hungary were presented in several previous publications (VASAS and ALBERT 1990, VASAS et al. 1990, 1991, LOCSMÁNDI et al. 1993, VASAS 2002). The present paper is the sixth of the series. The compilation of the Hungarian red list of macrofungi (RIMÓCZI et al. 1999) has greatly stimulated the research and publication of the rare redlisted macrofungi of Hungary. Also the List is regularly revised, improved, and updated. Hygrophorus aureus (Arrh.) Fries Relatively rare in Hungary, in the Hungarian red list of macrofungi (RIMÓCZI et al. 1999) it is listed among the endangered species (EN, category 2). Altogether four specimens are kept in the Hungarian Natural History Museum (BP). The species was known from three localities before 1989 (BABOS 1989), i.e. from the Őrség (Farkasfa) and the Sopron Mts (Brennbergbánya) in western Hungary, and from the Visegrád Mts (Pilisszentkereszt) in the central part of the country. H. aureus was not reported for 14 years in Hungary, until it was discovered in a coniferous forest at Galgagyörk in November 2003. H. aureus is a very characteristic species with reddish orange cap and very viscid fruitbody, appearing in coniferous woods in late autumn. The identification is relatively easy because of its characteristic features. There are two similar species: H. hypothejus (Fr. ex Fr.) Fr. and H. speciosus Peck, however, the latter has not yet been found in Hungary. The colour of the cap is the same as that of H.
