tral, and Northern Europe. In Central Europe with montane, subalpine distribution, in Switzerland it reaches 1,800 m above sea level. Hungarian red list category: 2 (protection category at generic level). Justification: The species is endangered both at international and national level. It is in latent danger because of its rarity, but in acute danger because of the fertilisation of pastures and change in land use (KRIEGLSTEINER 2001)! Throughout Europe, but mainly in Denmark, England and Germany Hygrocybe species have a great importance in nature conservancy (KRIEGLSTEINER 2001). Habitat declining and fertilising its habitats reached such a level that this aesthetically pleasing species (Hygrocybe calyptriformis) requires urgent protection. Listed among the proposed species for protection in Europe (DAHLBERG and CRONEBORG 2003) by the European Council for Conservation of Fungi. Known Hungarian records: ZAGYVA (2000): Vendvidék: Kétvölgy (Nardo-Callunetum). Private collection of L. Albert: Vendvidék: Kétvölgy (NardoCallunetum) (ALBERT 2000). Private collection of L. Albert and B. Dima: Vendvidék: Kétvölgy (Nardo-Callunetum) (ALBERT and DIMA 2005). Hypsizygus ulmarius (Bull.) Redhead (Agaricales, Tricholomataceae) (Syn.: Lyophyllum ulmarium (Bull.) Kühner) Cap: 5-25 cm, hemispherical to expanded and flattened, may be depressed or slightly umbonate in the middle; edge involuted for long; surface marbled at the beginning, later smooth, shiny; cream or ochre, occasionally with yellow tints. Gills: dense, whitish cream, decurrent. Stem: 6-15 x 1-3 cm, cylindrical, in groups, may be curved, may be excentric, same colour as cap, with longitudinal filaments. Flesh: white, fibrous, thick, with pleasant scent and taste, sometimes with distinct flour-smell. Life-strategy: necrotrophic parasitic and saprobiont. Occurrences in Hungaiy, habitats: from July to October, oak-ash-elm gallery forests and seminatural beech forests, however, it also occurs in more open sites, parklands and roadsides. On standing but decaying snags, thicker stumps, trunks. Its frequent substrates: Fagus sylvatica, Ulmus, Populus and Quercus species. Distribution, frequency: Holarctic, lowland and montane species. Known in Northern Asia, North America and Europe. In Europe it is reported from Southern and Southeastern Europe (Italy, Romania), Western Europe (France, The Nether-
