Vasas, Gizella: Interesting macrofungi in Hungary VI. Four rare basidiomycete species

Stem: 5-10 cm high, 1-2 cm wide, cylindrical, tapering towards base, firm, solid. Colour creamy rose, sordid white, and often ochraceous rose or rosty ochre towards base. It is whitish furfuraceous below the cap, with water droplets exuded in wet climatic conditions. Flesh: rigid, fibrillose. Colour similar with the outer surface of the fruitbody, rose in the central part of the cap, paler to whitish towards the edges. Scent mostly pleasant, sweet; no characteristic taste. Spores: elliptic, 7-9 x 5-5.5 pm. Spore powder white. Herbarium specimens: Vendvidék: Szakonyfalu, Luzulo-Fagetum. Leg., det.: G. Bohus and M. Babos, 03.10.1963.

Lactarius hysginus (Fries ex Fries) Fries Very rare in Hungary, in the Hungarian red list of macrofungi (RIMÓCZI et al. 1999) it is listed among the critically endangered species near extinction (CR, category 1). Altogether six specimens are kept in the Hungarian Natural History Museum (BP). Up to 1989, this species was known from two localities (BABOS 1989), and it was observed only four times in the last 10 years in Hungary. These were collected in two, isolated regions of Hungary: (1) the Őrség, and the Vendvidék at the foot of the Alps in western Hungary, and (2) the Zemplén Mts in northeastern Hungary at the margin of the Western Carpathians. Although these areas are far from each other geographically (ca 600 km), their climatic and edaphic features are similar (e.g. highly acidic soil), therefore the macrofungi compositions of these areas are rather similar. Lactarius hysginus has a rather wide distribution in the Northern Hemisphere (East Siberia, Japan, North America, West, Central and North Europe), thus it is widespread. However, in this vast area of distribution it is rare and critically endangered and in the areas where it is recorded the state of habitats is declining (KRIEGLSTEINER 2001). It is found in collin and montane habitats, under conifers and birch (BASSO 1999), preferably in well-lit parts of the forests (forest margin, walking path) and
