Siller, Irén, Vasas, Gizella , Pál-Fám, Ferenc , Bratek, Zoltán , Zagyva, Imre; Fodor, Lívia: Hungarian distribution of the legally protected macrofungi species

Hungarian red list category: 1. Justification: Its habitats, "acidic forests" with Sphagnum, have been depleting for various reasons: improper forest management and timber-extraction, decrease of water level and eutrophication of the peat bogs. Known Hungarian records: BABOS (1989): Csaroda (in sphagneto), Csömör (in sphagneto), Törökbálint (in silva mixta), Szalafő (in piceeto), Kelemér: Mohos (in sphagneto). RIMOCZI (1994): Kelemér (Luzulo-Quercetum subcarpaticum). Private collection of L. Albert and B. Dima: Mátra: Sirok: Nyírjes-tó (sub Betula pubescens). Leccinum variicolor Watling (Boletales, Boletaceae) Cap: 5-10 cm in diameter, convex, greyish brown, mouse grey or near to blackish brown, covered by paler (whitish, ochraceous) patches. Surface uneven, felty. Margin involuted for long and most often paler. Hymenium: whitish, cream, flesh brown when old. Its pores also whitish when young, then soon become dirty white, with ochraceous patches when pressed or old. Stem: slim, slender, but thick enough, therefore seems to be robust. Surface pale grey, ornamented with tobacco grey scales. It takes a striking bluish grey colour. Flesh: white, in cap soon becoming pink on cutting, in lower part of stem turning bluish green in spots. Scent, taste not too characteristic. Life-strategy: mycorrhiza (with various species of Betula). Occurrences in Hungary, habitats: September-October, in wet peat bogs, under Betula at the edge of fen woods. Distribution, frequency: Recorded from North America, the Far East and Europe. Rather frequent in Northern Europe, rarer towards south and limited to peat bogs (KRIEGLSTEINER 2000). Hungarian red list category: 2. Justification: Endangered because of the global drying out of wetlands (KRIEGLSTEINER 2000). Similarly to other Leccinum species, it is edible (and thus collected). Known Hungarian records: BABOS (1989): Őrség: Szalafő (in silva mixta), Bakony: Öcs, (in sphagneto), Uzsabánya, Kelemér: Nagy-Mohos (in sphagneto). RIMOCZI (1994): Farkasfa: Fekete-tó (in silva mixta). VASAS and LOCSMÁNDI (1995): Farkasfa: Fekete-tó. ALBERT et al. (2004): Bakony: Öcs: Nagy-tó,
