ni-hegység: Nagybózsva: Szőlőske-hegy (Querco petraeae-Carpinetum), Mátra: Nagylápafő (Luzulo-Fagetum subcarpaticum), Vendvidék: Felsőszölnök. Gyrodon lividus (Bull.) Fr. (Boletales, Paxillaceae) Cap: 6-15 cm diameter, yellow to brownish red; surface slimy when wet, skin easy to peel. Tubular part: long decurrent; yellow when young, then greenish yellow, finally greenish brown, becoming blue when wet; difficult to separate from flesh. Stem: cylindrical, slim, slightly tapering at base, often curved; its colour same as that of the cap, ornamented more or less with longitudinal filaments. Flesh: soft in cap, hard, filamentous, fibrous in stem; pale yellow, soon becoming blue, then rust-brown when cut; scent and taste is acidulent. Life-strategy: mycorrhiza (under Alnus spp.). Occurrences in Hungary, habitats: July-October, in wetlands, in fen-woods, under Alnus. Distribution, frequency: Found but rare all over Europe, since its habitat, the wet, seminatural alder woods are declining. So far not known outside Europe (KRIEGLSTEINER 2000). Hungarian red list category: 2. Justification: Its habitats are in danger, therefore the distribution of the species is also declining. The diminution and desiccation of alder woods is the main threat for the fungus. The species is edible, fleshy and very attractive; however, because of its rarity, it should not be collected; collecting for any reason should be banned.
