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

Occurrences in Hungary, habitats: only two collections are known, in deciduous woods, especially under Fagus sylvatica. Distribution, frequency: Known from some European countries, North America and Australia. Infrequent in Europe. Hungarian red list category: 1. Justification: Very rare throughout Europe and often included in red lists. Macroscopically easy to confuse with other rare black Elaphomyces species. Known Hungarian records: HOLLOS (1911): Fraknó (sub Fagus sylvatica). BRATEK et al. (1999): Mátra: Parádóhuta (Deschampsio-Fagetum). Elaphomyces macidatus Vittad. (Elaphomycetales, Elaphomycetaceae) Fruit-body: subglobose, sometimes depressed, up to 22 mm diam., encrusted by a greenish later brown blackish mycelium. Peridium is nearly smooth, blackish with permanent verdigris large plaques. Gieba: at maturity filled with blackish brown spore mass. Spore: globose, brownish black, opaque at last, relatively large (28-35 ëm). Life-strategy: mycorrhiza. Occurrences in Hungary, habitats: This fungus has been found to be locally abundant (Somogyfajsz), but the number of known habitats is very low in Hungary and Europe. Distribution, frequency: So far not known outside Europe. Occurs only in a few countries and not frequent in any places. Hungarian red list category: 1. Justification: This species seems to be a European endemism. Macroscopically not easy to distinguish from the other rare black Elaphomyces species. Known Hungarian records: HOLLOS (1911): Litke (sub nom. E. septatus). SZEMÉRE (1965): Somogy megye: Somogyfajsz (Felsőkakpuszta, Kaszópuszta), Bakony: Eplény, Pénzesgyőr (sub Fagus sylvatica). BRATEK (unpubl.): Somogyi-dombság: Mesztegnyő (Querco robori-Carpinetum), Kóspallag (Quercetum petraeae-cerris).
