VASAS Department of Botany, Hungarian Natural History Museum H-1476Budapest, Pf. 222, Hungary; vasas@bot.nhmus.hu Boletopsis leucomelaena, a macrofungus rare in all its range, this time is reported from Hungary for the 3rd time. Surprisingly it was found in acidic beech forest environment, a habitat type not previously reported in references. Key words: Boletopsis leucomelaena, Hungary, red list of Hungarian macrofungi INTRODUCTION Discussions on rare and interesting macrofungi collected in Hungary have been presented in several publications (VASAS and ALBERT 1990, VASAS et al. 1990, 1991, LOCSMÁNDI et al. 1993, VASAS 2002, 2004). The present paper is the seventh of the series, which from its beginning intended to publish data on rare Basidiomycetes included in the red list of the Hungarian macrofungi (RIMÓCZI et al. 1999) or suggested for inclusion. The present article deals with Boletopsis leucomelaena (Pers.) Fayod, a species rare in Europe and in its entire range of occurrence, and included among the red listed species in Austria, the Czech Republic, Germany, Poland, and Slovakia (HROUDA 2005^). Similarly, the Hungarian redlist of macrofungi (RIMÓCZI et al. 1999) also contains it as an endangered (EN, category 2) species. From Hungary, the first reports on this species were very recently published by ALBERT and DlMA (2007) who refer to Boletopsis leucomelaena as being found for the first time in Hungary by Vajk Erdei on October 24, 1998 in the Visegrád Mts near Szentendre in acidic Fagetum (Luzulo nemorosae-Fagetum sylvaticae). The next report is dated as October 5, 2005, when László Albert and Bálint Dima found the species in the same mountain range near the village of Tahi on acidic soil under Fagus sylvatica trees in Luzulo nemorosae-Fagetum sylvaticae, where sessile oak Studia Rotanica Hungarica, 39, 2008 Hungarian Natural History Museum, Budapest
