Stanowisko Hapalopilus croceus (Phanerochaetaceae, Polyporales) w rezerwacie „Las Natoliński” w Warszawie

This paper presents data on a new locality of Hapalopilus croceus in the “Las Natoliński” nature reserve in Warsaw (Fig. 1). This species is strictly protected in Poland and is included on the Red list of the macrofungi in Poland with the category E – endangered. In Poland, H. croceus occurs on old oaks (Quercus), mainly in protected areas (national parks, landscape parks and nature reserves) or on trees that are natural monuments. The basidiomata of H. croceus were found on an old dead oak tree (Fig. 2). This is the second locality in Warsaw where this fungus has been found; until now, H. croceus was only known from the “Las Bielański” nature reserve.
