Contribution to morphology and ecology of Polyporus rhizophilus

摘要

The distribution and ecological conditions of the occurrence of Polyporus rhizophilus in Poland are discussed. The species was previously known from only one locality in Dwikozy near Sandomierz. Further localities were found on the roots of Stipa capillata in the Skorocice reserve near Busko Zdrój and at an anthropogenic site among Dactylis glomerata, Poa annua and P. trivialis grasses in an urban park in Końskie. The latter locality is noteworthy as it is situated outside the occurrence range of xerothermic grasslands in the Wy?yna Kielecko-Sandomierska upland. This locality is isolated ecologically from the two remaining Polish localities situated in the xerothermic grasslands.
