<i>Phaeocalicium populneum</i>, a saprotrophic fungus rediscovered in Poland

The saprotrophic fungus <i>Phaeocalicium populneum</i> was noted from Poland only from one confirmed locality at the end of the 19th century, from the vicinity of Żagań (SW Poland). A new locality of this species is presented, which was found in 2017 on the bark of <i>Populus nigra</i>, within the Puszcza Darżlubska Forest in northern Poland. The species is common in Europe, and we consider that <i>Ph. populneum</i> is not rare in the country,
