New localities of Protostropharia alcis (Basidiomycota, Agaricales) in Poland
The present paper provides new records of <em>Protostropharia alcis </em>in Poland. So far this species was known in the country only from several latest localities in the Biebrza National Park (Biebrza Basin) and the Kampinos National Park (Warsaw Basin). The new localities are situated in the Wigierski National Park (the East Sudetian Lake District) and in the north-western slope of Mt Wierzejska (the Holy Cross Mountains), where <em>P. alcis </em>was collected on dung of herbivores (eurasian elk and red dear) within several types of forest communities. All specimens of <em>P. alcis </em>were collected in recent years, from late September to early October, in the period 2012-2013. A full description and illustration of <em>P. alcis </em>based on gathered collections are given. Its delimitation, the knowledge of its ecology, general distribution, and threat is also briefly discussed. Based on the new and known distribution data for <em>P. alcis </em>in Poland, its red list category is proposed.
