Panellus ringens and P. violaceofulvus (Agaricales, Mycenaceae) from Slovakia: morphological and ecological aspects

Abstract

Species Panellus ringens and P. violaceofulvus are similar in some respects and different in others. They look alike macroscopically, especially in having pleurotoid habit and violet-brown and/or red-brown colours of basidiomata, but differ microscopically, distinctly in size of spores. For each species, description and illustration of macroscopic and microscopic characters are provided based on the Slovak collections. Some misidentifications are mentioned and crucial morphological characters stressed. Compared and commented are also the characters used for differentiation of both species in the selected literature. The added distributional and ecological data concern the area of Slovakia and Europe. Panellus ringens is proposed to be included in a new version of the Red list of fungi of Slovakia.
