A new locality record of a rare fungus Cercopemyces rickenii (Agaricales: Tricholomataceae) in Ukraine

Abstract

Cercopemyces rickenii (Bohus) Dima & L. Nagy (Agaricales: Tricholomataceae) is a rare species red-listed in Ukraine and in a number of other countries. Before now in Ukraine, the fungus was recorded in five localities, only in the steppe zone. All known localities were confined to sandy soil and plantings of Acer tataricum L. or Robinia pseudoacacia L. It is reported about sixth record of C. rickenii, located outside the steppe zone and the most northern in Ukraine. The fungus was found here in plantings formed by Caprinus betulus L. and Acer platanoides L. on forest soils. Using scanning electron microscopy, it was shown that the spore surface of C. rickenii had tuberculate ornamentation. In addition, it was shown that the basidium of the fungus could have more than four sterigmata.
