Abstract

The genus Disciseda in Poland until now was represented by two species: Disciseda bovista and D. candida. During the mycological investigations on the macromycetes fungi in the xerothermic grasslands of the Nida Basin, a species new for Poland from this genus, namely Disciseda verrucosa, was recorded. The basidiocarps of this species were found in the village Gacki (50°26'41" N, 20°36'34" E; ATPOL square Fe 24), in the village Wola Zagojska (50°26'41" N, 20°36'34" E; ATPOL square Fe 24), and in the Krzyżanowice Reserve (50°27'13" N 20°33'36" E; ATPOL square Fe 14), in the Ponidzie region. The basidiocarps of D. verrucosa were collected in the xerothermic grass, within Festucetum pallentis and Sisymbrio-Stipetum capillatae associations in the neighborhood of Festuca pallens, Stipa capillata, and Thymus marschalianus. On the basis of collected basidiocarps, macro- and microscopic characteristics were described and compared with other European Disciseda species. An identification key to the species of Disciseda occurring in Poland is given.

Highlights

The genus Disciseda is in the whole world represented by 15 species [1]
The basidiocarps of Disciseda verrucosa were collected during the mycological investigations carried out in the xerothermic sites of the Nida Basin (SE Poland)
The laboratory studies were carried out using the light microscope, scanning electron microscope (SEM), and the standard chemical reagents (10% KOH, JKJ)

Summary

Introduction

The genus Disciseda is in the whole world represented by 15 species [1]. In Europe, about five species were found [2,3], whereas in Poland, Discidea is represented by two species: D. bovista (Klotzsch) P. Both species in Poland belong to a highly endangered fungi, and classified to the category endangered – E [5]
