Abstract

Results of mycological investigations conducted in xerothermic grasslands of the Nida Basin in the years 1984–2013 are presented. Our research brings up to date the current knowledge on ecological requirements of threatened species of macrofungi. Strong affiliations between macrofungi and specific phytocenoses of the alliances Festuco-Stipion and Seslerio-Festucion duriusculae were detected. A considerable influence of the occurrence of certain species of steppe fungi on the composition of the mycobiota in the Nida Basin was identified.

Highlights

This group of fungi belongs to the following genera: Disciseda (D. bovista, D. candida), Gastrosporium (G. simplex), Geastrum (G. campestre, G. minimum, G. schmidelii) and Tulostoma (T. brumale, T. kotlabae, T. melanocyclum, T. squamosum)
Tulostoma squamosum is an indicator of Festucetum pallentis, Tulostoma kotlabae is an indicator of Koelerio-Festucetum rupicolae and Geastrum minimum, Gastrosporium simplex, Disciseda bovista and Tulostoma melanocyclum are indicators of Sisymbrio-Stipetum capillatae (Tab. 3)
The following conclusions can be drawn from our studies: (i) observations conducted at burnt plots of Sisymbrio-Stipetum capillatae showed a complete disappearance of macrofungi

Summary

Introduction

I.e., fungi having similar morphology, species clearly attached to xerothermophilic habitats, were prioritized for selection in our studies This group of fungi belongs to the following genera: Disciseda (D. bovista, D. candida), Gastrosporium (G. simplex), Geastrum (G. campestre, G. minimum, G. schmidelii) and Tulostoma (T. brumale, T. kotlabae, T. melanocyclum, T. squamosum). The. Tomaszewska et al / Selected macrofungi as bioindicators of xerothermic communities association Tulostomato (brumali)-Gastrosporietum simplicis, which exhibits a strong relationship with habitats of xerothermophilic grasslands of the alliance Festuco-Stipion, is a good example of such a specialized mycoassociation. (i) to analyze the occurrence of ten selected rare and protected species of fungi in chosen communities of xerothermic vegetation in the Nida Basin by correspondence analysis;. (iii) to identify bioindicator species within fungi examined by us whose occurrence indicates an undisturbed type of communities of xerothermic vegetation
