Ecobiogeographical research of desiccation tolerant non-lichenized fungi from the phylum Ascomycota in the Croatian forest ecosystems has started in 2010. It is mainly focused on pedunculate oak (Quercus robur L.), a tree species that plays an important economic role. Desiccation tolerant (xerotolerant) fungi are taxonomically and ecologically very poorly known ecological group of fungi. They live in aerophytic synusia (dead branches and bark still attached to plant individual) extremely exposed to atmospheric and cosmic influence. These fungi normally survive complete loss of their chemically unbound water and are capable to continue with all their metabolic functions after rehydration. The aim of this research is to explore biodiversity of desiccation tolerant fungi on pedunculate oak and to determine their possible bioindication value since their ecology is very similar to lichens that are already proved to be excellent bioindicators (e.g. for detection of air pollution and other anthropogenic influence, overall habitat quality assessment etc.). The present research is performed both in the field on the selected plots (sampling) and in the laboratory where morphological, cytological, histological, ecological and biostatistical methods are applied. Quantitative biodiversity analysis will be conducted by determining species-area relationships and spatial modelling of biodiversity parameters as a function of environmental variables. Preliminary results based on 6 plots on selected locality show relatively high biodiversity of fungi with 40 identified species from overall 760 collections. They belong to the orders Helotiales, Orbiliales, Mycocaliciales, Rhytismatales, Dothideales, Lecanorales, Sordariales and Xylariales.
