Analysis of diversity of wood-inhabiting fungi retrieved from a Mediterranean forest dominated by Pinus pinaster Aiton

The present paper is focused on the diversity of wood-inhabiting fungi in a poorly investigated habitat: a Mediterranean forest dominated by maritime pine. The sampling area lies in Tocchi biogenetic Reserve, located in the province of Siena (Tuscany, Italy). The monitoring campaign was carried out in 10 permanents plots, taking note of all the fungal species found on each piece of dead wood, irrespective of size and stage of decay. Over one year of surveys, 56 taxa of wood-inhabiting fungi were recorded, among which 39 are corticoids species, 16 polypores and 1 Heterobasidiomycetes. The fungal community seems to be dominated by a small number of species, which are more abundant than the others. Moreover, there are some specific features of deadwood influencing the species composition, such as the presence of coarse woody debris at the first decay stage and fine woody debris at the late decay stages. The results allowed characterizing the wood-inhabiting fungal community in this forest reserve, broadening our knowledge on several species and providing a preliminary database for further studies in Mediterranean areas.
