Abstract
Ektomikoriza je mutualističen odnos med micelijem glive in drobnimi koreninam gostiteljske rastline. Gomoljike prestavljajo pomembno komercialno vrsto ektomikoriznih gliv, ki jo na naravnih rastiščih v Sloveniji najdemo pogosto in v velikem številu. Znanje o pojavljanju gomoljik in drugih gliv v njihovi združbi na naravnih rastiščih je manjše, za razliko od poznavanja združb v nasadih gomoljik v tujini. V študiji prikaujemo prvi primer analize združbe ektomikoriznih gliv na naravnih rastiščih poletne gomoljike (Tuber aestivum) vSloveniji. Cilj naše študije je bil analizirati združbo ektomikoriznih gliv na naravnih rastiščih poletne gomoljike pri dvez različnih drevesnih partnerjih v simbiozi, pri hrastu in belem gabru. Za namen identifikacije gliv v združbi ektomikoriznih gliv na rastiščih smo uporabili tako anatomsko-morfološki kot molekularni pristop. Ektomikorizo poletne gomojlike smo našli v večini vzorcev tal, medtem ko je bila vrsta Cenococcum geophilum prisotna v vseh vzorcih. Russula spp. so se pojavljale le s hrastom, Tometellaspp. pa pretežno z gabrom. Primerjava združb z združbami ektomikoriznih vrt v producirajočem nasadu poletne gomoljike v Italiji je pokazala, da se združbi bitsveno razlikujeta, saj so vrste, ki se pojavljajo vobeh primerih le polenta gomoljika, ter vrsta iz rodu Terzetta in Tomentella.

Abstract:
An ectomycorrhiza constitutes a mutualistic relationship between the mycelium of a fungus and the roots of a host plant. Truffles are important commercial ectomycorrhizal fungi, naturally present and abundant in Slovenia. The knowledge about their distribution and presence of associated fungi is scarce for natural sites but well defined for several truffles plantations established abroad.The study is the first example of the ectomycorrhiza community study from natural truffle sites in Slovenia.We aimed to analyse the ectomycorrhiza communities of natural Tuber aestivum sites from under two common ectomycorrhizal plant partners: hornbeam and oak. We have applied morphological and molecular approach in ectomycorrhiza identification to reveal the community structures. Tuber aestivum was observed in most soil samples in natural stands. Cenococum geophylum was present in all. Russula spp. only occurred with oaks while Tomentella spp, were more common with hornbeam. In comparison with truffle plantation, the community was different with only several in common, such as T. aestivum, Tarzetta sp. and some Tomentella species.
