Аннотация:Fungus spores resembling teliospores of the genus Nyssopsora (Pucciniales) were found in a sampleof Sakhalinian amber. Morphological features of the spores in the examined amber sample in general correspondto description of teliospores of the extant species Nyssopsora trevesiae parasitizing host plants of theAraliaceae, Trevesia sundaica in Java and Sumatra and Brassaiopsis ciliata in Southern China. It can beassumed that the plant on which those teliospores formed most likely belongs to the Trevesia–Brassaiopsisgroup. Extant species of these genera are characteristic of the undergrowth in humid forests from the Himalayasto Indonesia, which supports paleofaunistic data on rather warm and humid climate of Sakhalin amberforest.
