Observations on Cordyceps riverae (Hypocreales, Ascomycota) in Croatian caves.

This paper appears to be the first contribution on cave macromycetes in Croatia. During the systematic biospeleological field work in the Dinaric karst area, eight more or less stable populations of the entomogenous species Cordyceps riverae Pacioni (Hypocreales, Ascomycota)have been located since 1990. Some 200 speleological sites have been visited so far in order to find both living and/or infected hosts, with 69 sites colonized by two subtroglopilic lepidopteran species of the genus Triphosa (Geometridae) which are apparently the only surely known hosts of the fungus. C. riverae was collected from five localities (situated in Gorski kotar, Kordun and Dalmatia regions) out of eight speleological sites in which the species was recorded. A full description of C. riverae, a comparison with the holotype collection, detailed ecological observations, as well as the mapping of known distribution of both the species and host are given. C. riverae is recorded in Croatia for the first time.
