New species of Laboulbeniales (fungi, ascomycetes) from Sulawesi, Indonesia

Four new species of Laboulbeniales occurring on beetles (Coleoptera) from Sulawesi (Celebes), Indonesia, are described and illustrated: Cucujomyces celebensis sp.nov. parasitic on Hyliota sp. (Cucujoidea, Cucujidae), Dimeromyces storkii sp.nov. parasitic on Eustra matanga Andrewes and Eustra plagiata Schm.-Goebel (Carabidae, Paussinae), Laboulbenia hammondii sp.nov. parasitic on Omadius spp. (Cleridae), and Rickia anthribidicola sp.nov. parasitic on Hypseus vestitus Jordan (Anthribidae, Anthribinae). All of the new species are compared with existing taxa. Of particular note is K. anthribidicola, which represents the first confirmed instance of parasitization by a laboulbenialean fungus on members of the hyperdiverse beetle family Anthribidae.
