In September 2005, whitish, cushion-like structures of a fungus were found in pupal chambers of the eightspined European spruce bark beetle (Ips typographus) in Donnersbachwald (Styria). Based on morphological characteristics the fungus was identified as the basidiomycete Gloeocystidium ipidophilum that has occasionally been reported as associate of Ips typographus in various parts of Europe (Poland, Germany, Norway and Austria). The fungus is illustrated and a brief review of the scant knowledge on the taxonomy, biology and ecology of Gloeocystidium ipidophilum is presented. The symbiotic relationship between Gloeocystidium ipidophilum and its vector is also reviewed. While the fungus clearly benefits by being transmitted to appropriate habitats by the spruce bark beetle, the significance of the fungus for Ips typographus is less clear. The common occurrence and intensive sporulation of Gloeocystidium ipidophilum in pupal chambers of Ips typographus might suggest that teneral adults feed on the fungus during maturation feeding. The ecological significance of Gloeocystidium ipidophilum for the spruce bark beetle deserves attention and further study.
