Claussenomyces is a genus of fungi in the family Helotiaceae. Species grow as saprophytes on decaying and decorticated wood, cones, or sap. Fruitbodies are turbinate (having the shape of an inverted cone) to pulvinate (shaped like a cushion), measuring up to 0.6 mm in both height and diameter. The flesh has an elastic to gelatinous texture.[1]


A 2008 estimate placed 19 species in the genus.[2] As of January 2015, Index Fungorum lists 16 species of Claussenomyces:[3]
