Dacrymyces stillatus. J2. capitatus P.. d ictyosporus . Dacryopinax spathularia. Cerinomyces ceraceus and Calocera cornea and _C. 1utea caused considerable decay of wood. Dacrymyces palmatus, _D. minor, _D. novae-z el and iae and Calocera v is co s a also decayed wood to a significant extent. Four distinct types of decay were noted; three types of brown-rot and one type of white-rot. The brown-rotting strains were unusual in that some degraded considerable amounts of lignin. Monokaryons of Dacryopinax spathularia showed a reduced capacity to decay wood, while those of Dacrymyces stillatus and D,. palmatus did not decay wood. Types of rot associated wi^th species in the Tremellales and Auriculariales thought to be saprobic on wood are presented based on herbarium specimens.
