A reevaluation of predatory orbiliaceous fungi. II. A new generic concept

A new genus concept is proposed for predatory anamorphic Orbiliaceae in whi ch the trapping device is the main morphological criterion for the delimita tion of the genera. Molecular, ecological, physiological, biological, and f urther morphological features are taken into account as well. Following the groups identified by Hagedorn & Scholler (1999), these predatory fungi are divided into four genera: Arthrobotrys Corda forming adhesive networks, Dr echslerella Subram. forming constricting rings, Dactylellina M. Morelet for ming stalked adhesive knobs, and Gamsylella gen. nov. for species producing adhesive columns and unstalked knobs. Eighty-two species are accepted, for 51 of which new combinations are proposed.
