Stalk usually at least 66% of the total height, black, consisting of netted fibres at least at the base. Columella reaching at least half way up the sporotheca but usually almost reaching the apex, where it merges into the capillitium. Capillitium forming a dense internal flexuose net with the main branches connected to the columella along its whole length, often forming a surface net in the basal part, around the top usually with loops and free ends. Spores lilac-brown, with a small, pale, rounded germination pore, verruculose, 7.5-9.0 µm diam ( )


Members of this family typically have dark coloured spore mass. The typical type of fruiting body produced is a stalked sporangium. A capillitium is always present and many species have a prominent columella ( ) ---- dead wood
