Fruiting body an aethalium with a thin, thick or sturdy cortex that breaks open irregularly. Hypothallus inconspicuous or consisting of interwoven white strands and forming a border around the fruiting body. Pseudocapillitium either emerging from the base in the form of strongly branched threads sometimes fraying from the plate-like lower portion or filling the entire aethalium with perforated membranes. Spores free or clustered, brown, yellow or olive in mass.
Nine species have been described in this genus (Lado 2001), and two of these have been reported from New Zealand.
