Conchomyces bursiformis is an indigenous, non-endemic fungus found throughout New Zealand on decaying wood especially that from beech trees. It has a smooth pale cream to light brown convex cap (>60 mm wide) which is attached to the wood by a very short stipe.
Gills and spores are white, close and radiating from the point of attachment out to the margins.

This fungus was growing on a dead tree branch in a damp area of the Te Henui valley.
