Fungus gnats are somewhat similar to mosquitoes, but if you look closely, they lack the long, straight sucking proboscis that biting mosquitoes have. Most of the fungus gnats have a large swollen chest area, the head is small and is attached far down the front of the chest, so that the fungus gnat looks hunchbacked. The species are more or less brown-yellow in colour.
It is a species of fungus in the family Hygrophoropsidaceae. The fruit body is yellow–orange, with a funnel-shaped cap up to 8 cm across. The thin gills on the underside of the cap run partway down the length of the otherwise smooth stipe.
