# Heterodermia

Heterodermia is a genus of lichenized fungi in the family Physciaceae. The genus has a widespread distribution, especially in tropical regions, and contains about 80 species.

## Description

Heterodermia are subterranean or almost upright leaf lichens with a bearing diameter of up to 10 centimeters. Their top is pale greenish, whitish or pale greyish, many species are ciliolate on the edge. The underside is white, tan or orange with pale or dark rhizines.
Lichenoverruculina is lichenicolous (a parasitic fungus that only lives on lichen as the host) and is found under the thallus of various Heterodermia species.

## Distribution

The genus Heterodermia has about 80 species a large area of distribution, especially in the tropics.
