# Chaenothecopsis

Chaenothecopsis is a genus of about 40 species of pin lichens in the family Mycocaliciaceae.

## Taxonomy

The genus was circumscribed in 1927 by Finnish lichenologist Edvard August Vainio, with Chaenothecopsis rubescens assigned as the type species.

## Ecology

Many of the species are resinicolous, meaning they grow on conifer resin or other plant exudates. Most common host plants are trees in the genera Abies, Picea, and Tsuga. In contrast, Chaenothecopsis kilimanjaroensis is a lichenicolous lichen, meaning it grows on the thalli of other lichens–sometimes as a parasically, sometimes commensally.
