Physcia adscendens

About

Physcia adscendens, the hooded rosette lichen, is a species of foliose lichen in the family Physciaceae. Originally described in 1882, this widely distributed lichen is characterised by its distinctive hood-shaped lobes that curl upward at the tips and long dark-tipped hairs growing from underneath. The species has a broad ecological tolerance and can colonise various substrates, from limestone monuments to tree bark, contributing to its success as a pioneer species following environmental disturbances.
