Porina sudetica - a lichen



Range & Status

In Britain this species is known from only two sites, both on the Land' s End Peninsula. Elsewhere it has a scattered distribution in central Europe. At its Cornish sites, one of which is a SSSI, P. sudetica grows on soil, mosses and plant debris on metal-rich spoil from old mine workings. The main threat to this species is the landscaping of derelict mine sites. Apparently this lichen has not been recorded from these sites for some time and survey work should be undertaken to refind it, to estimate its population size, and any potential threats.
