Lungwort lichen, plus the unseasonable arrival of spring

Lungwort: the lichen that Guy Stephenson saw at Gartan
Lungwort: the lichen that Guy Stephenson saw at Gartan

While on a walk at Gartan, by a much-flooded lake, I spotted some lichen on a branch brought down by Storm Desmond. The striking silver of its underside first caught my attention, and on turning it over I was surprised by the vivid green on the upper side.

The lichen is lungwort, ‘Lobaria pulmonaria’, which, because its shape resembled a lung, was thought to be a beneficent medicine. The lichen is a symbiotic partnership of a fungus, a green alga and a cyanobacterium. Lungwort is very sensitive to air pollution and grows only in the purest air.

Several letters record an unseasonable arrival of spring:

I noticed some trees along the Dodder that are budding already.
