Images of British Lichens

Leptogium burgessii (L.) Mont.

Thallus gelatinous, lobes greenish to dark brown, convoluted, with abundant folioles (small, leaf-like structures) produced from the surfaces and margins, lower surfaces minutely pubescent; apothecia frequent, with red-brown to dark brown discs and with margins beset with abundant folioles, giving the apothecia the appearance of tiny, jelly sunflowers. On mossy, shaded, nutrient-rich trees and rocks, especially in old woodland in the oceanic west, a 'Celtic rainforest' species.

I am not a fan of newly made up, so-called 'common names' for lichens, which take at least a generation to become commonly understood and lack the necessary precision usually provided by Latin names. However, to me, and perhaps forever only me, this is the 'Jelly Sunflower Lichen'.
