(foliose) jelly lichen found growing on the

Collema nigrescens is a leafy (foliose) jelly lichen found growing on the bark of trees such as bigleaf maples, in wetter coastal parts of California. It is commonly called button jelly lichen or bat's wing lichen. It is blackish-green when wet, and dark brownish-green to dark olive when dry. The photosynthetic partner is the Nostoc cyanobacterium that is spread throughout the thallus. Although foliose in form, like all jelly lichens, the thallus is not differentiated, lacking layers or an upper or lower cortex (lichen) and the cyanobacteria is spread throughout the thallus. It has dark purple-brown apothecia all over. It produces no reaction to lichen spot tests.

The A772 was a major A road located in Edinburgh, Scotland. The A772 was originally the A7 before a major renumbering of the roads into Edinburgh and also begins there, at a junction with the A701 in the neighbourhood of Nether Liberton. From this junction, the A772 heads south-east through Gilmerton, a suburb of Edinburgh. This part is known as Gilmerton Road and has a 30 mph speed limit. At the edge of Gilmerton, the road becomes Drum Street, where it passes The Drum, an 18th-century country house, before reverting to Gilmerton Road.
