Lichen: Placynthium nigrum

Lichen: Placynthium nigrum

I know lichen are an acquired taste and that people, in general, prefer the more exotic wildlife; orchids, for example, or the more dramatic animals such as birds of prey. I do my best to try and enthuse people with these lower organisms which are all too often over looked but I can find little to say in support of Placynthium nigrum!

It is a dull, black crust that grows on hard calcareous substrates and so it is very common on walls and tombstones. Apart from being black and crusty there is little else one can add really! Looking at it, it is hard to believe it is actually a living thing, it could just be some sort of powder someone dropped accidentally. However, it is a living organism and if you look at under magnification it is far more interesting. Why not take a look?
