Lepraria rigidula?

Not sure if my suggestion is correct so any comments will be great, thanks. Thallus, a pale-green seems to be growing over a Physcia sp. (I don't think it is actually part of the Physcia sp.), found growing on a wooden post.


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

Valid suggestion, but ...

I think the granules are too fine and too massed together to be L. rigidula. I see no sign of the long projecting hyphae of this species, though the photograph would have to have high resolution to show them.

L. rigidula seems to demand cleaner air than some other Lepraria species; your site looks a bit too urban for it in my own experience.

I am not saying you are wrong, but I think it is more likley to be the common, urban and rural, L. lobificans. It has the 'spongy' look of that species.
