Parmelia sulcata?

Observed: 11th December 2012 By: jakermanjakerman’s reputation in Fungi and Lichensjakerman’s reputation in Fungi and Lichens

Found on fallen oak twig. Looks like it might have been colonised by an alga? The margins are dark brown to black in places, like the edges of burnt paper - is this normal?


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

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

It's incredible how many interactions there can be on a single twig! A lot of the lichens I've come across have various other things growing on them, which makes them harder to identify for a beginner like myself! I'm gradually starting to recognise when a sample has been colonised.
