Grey and green foliose Lichen found on a Cherry tree on all sides. Noticed they tended to be on profusion's.
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
You seem to have been very busy searching out lichens!
I don't know if the Neighbourhood Nature course encourages students to attempt to identify species they find or does it just ask that observations be posted on iSpot for identification?
If the course encourages an attempt at identification a very useful (and simple to use) key to some of the common species on trees is available on-line from the Natural History Museum.
Its called A Guide to Lichens on Twigs and might be worth bookmarking:
The lichen in your RH photo should key out easily, though the lobes are usually yellow rather than greenish-yellow .......
Thanks for the link, will have at go at identifying the different species. This task was more about identifying the different types and the type of surface, direction they were facing etc.
