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.
As many will know, this is actually a lichen, one of the few in which the fungal partner is a toadstool. The rest of the lichen is the granular algal mat, in which the algal cells are held together in a fungal matrix.
The characters of the toadstool are well shown in Mushroom Lady's photos - the red-brown area at the top of the stem, and the stem itself matt and very minutely pubescent.
I am a bit doubtful about some published pictures, in which this species appears to be confused with non-lichenised Omphalina and Arrhenia species, so it is good to see this observation. It should serve as a reference for "good" Lichenomphalia umbellifera (formerly known as Omphalina ericetorum).
I wasn't even certain of the ID.
