Fungus with strange circle on the cap found under Birch in a plantation over coal slag.
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.
consider this observation along with http://www.ispot.org.uk/node/236057
it might just be a frost affected lactarius or brown roll rim or could be something else but i am wondering how much we are seeing is the true nature of the fungus and how much is due to being affected by frost or being past its best. if it is past its best it might be impossible to say what it is.
did you have the impression that they were past their best, were they soggy, had there been a frost?
Both of those were compared off line prior to submission. The positive ID i did myself was done via a partial name and a brows through other observations. The "dip" in the cap did it for me. On the other the rim did not appear to be rolling and there was no Dip in the cap. Fly Agaric is collected by drug addicts and i do not get much chance to do pictures. It was about 150 yards away from the Roll rim i did an ID on and about 50 yards in the opposite direction from the younger one in the third and fourth images. Frost is off the list. I walked from south to north and the image numbers and time are used to get the pin positions on the map. It was closest to the pore fungus i observed.
