Dark cap. Pores, not gills. Grey markings on stem. Cap up to 10cm. On cut grass under birch.
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 Flaxton says, L. roseofractum is currently rated a synonym of L. scabrum. And also, as he says, this could be L. variicolor. We need information on the flesh colours after cutting.
So why have I added agreement to Thistle's original ID? In the last few days, we have had a lot of both L. scabrum and L. roseofractum under birches on our University campus, coming up near each other, but looking as distinct as they always do, and in the exact same places as they always are. I have not seen whatever paper describes the DNA research that lumps them together, but to my eyes there are consistently two entities, and not just on our campus.
