Slimy blue-green mushrooms, about 4 cm diameter. Pinkish gills. Growing in waste grass between field and trees.
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.
Are there alternate names for this fungus? e.g. S.aeruginosa?
No. There are three very similar species S aeruginosa, cearulea and pseudocyanea and it is all down to microscope work. There are slight differences of habitat but not enough to make a definitive id possible.
Did it smell of pepper? Could be a clue.
Collins guide says S. aeruginosa has gills with white felty edges and white scales which adhere persistently to the slimy cap; S. caerulea lacks the white gill edges and any velar remains are normally confined to margin and soon disappear; S. pseudocyanea has a peppery smell. Weighing this up I agree with the ID of S. caerulea, though would feel even more enthusiastic with an ID of Stropharia sp.
