Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

I've never.........

I've never seen this in the field before. It has a worldwide distribution - but the bright blue colour looks almost too exotic to be a resident of britain!

see link below:

I think this species may have been reclassified as Terana caerulea? Anyone know??

reverted classification

The name has actually reverted to whence it came. Here's a bit of fungal nomenclature:
The species name is the 'type' of the genus Terrana which was established by Michel Adanson in 1763 (Terrana caerulea based on Byssus caerulea Lam. 1779). The type species of the genus Pulchericium is Pulcherricium caeruleum Parmasto 1968, which is also based on the same Byssus caerulea Lam. 1779. In other words Parmasto needlessly repeated a job that had already been done 189 years earlier. By the rules of the International Code of Botanical Nomenclature (ICBN) Adanson wins and Terrana caerulea is the correct name. It is an obvious nomenclatural mistake by Parmasto and so there's probably a deeper story here as to why it was ever called Pulchericium. Anybody?!

and the deeper story is ...

Adanson's introduction of Terrana in 1763 was based on a plate in a book by Micheli: Nova Plantarum Genera 1729. Unfortunately the plate in question has two different fungi on it. It needed some later detective work to clarify which element the name Terrana referred to, which is why it ended up with another generic name of Pulchericium (see Julich, Taxon, 1983, p480, for the deeper story).
I expect nobody wanted to know that! But it does point out that there is a nomenclatural side to mycology that involves a lot of detective work with ancient rare books - and that can actually be quite interesting (to some).
