Crepidotus caspari.The Pale Oysterling
The Variable Oysterling, Crepidotus variabilis, is one of the commonest species around, however I have always seen it on fallen twigs or branches, i.e. deadwood.
So when I came across these growing on the branch of a living Willow it seemed reasonable to suppose that they might be something different.
The 2008 edition of Funga Nordica lists 15 species of Crepidotus, and has a key. After looking at the spores, shape of the cheilocystidia, and some discussions with Philip, I decided it was probably something called Crepidotus lundellii.
However, it didn't seem to be listed in any of my other books and I could find no records for it on the FRDBI.
I started thinking I might have something unusual or rare - - - the reality was far less exciting, it has been re-named as Crepidotus caspari, and I soon found enough information to confirm the identity.
That being said, there are only a tiny handful of records for this species in Wales, so a nice find and another new species to add to my list!
