Trametes achracea

Found on beech branch. Layered in various colours


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

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

Have you a photo of the pores?

Photo of the pores

Sorry I haven't got a photo of the pores. When I took that picture i'd only just started to learn the proper way to identify fungi for my course.

Wrongly named

There is no such thing as Trametes achracea. I assume that the intended ID was T. ochracea.

However, I think it is more likely this is T. versicolor, though I cannot be positive and prefer not to add a revision. As Flaxton has already said, a view of the pores could be useful.

If the poster has good reason to name this as T. ochracea, I suggest he/she adds a new revision him/herself.

Wrongly named

In reference to your comment about the there is no such thing as Trametes achracea. Have a look at the Collins Complete Guide to British Mushrooms and Toadstools where you will find the scientific name has not been abbreviated.

Thank you for the suggestion of T. versicolor, However I dont think its Turkeytail.

My edition of Collins has Trametes ochracea so perhaps you have an earlier version with a typo. Yours does look very like the illustration for T ochracea but you can see the attachment of the bracket to the log in the book is only in the centre.
shows how variable both species are.

I maintain my opinion

Being as we cannot now cut a cross section of the fungus to look for presence or absence of a black layer in the upper cortex (characteristic of T. versicolor), or else measure the spores, the identity of the fungus cannot be confirmed either way.

However, the two currently authoritative monographs on the polypores (Ryvarden & Gilbertson, European Polypores, vol. 2, and Bernicchia, Polyporaceae s.l., Fungi Europaei vol. 10) both emphasise the yellowish brown to brown colours of the zones in T. ochracea, without strongly contrasting colours, and the photographs in the latter book support the habit differences of the two species. The link Janet has posted above shows the typical appearance of T. ochracea.

In so far as these can be named simply from photographs, I maintain that the photograph here is more likely to be T. versicolor (though the two species are undoubtedly confused and I am not being definite).

I have to say that I am also wondering if the cortex and spores of the specimen shown in the so-called "Complete" Guide were ever checked. It is certainly not typical.
