The wood is not beech

Thank you for your opinion. There is no beech in Hayley Wood. It is most likely to be oak judging by the appearance although ash is the most abundant tree.

ID

OK, I have modified the ID.

I should say that when I first looked at the photograph, my instant ID was L. brevipilosum, and THEN I looked for evidence of the wood being beech. Perhaps I looked too hard.

However, L. brevipilosum does occur on wood of other trees, oak included. Nevertheless, I would not record the species myself without checking it with a microscope, especially if not on beech, so a more fence-sitting ID seems appropriate.

L. virgineum, as well as being a shaggier species, is essentially a species of vegetable debris - mostly dead herbaceous stems, but also on beech cupules and very small trigs. It is at best very unusual on more solid wood.

Thank you for spending time on this

If I were able to find it again, what specimen would be required, how should it be preserved and what would you look for with the microscope?
As far as I can tell, no species of Lachnum had been recorded from Hayley Wood by 1975 (Oliver Rackham's book). Lachnum niveum has not been recorded from Cambridgeshire [Lachnum niveum (as Dasyscyphus niveus), 07/09/1974, England, Cambridgeshire (VC: 29), Monk's Wood NNR, TL1980, coll.: anon, id: anon, Lit. rec., FRDBI Record No.: 131693 is, of course, Huntingdonshire]. Lachnum brevipilosum has four records (http://www.fieldmycology.net/FRDBI/FRDBIrecord.asp?strVC=29&strName=Lach...). Thanks again, Martin
