Dasyscyphus virgineus for Confirmation

[RobSutton]

I got this down to Dasyscyphus virgineus but having only access to limited literature on these type of things (Fungi of Switzerland and Ellis and Ellis) I thought I'd just check that there isn't anything else it could be:





Thanks

looks OK Rob

what's it on? beech mast? that is a typical substrate for Lachnum virgineum

features include:
no crystals on the hairs which are generally cylindrical, but may be a little swollen at their apices . . .

the paraphyses, which are lanceolate - up to 5µm wide - and project well beyond the asci (I know that's a feature of "Dasyscyphus" in general, but but is very noticeable in this species)

cheers

Made a note of the corrected name - thanks Chris.

Paraphyses certainly seem to fit:


but the hairs did seem to have a few crystals on them and all were distinctly swollen:


It was growing on beech mast.

I think that's OK - paraphyses spot on (though a touch redder than we get them in this part of Yorkshire)

and I don't think those count as crystals at all - just gunk! Lachnum brevipilosum (= Dasyscyphus brevipilus) is also white, but has filiform to very narrowly lanceolate paraphyses)
