Lots of small whitish cup-like ascomata with short hairs on the outside, growing on hygric deciduous wood. Collected almost a week ago (December) in southern England.
I have tried to use the 'Key to European species of Lachnum' by H.O. Baral (2006?).
Some distinguishing characters:
• Hairs with oxalate crystals -, paraphyses with strongly refractive VBs -, croziers + (subkey 5).
• Spores cylindrical to fusoid, oil content 0-?1,
(4.8) 5.2 - 6.4 (6.9) × (1.8) 1.9 - 2.2 (2.3) µm,
Q = (2.3) 2.4 - 3.2 (3.3) ; N = 30,
Me = 5.7 × 2.1 µm ; Qe = 2.8.
• Hymenium white going ochraceous.
• Paraphyses slightly protruding (~7 µm in one area measured), widths 2.6 - 3.5 µm (N = 10), lanceolate, generally cylindrical but occasionally inflated towards apex
• Hairs mostly with inflated apex.

Re : Lachnum sp.
Yes, I see no reason to doubt. Croziers are clear, lack of VBs, small spores, longstipitate white apos getting only yellow.

Re : Lachnum sp.
Thank you for confirming, and for another very useful key that enabled me to identify the species.
