white Lachnum on Pinus cone

Bonsoir tousI expected this collection to be a straightforward Lachnum virgineum, but it lacks the prominent lanceolate paraphyses of that species and, along with other characters, the spores differ.
Apothecia clustered towards the proximal end of a cone of a Pinus sp. (planted, non-native).
Asci 8-spored, J+ (MLZ used here - a slip, I had intended Lugol), croziers present (arrowed).
Ascospores ellipsoid-fusoid 10.5-11.7 x 3.4,3.8µm (Qe = 3.1).
Hairs ornamented along full-length, cylindrical, not expanding at apex.
Ectal excipulum of very small,rather thick-walled, and narrow cells, becoming maze-like at junction with stem, and very narrowly parallel in stipe (see images).
Any suggestions and/or help very welcome.
Chris

Re : white Lachnum on Pinus cone
Hi Chris
I am sorry i cannot name this with confidence. And I overlooked your posting.
The hairs clearly point to L. virgineum. With this DCI contrast and the high resolution it is a bit difficult also. The asci were not alive? Are only a few mature? Spore number does not seem to be reduced?
maybe the paraphyses are slightly lanceolate? I still guess it is a misdeveloped L. virgineum.

Re : white Lachnum on Pinus cone
Thanks for that Zotto
I can see that my confusion was understandable. It may have been exaggerated by the fact that the specimen has been incubated for a while in the fridge and may well have developed atypically - there were, in addition, some abnormal spores which I ignored.
best wishes
