Hymenoscyphus caudatus / sparsus ?
Patrice TANCHAUD, 29-11-2016 17:53
Bonjour,

récolte sur débris de feuilles, probablement de chêne vert. Asques à base simple, spores 15,5-17 x 4,5-5 µm.
Merci d'avance pour vos avis.

Re : Hymenoscyphus caudatus / sparsus ?
Difficult to say. I think caudatus but not sure. Why are there no asci near the paraphyses? H. sparsus has VBs more restricted to the apex and less scutuloid spores, also I think never so long apo stipes.

Re : Hymenoscyphus caudatus / sparsus ?
Only paraphyses because young apothecia without asci.

Re : Hymenoscyphus caudatus / sparsus ?
o.k., but with 400x it is too small to see details. The paraphyses are empty here.

Re : Hymenoscyphus caudatus / sparsus ?
oui, c'est bon!
I feel the VB region is too long to  match H. sparsus.

Merci bien Zotto. Thanks for all !
