J'ai également trouvé ce Lachnum sur Filipendula. Les asques ont des crochets à la base et mesurent 50-65 ?m de long. Les paraphyses sont lancéolées. Les spores sont hyalines et mesurent 9,5-15 x 2 ?m. Lachnum nudipes me semble être un bon candidat. Je lis qu'il est fréquent sur cette plante. Y est-il strictement lié ? Si oui, d'autres espèces du genre peuvent-elles venir sur le même substrat ?

Re : Lachnum
It seems there are croziers, though I do not see it clearly. First you must verify whether there are crystals among the hairs. A closeup of the hairs would be welcome.
The only alternative to probable L. nudipes (which has croziers) is the little known L. morthieri but your large spore measurements exclude this.

Re : Lachnum
Hi Robin
I suspect that Zotto wanted more to see crystals and not hair.
To be sure that it is L. nudipes, the presence of crystals must be stated.
Look at my site, pictures number 02 and 06 (at the bottom of the page).

Without the presence of crystals it cannot be confirmed that it is this species.
