Re : Chalazion?
Very rare kind, I think it is indeed Chalazion, even if your mushroom lacks maturity, you can check the amyloidity of the hymenium as well as the coloration of the warts of the spores in the cotton blue. Normally C. erinaceum, on excrement, has smaller spores, the other known species are terricolous. Peter Welt put a message on Ascofrance in 2009 on this genre. www.ascofrance.com/forum/8486/pezizales

Re : Chalazion?
Hello Michel,

I did have some problems with the calibration of the camera, so here are the correct measurements:

Apotheca: 162x117 um

Asci: 8-spored; 62.8x25.8 um

Spores: 16.4-16.9x9.8-10.2 um; covered with fine warts.

Paraphyses: septated; 2.3-2.7 um tops 3.7-4.1

With these values I would go for C. erinaceum
