Bonjour Bregtje,

These reddening apos remind me of Calycina heterospora but Congo red is not the best to observe cells contents (in spores and paraphyses) .

Indeed the spores would be septate and with oil drops in C. heterospora.

I am not sure from image 10 but spores in image 11 could fit .

I join pictures showing paraphyses and ejected spores in water and paraphyses content un Cresyl blue.

Michel

Cotton blue and KOH kill cells and do not bring valuable information in that case.

From image 15 , though, one can see that excipulum cells would match Calycina's , as on this picture in water.

Michel

You are right, Bregtje, the apos were already in a rather bad shape and cells appear dead now . I'm afraid these last pictures will not allow more to say.

Amitiés. Michel
