Reddening asco
Bregtje Miedema, 05-02-2020 11:19
Goodmorning,

From the Leeuwarder bos (Leeuwarden, Netherlands) a small asco, very reddening, no stipe. Asci IKI+, Croziers+, biserate, 70-95 x 6-7 µm. Parafyses septate. Spores with at least two drops and mostly 1 sept. 11-13 x 2-3 µm.

Can someone tell me what species this is (maybe Calycina?) ?

Thank you and kind regards,

Bregtje Miedema

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.


 


Amitiés. Michel

Re : Reddening asco
Goodafternoon Michel,

Here are some pictures made in water.

Maybe that helps.

Thank you,

Re : Reddening asco

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.

Re : Reddening asco
Hello Michel,

Here some pictures made in Cottonblue and KOH 5%.

I do not have Cresylblue.

Re : Reddening asco

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.

Re : Reddening asco
Hello Michel,

These two pictures are from the least red asco left, in water.  The asco's are getting in a rather bad shape now, if they weren't already.

Re : Reddening asco

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

Thank you for your help, Michel.

It was a very interesting puzzle.

Kind regards,
