Bonjour à tous.
Récolté sur Rubus fructicosus le 4 février 2016.
Diam. 0.5 mm.
Sessile, tôt pulviné, blanchâtre, rougissant et enfin brunissant.
Asques octosporés avec crochets : 85 - 100 x 9,4 - 13, IKI +
Spores fusiformes multiguttulées, comportant une cloison à mâturité, enrobées d'une gaine: (19,3) 21,4-23,4 (24,6) x (4,5) 4,7 - 5 µm
Paraphyses contenant des vacuoles réfringentes.
Quelques poils épars, hyalins.
J'ai bien une idée mais cela ne correspond pas macroscopiquement.
Merci de votre aide.

Camille

Re : Sur Rubus
Dear Camille

The endless Calycina saga, and an interesting species that I do no know.

I think the "poils" are ascogenous hyphae.

Some Calycinas show such reddening indeed.

my C. subparilis is similar but has smaller spores and an IKI-red apical ring.

To see the ring-shape better you should take a photo of a dead ascus.

Is it from Belgium?

Re : Sur Rubus
Dear Zotto.

Vielen Dank fur ihrer Anwort.
The collection comes indeed from Belgium (South of Brussels).
How could I "kill" the ascus? Using Melzer?
Kind regards.

Re : Sur Rubus
for example by stronger pressure on the cover slip, this is the easiest way. Or when you wait some minutes after adding Lugol. Also by drying the preparation and later adding water may kill the asci.

Re : Sur Rubus
Hello again Zotto.

Herewith the ring-shape as you told me to do.

Best regards.

Re : Sur Rubus
Yes, this is helpful, you see the ring and apical wall around is thicker, and the cytoplasm detached.

But with so large spores I know nothing.

Many thanks for your help Zotto.
