Marja PennanenHello,I have found some scanty yellow Hymenoscyhus
Bonsoir à tous,Pouvez-vous me donner une piste pour ce Ciborinia greffé sur sclérote noir en forme de banane, trouvé en aulnaie à ail des ours dans un mélange de matière organique (feuilles) pourrissantes et terre mêlée ?
a) asques IKI+
b) spores étroitement ellipsoïdes à ovales : 9-12,5x2,5-4,5
c) certaines spores présentent une enveloppe hyaline qui se détache (cf. spore1)
d) paraphyses filiformes, septées, certaines flexueuses au sommet
e) excipulum à textura globularis
Bernard
Hi Bernard,
can you tell us how many spores are in the asci? In your picture I see 4, but the foto maybe shows not the whole ascus.
Regards from Lothar
This is usually 4-spored but 8-spored apothecia also occur. Uwe Lindemann wrote an article on it for which I also supplied data. here attached.

I'll check the number of spores per ascus in 30 minutes.
Bernard
I redid one preparation and I have predominantly observed 4spored-asci but sometimes with 3, 5, 6 or 8 spores !
Here are some more pictures of spores and paraphyses. Paraphyses are slightly swollen at the top and the spores are finally : 6-13x2,5-4,5
Bernard
Nuclei are difficult to see. usually staining with IKI helps.
