A Calycina-like tiny one
Michel Hairaud, 31-10-2021 12:13
Michel HairaudBonjour, 

Est il possible de m'orienter pour cette récolte sur Fagus dégradéavec ces seuls éléments et documentation de qualité médiocre :
Apos jaune de souffre, à marge non lisse, obconiques, jusqu'à 0,3 mm de diamètre. 
Asques IKI + de type Calycina, H+, à 8 spores, 70-75 x 8-11, PS 45-50. 
Spores septées, 18-20 x 3-4 µm, OCI = 4, ne devenant pas violettes dans le CRB, (sauf overmatures)
Paraphyses droites, cylindriques, avec 2 rangées de VBs. , x 3-4 µm 

Merci 
Amitiés Michel

Re : A Calycina-like tiny one
Hi Michel

I don't know why I missed your post. This is "Calycellina" ochracea, you find it in my Pezizellaceae folder under citrinula-ochracea.

Unsequenced species, of unclear generic relationship.

Re : A Calycina-like tiny one
Merci Zotto, 
It actually fits your folder samples which I had not seen.  
Calycellina was my first idea actually but I was not convinced by the BRC reaction on spores ,( only positive on some overmature spores in that collection) 
And as the collection was  rather poor , there is nothing correct  left for sequencing . 

Amitiés. Michel

Re : A Calycina-like tiny one
o.k., the species is not that rare. The guttulation like in Cyathicula is totally deviating from the Pezizellaceae as a whole.
