Bonjour, Je vous envoie ces images d'un échantillon de Lachnum, trouvé sur une brindille de Corylus, dans une forêt humide des Pyrenées catalanes.
Coupe 0,8-0,9 mm diamètre. Pied 0,5-0,6 mm d'haut.
Asques 34,8 – 40,8 x 5,1 – 5,5 µm.
Spores 7,7 – 10 x 1,5-2,7 µm.
Poils avec incrustations, légèrement élargis au sommet, 25,7-28,2 x 2,6-3,3 µm.
Paraphyses terminées en point, 53,7-53,9 x 3,7-3,9 µm.
Je pense en Lachnum crystallinum, mais je ne suis pas sûr du tout.
Merci d'avance pour votre aide,
Andrés
Hello Andres,
your Lachnum (s.str.) cannot be L. crystallinum (former Dasyscyphella crystallina) because of the hairs that are granulate to the top. Further, this species grows on Quercus only (?).
Which Lachnum you have found is difficult to say, because we for instance do not know if there are croziers at the base of the asci.
As I see, the paraphyses do not contain (many) vacuoles, and there are no crystals on the top of the hairs.
Best, Lothar
Thank you very much for your answer.
I add two more photos, of the squash of the asci. Luckily I think I could have seen some croziers... and a paraphyse with more vacuolar content?
Best,
Andrés
About the hairs, it's the length that I could measure, from the top of the hair to the most dense and colored part (I can't ruled out that they will continue in this part). I'm going to try to separate these hairs.
