Rhytidhysteron rufulum / viride ??
Miguel Ángel Ribes, 13-04-2008 16:49
Miguel Ãngel RibesHi. This is my first time. I hope do it not so bad. I am writing from Spain.

Small fructifications, 4-3 x 3-2 mm, coffe-shaped when dried, more or less cup-shaped with moisture, exterior black and greenish himenium, hard, probably in fraxinus wood. Dark brown spores, slightly alantoide-shaped, with 3 septum, thick walls and septum, narrowed at septum. Asci mainly moniliform, inamiloid. Parafisis with a lot of septum, nearly moniliform, the top covered with a yellow substance and amiloid the rest.

Sporal measures
23,4 [27 ; 28,2] 31,7 x 7,4 [8,9 ; 9,4] 10,9
Q = 2,4 [3 ; 3,1] 3,7 ; N = 49 ; C = 95%
Me = 27,58 x 9,11 ; Qe = 3,05

Asci measures
169,6 [177,6 ; 185] 193 x 9,3 [11 ; 12,5] 14,2
N = 10 ; C = 95%; Me = 181,33 x 11,73

Thank you

Je relance le message de Miguel car je trouve sa récolte intéressante et j'aimerais aussi en savoir plus, grâce à l'avis de personnes expérimentées sur le sujet . R. rufulum me semble être une hypothèse sérieuse.

Re:Rhytidhysteron rufulum / viride ??
Thank you Alain. ;) I have read the tipical hymenial color of R. rufulum is red, but it can be more or less greenish. In the other hand, I have no documentation about R. viride, but the species name seems to oriented to green color, isn't it ????
