Lachnellula suecica ?

Sur branche morte de Mélèze. Les ascospores sphériques sont typiques, mais la dimensions des spores indiquées dans la Clef de Declercq me fait hésiter (Spores subspherical, 6-7x5-6 µm)
(4,5) 4,7 - 5,3 (5,5) × (4,3) 4,5 - 5,2 (5,3) µm
Q = 1 - 1,07 (1,1) ; N = 20
Me = 5 × 4,8 µm ; Qe = 1

Re : Lachnellula suecica ?
My key says for suecica *4-7(-8) x 4-6 µm, and in 1984 I wrote 4-6 x 4-6 µm, and the same I find in Raitviir 1980. The Declercq key I do not know, is there a link?

Interesting to know would be if the ascus apex reacts hemiamyloid (in Lugol or after KOH in MLZ) or is permanently inamyloid. This variation is mentioned in my key on my homepage, which I just noticed is again out of order.

Re : Lachnellula suecica ?
Very good, this is the typical situation of L. suecica.
