Asco in Greenhouse
Sebastien Basso, 05-06-2023 14:02
Hello,

I try to identified all mushroom species I found in a tropical greenhouse , Lyon Downton / France.

I have an asco found I thinl 'but not sure) a leaf or a plant)  , not that sure, that was dried, totally impossible to really identiy the plant , there are soveral species from around the world.

I am not a professional, I have the scope I have , ascii are IKI+ ,some with crozier, spores are ellipsoids and mostly "biguttulated".

I attached all what I have , if you need more information , I will need to wait they are back, dried species are very little.

any helps or idea is welcomed.

thanks

Spore size :

(6,8) 7,4 - 9,4 (10,8) × (2,2) 2,4 - 2,8 (3,3) µm
Q = (2,1) 2,7 - 3,6 (4,2) ; N = 50
Me = 8,4 × 2,6 µm ; Qe = 3,2

Re : Asco in Greenhouse
Hello Sebastien,
with this macroscopy it should be a Sclerotiniaceae. It is long ago (in the 1990s), but I once found in a greenhouse Moellerodiscus lentus (then determined by Zotto!). I do not have a clear notion of the paraphyses by your pictures. If there is a bright yellow content in living specimens this could be useful.
Yours, Lothar
P.S.

Re : Asco in Greenhouse
I tentatively agree with Lothar, given that the microscopy was done from the dried apothecium (or mounted in something like KOH, for the spores I guess they are not alive, not to speak of the rest). The iodine looks to me more like Melzer's.

Re : Asco in Greenhouse
Yes it was mounted into Melzer , spore in water (from a spore print) and the rest true, somewhat dried.

Thanks
