White discomycete on Alnus cones
Khomenko Igor, 21-01-2021 03:47
Khomenko IgorHi,

I found this small white discomycete on Alnus incana cones on the ground.

Pictures are here: https://www.inaturalist.org/observations/59289600

Apothecia 0.5-0.6mm, some with a long stipe.
Asci 8-spored, IKI+r or IKI+b after KOH, croziers(+), 90-118x9-11um.
Ascospores biguttulate, measure
(15) 15.5 - 18 (18.9) × (4) 4.2 - 4.7 (5.1) µm
Q = (3.3) 3.4 - 4.2 (4.4) ; N = 31
Me = 16.7 × 4.4 µm ; Qe = 3.8
Paraphyses with long, cylindrical VBs.


I presumed it could be Pezizella/Calycellina alniella, but the spores size and shape, IKI reaction and some other thing do not look right and I run out of ideas.


Any help would be greatly appreciated.


Regards,
Igor

Re : White discomycete on Alnus cones
Hi Igor

it took a while until I realized the apical ring of Pezicula-type. This is an Allophylaria (close to Calycina), and it comes close to a sample on twig of ?Pistacia lentiscus by Ruben Martinez-Gil posted in 2017.


But i think the spore ends are too acute in your sample.

In my Allophylaria folder it is called "woody"

Re : White discomycete on Alnus cones
Thank you Zotto for all your help. Indeed, it looks very similar to the other members of this genus.
