Arachnopeziza delicatula
Louis DENY, 06-04-2026 11:07
Bonjour forum,

Trouvé sur bois de feuillu très dégradé cette arachnopeziza, qui ressemble à A. delicatula des dossiers de Zotto. Les spores plus courtes et plus larges m'ont l'air caractéristique. (Caluler le nombre précis de septa m'a été impossible)

J'ai lu sur ce forum des discussions sur la distinction A. delicatula/A. aurata.

La question est-elle tranchée: A .delicatula est-elle une ''bonne'' espèce?

Merci de vos lumières

Re : Arachnopeziza delicatula
At first glance yes, but I remember the issue is difficult. I think Kosonen treats the species in his paper.

Re : Arachnopeziza delicatula
I have struggled with the distinction between A. delicatula and A. aurata.  I have these comments handy on my desktop:

"[A. delicatula] can be distinguished from A. aurata by the width of the spores that are on average wider in A. delicatula (3 – 3.5 ?m wide in the longest spores) and by the Q-value that is in average less than 20 in A. delicatula and above 20 in A. aurata."

"We suggest that A. aurata is distinguished from A. delicatula by narrower, pointed and straight or curved spores, with regularly 6–7 septa."

Re : Arachnopeziza delicatula
Zotto, Ethan,

Thanks for your adice and information.
I will then call it delicatula.

Re : Arachnopeziza delicatula
yep, I agree on delicatula. The spores of aurata resemble long (e.g. Pinus) needles. The difference is clear once compared side by side.
