Re : Stictis
Bonjour Javier,
Regarde du côté de Cryptodiscus rhopaloides, il me semble que la microscopie correspond assez bien. C'est une espèce assez commune sur écorce de feuillus. Les spores sont un peu grandes, mais j'ai aussi des récoltes avec des spores jusque 47 µm.
Amitiés,
Daniel

Hi Javier,
with these clavate spores (fig. 3) consider Cryptodiscus.

Martin
Update: Daniel seems to have the same thoughts. But I must admit that Zotto (in a circulating paper) excluded Cryptodiscus rhopaloides from this genus in his comments on Breitenbach&Kränzlin 1984, as well Baloch et al 2009 did.

Re : Stictis
Yes, there are two species rather common, rhopaloides and the less common idaei which has narrower spores than rhopaloides. Both are very closely related, and belong in Karstenia. By the way, Lugol provokes a red reaction to the entire hymenium, with a faint blue running ahead. After KOH treatment the hymenium stains deep blue in iodine.
My maximum was actually 50 µm, but with spores strongly clavate and hardly constricted at septa.
C. rhopaloides is also known as Ramonia interjecta, being probably erroneously thought to be a lichen.
