Bonne nuit à tous.Apothécies récoltés le 12-1-2014 dans une dune fixée, en croissant dans des groupes serrés dans un chemin avec Pinus pinea et cistáceas à la proximité, jusq'a de 1 cm. de diamètre, avec un estipe immergé dans le sable.
La microscopie m'amène à Discinella boudieri, mais je remercierait votre confirmation.
Merçi en avance.
Amitiés,
Tomás Illescas
Buenas noches a todos:
Apotecios recolectados el 12-1-2014 en duna fijada, creciendo en grupos apretados en un camino con Pinus pinea y cistáceas en las cercanías, hasta de 1 cm. de diámetro, con un estipe inmerso en la arena.
La microscopía me conduce a Discinella boudieri, pero agradecería vuestra confirmación.
Gracias y un saludo,
Tomás Illescas

yes, this is D. boudierii. Typical is the reddish IKI reaction of apical ring (blue after KOH). The asci should arise from croziers.
Some of your spores are dead (those in IKI and those which contain elongate, non-globose oil drops). They might be a little smaller than the living.
A plate of mine is in the paper on Roseodiscus formosus by Wischollek et al.

Is it usual that hairy furfuraceous margin and sides?
Best wishes.
yes I think so. Not sure whether D. menziesii and D. boudierii are synonyms but they are very very similar. Here a photo identified as menziesii.

here a collage from D. boudieri from our distrikt. In the background the biotope, naked sandy soil, and in the neighborhood Octospora humosa (to see), Peziza, badia, Deconia montana, Pholiota mixta...... To see the hairy and furfuraceous margin too. Conspicous by all our finds are the presence from Cytisus scoparius.
Greetings Peter.

The photos of microscopy are realized on one of the most developed specimens, almost immediately after the recollection, and I noticed that there were some dead spores
Curiously, yesterday I checked another specimen, after almost two weeks in the refrigerator, and all the spores that I saw were alive.
Thank you and a greeting,
Tomás Illescas
