Cheylimenia sp ?? ou autre genre ??

Bonjour à tous

Quelques petites apothécies blanchâtres avec poils marginaux bruns de 2 à 4 mm de diamètre.

En macroscopie j'ai songé au genre Trichophaea ou Paratrichophaea; mais la microscopie me fait plutôt penser au genre Cheylimenia. D'autre part peut-il exister des Scutellinia de forme "albinos" ??

Mon manque d'expérience en la matière me porte à faire appel à vous. Merci de me mettre sur la bonne voie.

Hi Alain,

These probably are immature apothecia of Paratrichophaea boudieri.
Can you provide us with some microscopical data?

P. boudieri has hairs with different kind of bases.
You should also see hairs with a truncate, tapered or bulbous base.

Kind regards,

Ron

Hi Ron & hi to all

Other images and microscopical data.

Is the new images convincing ?? Is this pseudohairs a good feature for Paratrichophaea boudieri ??

But I have not examine under a microscope the hair withe buble base.

asque ; 220-230 x 12-14 µm

spore; 15-18 x 9-10 µm

Oh I am sorry for the images

Re : Cheylimenia sp ?? ou autre genre ??

Hello Alain,

The pseudohairs are indeed typical for P. boudieri.

Sporesize is rather small, perhaps due to immaturity.

The shorter hairs towards the apothecial base are often (not always) with a bulbous base.

You should examine fully mature specimens if possible.

All the best!

Ron
