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.
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
Thank you very much for your answer.This rare species is first for me.
Best regards
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
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
