Rutstroemia calopus ?
Patrice TANCHAUD, 30-12-2013 10:29
Bonjour,

récolte réalisée sur le littoral, sur débris de plantes (herbacées ?). Spores 14,5-17 x 6-7 µm.
Jusque-là, je nomme de telles récoltes R. calopus (égal ? R. maritima).
Merci d'avance pour vos avis éventuels.

Hi Patrice
I wrote a long answer to your fungus but it disappeared although I saved it.

R. calopus , paludosa and maritima I know only from monocots. Yours is clearly a dicot. I had something in Somiedo on cf. Euphorbia, microsc. very similar bur macros. different (cubby folder "calopus cf., cf. Euphorbia").

Is the iodine reaction actually faint  in Lugol? It is hardly seen.

Miguel, do I have the article you mentioned? Can you send me?
Thanks
Zotto

Happy 2014.

Reaction with Melzer in the picture, but also faint with Lugol.
Thank Zotto for for your comments.
