Non loin de la mer, dans une panne dunaire, en pelouse à épervières piloselles (Hieracium pilosella) sur sable coquillier. Pas de soies.Je pense à Geoglossum cookeanum mais je ne vois pas très clair entre G. cookeanum et G. similie (si cette espèce existe vraiment) ?
Merci d'avance pour vos avis !

Re : Geoglossum cookeanum ?
Hi Bernard,
Some of the spores seem immature but it seems OK for G. cookeianum.
Best wishes,
Charles.

Hi Bernard,
Regarding G. simile, I'm not familiar with that species but it seems to prefer a swampy habitat, unlike yours. It also has a squamulose stem.
Regards,
Charles.

Re : Geoglossum cookeanum ?
Hello,
Geoglossum simile is a species of peat bogs; grows between sphagnum.
In Geoglossum cookeanum the upper cells of the paraphyses have clear constrictions at all septa, forming pearl necklace chains (moniliform chains), consisting of spherical, egg-, club-, pear-, barrel-shaped to cylindrical cells.
In Geoglossum simile the upper cells of the paraphyses have clear constrictions at the septa usually every two or three septa (see drawings). The paraphyses are only slightly widened; possible presence at the top of 1 (or 2) barrel-looking, septate double cell(s) (see drawings).
Another species, G. uliginosum is closely related to G. simile (one species?). In G. uliginosum many (not all) paraphyses have a pear shaped to spherically widened top cell (see drawings).
Kind regards
Luc Lenaerts
