Hi Bernard,

Some of the spores seem immature but it seems OK for G. cookeianum.

Best wishes,

Charles.

Hi Charles,

Great thanks for your answer !

Best regards,

Bernard

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.

Ah OK, Charles,

Great thanks for these further information

Best regards,

Bernard

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

Thank you very much, Luc ! Very interesting !

Best regards,

Bernard
