Found in forest with Pinus halepensis, near to Olea.

asci (186.9) 192.9 - 220.1 (235) × (16.6) 19.4 - 21.2 (23.6) µm

spores (103.3) 110.7 - 135.7 (136.2) × (11.6) 12.9 - 13.4 (13.7) µm

Re : Geoglossum sp.
Try Geoglossum fallax. If not look if the ascus is amyloid or hemiamyloid

Re : Geoglossum sp.
Hi,

I think it's Geoglossum cookeanum, because of the 7-septate spores and the presence of much moniliform chaines in the parafyses. Difference with Geoglossum barlae sensu stricto with rotated, distorted and intertwined paraphyses and almost without clear moniliform chains in the paraphyses is sometimes difficult. In my opinion the spores here are not 110-135 µm long, but much smaller.

Kind regards
Luc Lenaerts

Re : Geoglossum sp.
Yes, Geoglossum cookeanum, the spore measures must be wrong.

Sabino.

Hi,

I agree with Luc and Sabino.
