Hi Michel! Great documentation! We would like to feature this spotting but for this we would need individual images to fit our format. You can have a total of 6 images per spotting. A least one individual image of the whole mushroom would be great, like the one you have on the bottom right. Thanks in advance!

No, Interestingly not! Probably because they appeared to be growing directly from clay on a fairly disturbed habitat. The mycelium might not have had the time to form an ozonium or I simply didn't see it or it may even be a collection without ozonium, which is also possible.

Nice. No sign of ozonium?
