Thank you for your opinions.
I often use focus stacking for laboratory work in super macro, but never tried it in the field. I will do in the future, thank you.
I am perfectly aware of the diffraction, and from time to time I try shots with wider aperture... But in this particular kind of imaging depth of field is very important. So when it comes to choose the best image between the shots, I always tend to pick the one with f/22 or f/16... despite of a certain loss of detail! And focus stacking would be a solution.
 

Maybe this image feels a little crowded, but the aim was to show every aspect of the fungus and so I'm rather happy with the shot.
The smaller ones have a bilobate shape, somewhat like a close mouth. Then they become cup-shaped with a short stalk. Afterwards the stalk become longer and stouter and the "head" (better called apothecium) become saddle-shaped, and in the end bilobate-compressed towards the stalk.
The problem is when you only find one or two... Not always easy to identify if you don't know the species well enough.
The hazelnut in the background is a trick to better understand both the habitat and the size of the subjects.
Shot with Micro Nikkor AF 60 D at f/22, 1/3 sec.

you get a lovely scene with a practical purpose of an erudite and scientific nature,

Soaring...

cute, as long as they do not chew something of your camera
