I warmly ask for your opinion on this collection.

Re : Ascobolus folliicola?
Hi Patrik

Spore dimensions are provided in PDF.
Me = 18.8 × 9.5 ?m; Qe = 2
Spores very uniform. I have not met with a length of more than 20 microns.
I didn't measure ornamentation.
With Ascobolus I have no experience, so any tips are welcome.
Thank you
Mirek

Re : Ascobolus folliicola?
Hello Mirek

A.folliicola normally has a small stalk at the base of the apothecium and a well marked and overflowing margin. Compares with A.crenulatus, the substrate is not well defined.

Re : Ascobolus folliicola?
Hello Michel.

I am not sure if it was this species but A. crenulatus probably already microscopic. It seems to me that the spore ornamentation is definitely finer and denser. (see pictures)

The fruiting bodies now harvested grew on the ground, covered with a thick layer of mulch and leaves falling from trees.
Maybe this is the reason for their unusual appearance?
Thank you and best regards.
