Bonsoir tous
this fungus developed on incubated sheep (Ovis aries) dung after 2-3 weeks. It grew on both the dung and the paper on which the dung was placed.
During development the ascomata were a bright lemon-yellow, this has faded somewhat as they matured. They started out globose, then barrel-shaped, finally to the shape which can be seen in the accompanying photographs. A noticeable feature is that they are now ± stoutly stipitate. This shape is very like that ilustrated in Doveri (central image) and also by Ann Bell in her "An illustrated guide to the coprophilous Ascomycetes of Australia"
The ascopores are marked with irregular cracks, without any longitudinal / parallel / anastomosing ones. Spore measurements are 19.1-20.6 x 9.7-11.2µm, which correspond perfectly with those given by van Brummelen, and lie between those given by Doveri and Bell.
In the light of all the above I am fairly confident that this is Ascobolus michaudii; as this would be new for me (and there are few UK records) I would be grateful for any comments from those with experience of the species.
Amitiés
Chris

Re : Ascobolus michaudii?
Good evening, Chris!
Very nice pictures! Your description seems to correspond well to A. michaudii as well as the ornamentation and shape of the spores. Indeed, some apothecies can develop a kind of foot, sometimes with age. It is not a very frequent species (at least for my harvests), but despite everything it appears regularly in small numbers.
Amicalement.
Michel.

Re : Ascobolus michaudii?
Good morning Chris,
I found this species several times and I think you are right with A. michaudii. Compare also the paraphyses wirth the fig f, g in the monograph off Van Brummelen (page 114). See my pictures below.
