Saccobolus caesariatus confirmation

Chris Yeates, 04-11-2021 15:26

Bonjour tous

I am fairly confident about this but would welcome a second opinion. As you can see this is a rather rich collection on dung of mountain hare, Lepus timidus; growing with Schizothecium (all checked so far are S. tetrasporum) and a Dactylella-type species which I think is fungicolous rather than a nematode-trapper.

The "starry" like appearance of the apothecia is particularly obvious when they are younger.

The hair-clusters are generally more acute than in the image here. Spore-clusters fit well with van Brummelen's "Type II" and the size does as well: 36.3-41.3 x 14.3-16.1µm - so too small for S. versicolor. Most apothecia seem to remain white, but a few acquire a light violet flush. Van Brummelen does not mention this but he does say he had not examined many collections and those mostly of single apothecia.

Amities, Chris

Re : Saccobolus caesariatus confirmation

Good evening Chris!

Very beautiful species, a real pleasure under the bino and the microcope. I had made a file on Ascofrance some time ago.

Amitiés.

Michel.

Re : Saccobolus caesariatus confirmation

Many thanks Michel.

Yes, your pictures were very helpful in making the identification. I see there is a pale violet shade to one of the apothecia there as well. It seems to be rare - certainly rarely recorded - in the UK.

Cordialement, Chris

Re : Saccobolus caesariatus confirmation

Hello, Chris and Michel,

thank you for the pictures of this very nice and rare species.

I found Saccobolus caesariatus only two times in Germany and I want to add with some more pictures of this interesting member from the Ascobolaceae.

Norbert
