Malcolm  GreavesI have been cultivating some Goose dung and this Ascobolus was quite frequent. It had the look of A albidus with its striate spores and gelatinous cap but they were too small at 16-19 long. This seems to point to Ascobolus sacchariferus but the literature suggests this is only found on deer dung.
Is it sacchariferus, a small version of albidus or something else?
Thanks
Mal

Re : ascobolus
Hello Malcolm.

Look for A.michaudii whose spores correspond better to your pics. Regarding A.saccariferus it can be found on substrates other than deer.

Re : ascobolus
Bonjour Malcolm et Michel, 

The substrate is mentionned to welcome A. brantophilus. Looking at the crevices on spore surface , I wonder whether this name could not be considered ? Though spores may be a bit too small.


Amitiés

Re : ascobolus
Thanks both. I don't know why I didn't consider A brantophilus, which I have seen before. The protruding asci look a better fit for that as well. I will try and go back and cultivate more and check my spore measurments again.

Re : ascobolus
Do you have access to wild goose or in farmyards or else, Malcolm ? 

I remember a splendid plate by our late friend Chris yeats on this forum 3 years ago after your own plate in the Ascofrance database a yeara ago . Chris gave then some explanations on this species different sites and the ''taming'' process of Canadian geese

Re : ascobolus
These were samples of barnacle geese dung kindly supplied by collegues in Scotland. Collected just after they had arrived from Greenland. I was hoping to find one of the recently described 4 spored species of Ascobolus.
I had found A brantophilus on wild goose dung from a local country house lakeside.
I will look out the plate by Chris (seriously missed)

Re : ascobolus
I answered a little too quickly; indeed it could be brantophilus as far as the ornamentation is concerned, but on the other hand the spores are a little small. Dissing also speaks of a browner shade for the apothecia and a dextrinoid reaction for the cells of the ectal excipulum.

Michel.
