Dear Eduardo

I remember a big Ascobolus that I once found on horse dung in my garden. It was identified as A. scatigenus, but I never saw it again.

Here is the photo, and one from Panama by M. Piepenbring (left one) which I think might be the same species.

But it can well be that there exist several similar such species.

Re : Coprophilous Pezizaceae (2)

I remember that Meike said about the Panama fungus that the dark hymenia shoot their spores simultaneously upon touch or wind, thereby getting whitish within a blink of an eye! So the pale ones must not be immature.

Real time.

Re : Coprophilous Pezizaceae (2)

It may well be Ascobolus scatigenus. There are hardly any other Ascoboli reaching that size. I've seen it quite frequently on horse dung in Australia. It seems to prefer the tropics or at least warmer regions. @ Zotto: I don't know of any other German find. What a garden!

Regards, Till

Re : Coprophilous Pezizaceae (2)

Hi Till

It was dung from our neighbors, who keep horses. Possibly there was some inoculum introduced from the tropics, otherwise I cannot explain. Sometimes I think I have also introduced some fungi into my garden through specimens sent to me. But this Ascobolus was long before Guy made his trips to Australia...
