Hello all

This Ascobolus was on Goose dung.

White apothecia turns dark brown on maturity, mostly 0.5mm across. Asci protruding more as it matures and eventually almost looks like A imersus.

There is bluing in Meltzers.

The spores have a smooth surface with few fissures 17-22 * 9-10

Paraphyses mostly cylindrical but one or two with swollen apex.

I have tried looking as Van Brummelen but not managed to come to any firm conclusion especially as some of the words used in the descriptions especially in the key to sections are unknown to me.

Re : Ascobolus
Hello Malcolm,

compare with Ascobolus brantophilus. Dissing described this species in 1989 (Four new coprophilous species of Ascobolus and Saccobolus from Greenland, Opera Bot. 100: 43-50). With strongly protruding asci and spores 21-23 x 10-11 with only few longitudinal often forked crackings this should be your species! It seems to be known from old goose dung in arctic areas only. Where did you find it?

I'll attach a pdf with the description and the drawings.

Stay healthy, Norbert

Re : Ascobolus
Hello Malcolm!

I discover your message and I also think of this species as you say Norbert; if this is confirmed it is a very nice find!

Re : Ascobolus
Norbert (and Michel)
Thanks for that. It was found by a lake in the North of England. There were lots of Canada goose, (Branta canadensis) and swans but there may have been others about.
The description by Dissing mentions a gelatinous sheath which I hadn't noticed originally but is definitely there so I think this is a very good fit for the A. brantophilus.
I will send a specimen to Chris Yeates and see if he can confirm. As the area is now in lockdown it is lucky that there are lots of fruitbodies available on the one sample I have.
Thanks once again.
