Hello,
Found by Theo Westra, 13-06-2019 (The Netherlands) on deer dung (Dama dama).
Is this Hypocopra brefeldii?
Used "Keys to fungi on Dung"
(Page 38: Hypocopra)
Asci: 8-spored, IKI+
Spores with a germ-split, spore size: 24.3 x 12.7 µm
Greetings, Riet

Re : Hypocopra brefeldii?
Hello Riet,
indeed it looks good for Hyprocopra brefeldii. The ascospores should have a small basal apiculus (often collapsed and not easy to see, mostly when still young). You can compare with a nice portrait at Pilzforum.eu by B. Wergen.
A great article to this genus is Krug & Cain_New species of Hypocopra (Can.J.Bot. 52, 1974). Here is a link to my webspace, where you can download this.

By the way. I'm nearly sure, that the substrat is hare dung (because of its character and nature).
Greetings, Norbert

Re : Hypocopra brefeldii?
Hello Riet.
In my opinion, your fungus looks very similar to H. brefeldii; germinative slit shorter than the sporal length, rather equilateral spores, corresponding Melzer reaction, stroma with one or more perithecia. F. Doveri gives two-cell spores in his description, but it is often difficult to distinguish them clearly.
cordially.
Michel.
