A small Cleistothecia? 0.13 mm across x .08mm high was found growing on unknown dung (probably bird as it was on the top of a Leylandii hedge) along with many Podospora conica. It looks to have multispored asci (probably 16) with cylindrical spores 4.5-5.4 x 2.2-2.6.Can anyone help
Thanks

Re : Dung fungi?
Hallo Mal,
you should compare with Westerdykella nigra (=Preussia nigra).
At first with 8 spores, immediately separating and soon with 32 ascospore segments.
4-5,2 x 2,4-3 µm.
Regards, Norbert

Re : Dung fungi?
Hello Norbert
I don't have any detailed description of Westerdykella nigra but from what I can gather it is a close relative of Sporormiella. These also split into segments and have a spore septa. Looking more closely at my find the spores do not look to be grouped in the asci and I see no sign of the septa in fact I think I can see droplets at each end of the spores. I don't know if this would rule out the Westerdykella (Preussia) group.

Re : Dung fungi?
Hello Mal,
yes, the genus Westerdykella seems to be near to Sporormiella, Preussia.
Another option for the species you found could be W. cylindrica (Asci 17-25 x 9-10).
The asci of W. nigra should be larger (30-40 x 9-11).
We spoke about Westerdykella nigra / cylindrica / multispora in the german Pilzforum.eu some years ago.
At answer #6 you can find two pdf.
In the Doveri article there's a description of W. cylindrica (p. 209-212) and in the article by Ebead et al you can find a key (p. 197-198).
The discussion you will find here (sorry, in german):

Maybe this will help you a little bit more.

Norbert
Reading through those articles W cylindrica looks a perfect match.
Thanks for that.
