Asco on Grouse dung
Malcolm Greaves, 16-12-2016 16:33
Malcolm  GreavesHaving found Ascobolus carletonii on the grouse dung a lot of Sporormiella australis developed but I then came across a third species. A small black almost spherical Perithecia with a short neck sparsely surrounded by short dark pointed hairs. The spores were either narrowly ellipsoid with a germ slit or more rounded without the slit. I think it could be a Coniochaeta but although it is close to C saccardoi it does not seem a perfect fit for any species in Ellis and Ellis. The spores are 10-11.8 x 4.9-5.3 or 6.2-7.1
Thanks

Hi Malcolm, have you Ann Bell's Coprophilous Ascomycetes of Australia book?  Best - Jason

Good evening Malcolm.

Still a difficult genre where species are delicate to separate. On your picture of the spores one sees nevertheless that the latter are rather wide. One must be wary of the three dimensions and make numerous preparations and measure many spores. Try to see if the germ slit goes around the spore. You can also measure the asci. I do not know C.saccardoi, but Checa gives longer spore measurements.
Your mushroom could be within the size range of C.discospora.

Thanks Jason yes I have a copy of that. Thanks also Michel I was hoping for more specimens to grow to be able to give more information but nothing has shown yet. I will get back if/when I have more information.

Re : Asco on Grouse dung
Hi Malcolm, I forgot to mention another helpful reference book is Nils Lundqvist, Nordic Sordariaceae (1972). I wonder if you have access to this beautifully illustrated book? Best - Jason

Re : Asco on Grouse dung
I regularly find species of this kind and it often happens that I can not determine with precision. I can send you the Checa paper if you do not have it. Indeed as Jason says you can also consult the book of N.Lundqvist as well as that of F.Doveri in Asco.Org 08 01.

Michel.

Re : Asco on Grouse dung
I have finally found a couple of Perithecia in amongst the hundreds of Sporormiella.
Very similar to the first find with spores (10.3)11.21(12.25) x (5.2)5.68(6.5) x (6.44)7.27(7.61) 30 spores measured.
It does not fit perfectly with any in Ellis and Ellis, Keys to Dung Fungi, Dung Fungi of New Zealand or The Genus Conichaeta Checa (thanks Michel). The best fit seems to be C discospora currently synonomised with C ligniarea in the UK.
Thanks for all your help.
