Podospora on goose dung
Chris Yeates, 25-05-2021 13:24
Chris Yeates
A Podospora has appeared on the same collection of goose dung which produced Ascobolus brantophilus - http://www.ascofrance.com/search_forum/68789

Perithecia are mostly sunken in the dung. The asci have 128 spores, with the spores measuring 19.8-22.3 x 13-13.5µm. The immature spores are spoon-shaped; the mature spores have a distinctly eccentric apical appendage (best seen in the asci, when liberated this appendage is soon more difficult to see); there is a basal appendage which is even more fugacious.

This keys out to the P. setosa / P. tarvisina area, but there is a major problem - the perithecia totally lack the setae one would expect in those species - see accompanying images which I shall post in two batches.

Any suggestions would be welcome.

Cordialement, Chris

Re : Podospora on goose dung
Hello Chris.

You could perhaps compare with P.ampullacea which has no hairs and which can sometimes have asci with 128 spores.


regards.


Michel.

Re : Podospora on goose dung
Merci Michel

I had wondered about P. ampullacea, but was unsure as that is supposed to have a channelled apical appendage, and these don't seem to have that. I'll have a look at another perithecium, paying special attention to that feature.

Amitiés, Chris
