Podospora dakotensis?
M. M. Gotink, 24-05-2010 23:34
I found this one today on hare dung which I keep in a moist container (since March 27th).

Fruiting body 850 x 450 µm, without hairs.
Asci probably 32-spored (difficult to count, at least close to that), 170-210 x 30-35 µm.
Spores 2 celled, main brown cell 20-23 x 11-13 µm, hyaline pedicell about 6-7 x 2 µm, appendages variable, rather long.

There are not many possibilities with 32-spored asci as far as I can see; P. pleiospora has bigger spores, and there is a P. dakotensis which spore size perfectly fits my finding.

Are there any other possibilities, or is this P. dakotensis for sure?

Hello.

P.pleiospora has also appendices different. It is certainly P.dakotensis, but could You can check for the presence of hair at the base of the neck.
Have a nice day.

Hi Martin,
It is almost certainly no Podospora. It is a species of the genus Schizothecium. ;-) Even the shape of the fruiting body shows me this. On the neck should be no hair, but Squamofolien be present. These look something like this like a scorpion's tail. Even if I look at your photos no appendage, I think it is S. dokotense. The counting of the spores is of course best with immature asci.

Best regards Peter

Re:Podospora dakotensis?
Hi Michel, Peter,

I'm sure I've not seen real hairs at the base of the neck, but I've seen some agglutinated hairs (Squamofolien), see attachment, unfortunately the picture is not so clear.
According to Indexfungorum Podospora dakotensis is the current name, Schizothecium dakotense is a synonym. The appendages were hard to see, I've got a picture of them, but again the picture is not so clear.
I can try to make better pictures later on if it is needed, or is it Podospora dakotensis/Schizothecium dakotense for sure already?

Re:Podospora dakotensis?
Yes, that's the species Martin.

These are precisely the Squamufolien. In this species, they are not very large. The Index Fungorum is not correct. Also Doverie has now accepted the genus. We Lundqvist, Heine and I have said this a long time and Cai, Jeewon & Hyde have the evidence with the help of DNA. When I read through the work, probably the genus Podospora will have to be divided.

Re:Podospora dakotensis?
So this is Schizothecium dakotense for sure? That means a new species for the Netherlands again... This is not a very common species in Europe according to 'Coprophilous fungi in New Zealand I - Podospora species with swollen agglutinated perithecial hairs'?

Re:Podospora dakotensis?
If no one has collected the mushrooms in front of you, you will make many new discoveries.
It is a beautiful world, particularly under the microscope.
Schizothecium dakotense is not often, but not rare.

Re:Podospora dakotensis?
A beautiful but often a difficult world too, at the moment I don't even try to determine most of the 8-spored Podospora/Schizothecium because I find them very difficult.
Thanks for your help Peter and Michel!
