Podospora curvicolla
Joop van der Lee, 20-01-2014 22:20
Joop van der LeeFound on dung from calfs of Scottisch highlanders, their droppings looked like flat pellets 2 cm in diameter and 1.5 cm thick.
I found 3 fruitbodies with different necks as fas as hairs are concerned.
One without hair, one with small stiff hairs and one with agglutinated hairs.
Hairs: stiff; single or agglutinated 4-5 um wide; septated; thick walled 0.8-1.1 um; round top; bulbous base.
Asci: Only young asci measured, ripe ones were busted 274-306x65-74 um; 512 spores.
Spores: 17.5-19x11-12.5 um pedicel 12x4 um; both upper cauda and lower cauda excist, only visible with young spores.

Re : Podospora granulostriata?
Hello Joop,
may be P. curvicolla, it's my supposition.
Greetings Peter.

Re : Podospora granulostriata?

Hello Peter,


 


P. Curvicolla does not have asci with 512 spores and pedicel is smaller accortding to Doveri. But I can look for fruitbodies which hold asci with ripe spores so I can measure the ascus and count the number of spores again.

Re : Podospora granulostriata?
Hello Joop,
if the number of spores are right ? I can not see the conspicuous caudae and the size of spores are in my opinion a little to small for P. granul. But I must say too, that I never seen P. g., P. c. is in our distrikt a very common species on several kinds of dung, the most on dung of Lepus.
Greetings Peter.

Re : Podospora granulostriata?
Hello Joop,

I agree with Peter.
This should be Podospora curvicolla.
Podospora granulostriata, which I know well from over 20 findings, has much larger spores and asci, of course. Mostly finds on dung of deer and roedeer, never on cow!
Own measurements: 22-25 x 12-15 µm.
And Podospora setosa with sporesize like you say, has asci with only 128 spores.

Re : Podospora granulostriata?

Vielen dank Peter und Norbert.
I have been reading the work of Lundqvist in which he placed questionmarks about the number of spores per ascus for P. curvicolla. Yesterday I counted 512 did either of you count a different number?
And do you have any idea why the neck can be so different in having hairs?

Re : Podospora granulostriata?
Hello Joop,
please excuse, that I answer to your question so lately. Now and again I also find perithecies which are hardly grown hairs in the neck, but I cannot explain this condition. However, there is a Podospora-kind with hairless neck, but with more than 1000 spores, P. millespora (Alf. Schmidt) Cain in Can. J. Bot. 40 (1962).

Greetings Peter.
