Coniochaeta tetraspora?
hannie wijers, 27-06-2013 20:45
I wonder if this could be a Coniochaeta tetraspora. I found it on horsedung. Four spores in an asco, sometimes rthere were five of them. The measure of the spores are 14- 17x 10-12 µm

The hairs are   25-99 µm, asci 115,5-140 µm

I didn't have any reaction with Melzer.

Does anyone have an idea?   

Best wishes

Hannie

Hi

if there is a problem, you also can send the photos to me, I had found C. tetraspora already and you can compare with my website too.

Hello Björn,


In a monograph from Mahoney & LaFavre (Mycologia Vol. 73 1981) it is stated that C. Tetraspora is only isolated from soil and not from dung.

In the following article http://www.stanford.edu/group/neurospora/pdfs/Raju2000.pdf  it is stated that immature asci of Coniochaeta tetraspora originally contain eight uninucleate ascospores. Two ascospore pairs in each ascus survive and mature, and two die and degenerate.

Did you find any immature asci containing eight spores?
