Leptosphaeria eustoma?
Gernot Friebes,
12-08-2010 12:35
a friend of mine sent me two pyrenos which are not definitively determined. The first one is a Leptosphaeria (eustoma?) on Daucus carrota which grew subepidermal. I was not able to find any asci anymore but according to the finder they are 140-160 x 14-15 µm. The spores are 22,5-25 x 7-8(10) µm and always three-septate if mature. The peridium is quite thin. The ostile apparently doesn't consist of periphyses.
Best wishes and many thanks,
Gernot

Hi Gernot,
Leptosphaeria libanotis is known to attack Daucus carrota (and other Umbelliferae). Spores are very similar to yours.
