Setose ascomata on Trifolium arvense
Gernot Friebes, 01-01-2013 16:51
Hi,

a friend sent me this tiny ascomycete growing on Trifolium arvense. It bears some resemblance to Capronia but differs in ascospores with inconspicuous appendages and present hamathecium. We have no idea where to put this fungus so we'd be happy for any help.

I wish all AscoFrance members the best for 2013!

Best wishes,
Gernot

Re : Setose ascomata on Trifolium arvense
¿Podría ser Capronia?

Saludos.
Salvador.

Perdón, no había leido bién.

Re : Setose ascomata on Trifolium arvense
I would recommend to check literature on Trichometasphaeria and Keissleriella; the fungus might even be buried somewhere under Leptosphaeria or Metasphaeria.
Cheers,
Walter

Re : Setose ascomata on Trifolium arvense
Thank you Salvador and Walter! I will compare this fungus to the genera Walter suggested, hoping to find some matching taxa.

Best wishes,
Gernot

Re : Setose ascomata on Trifolium arvense
Yes Gernot, not so far away from culmifeda.
But on my personal culmifeda, the spores were less wide, and more constricted at primary septum, and on grass (A. canina).

Re : Setose ascomata on Trifolium arvense
alternatively, given the minute ascomata and occurrence on inflorescences, the fungus may have venturiaceous affinities or belong to the Pseudoperisporiaceae, e.g. to Nematostoma. The latter genus is e.g. known from Cirsium and Artemisia, but not Trifolium, as far as I know. Also, T. arvense is not a common species! One question in this respect is whether the fungus already occurs on living tissue.
Best regards,
Walter
