pyreno on Bolboschoenus maritimus
Jac Gelderblom, 29-08-2018 17:05
Hello

On old stems of Bolboschoenus (Scirpus) maritimus I found some tiny pyrenomycetes (diameter ca 0,2 mm). The spores measured 32-40 x 7-8 micron, they were brown en with 4 septa. The asci measured ca 120 x 14 micron and were bitunicate. At first I thougt it might be a Leptosphaeria or Phaeosphaeria but my doubt is very great.

Does anyone have an idea?

Best regards
