Disco on Pteridium aquilinum

Jakob Schneller, 19-07-2016 17:42

Dear collegues, I need help.

The fruitbody is very small about 0.1-0.2 mm. It shows a peculiar outer, dark excipilum with somewhat a netlike structure. The inner excipulum has more or less rectangular cells. Spores are unicellular and are about 6-7.5 um large. The asci about 30-35 um, with a blue tip with melzer. It was found in the Lower Engadin at about 1330 m a.s.l.

Thanks

Jakob Schneller
