Phaeosphaeria herpotrichoides, Red Moss

Once I got over the idea that the piece of herbaceous stem I had in my hand was Juncus I was able to track this down to Phaeosphaeria herpotrichoides. Should help identify its cohabiting smaller pyrenomycete too.

Tucked under the surface with ostiole exposed

Spores olivey-yellow en masse in the asci

Typical Leptosphaeria (s.l.) spore bulge

Curious - a stretched ascus?
