Hardware TonyMinute cluster of very small 0.1mm ascomata on Urtica dioica (Nettle) shows isolated staining of stem blue and has longitudinal 3-4 grooved/4-guttulate ascospores as found in L. viridarium, except has vastly smaller spores and structure. Attach details and micros. Appreciate any proposals.
With thanks
