this asco on twigs, Asci slightly J+ and operculate.
spores 14.5 -16.4 long,  looks a little warthy within the ascus but it appears to be little drops  of oil, further the spores contain 2 big droplets of oil.
who has a suggestion ?

Peter

Hello Peter

see http://website.nbm-mnb.ca/mycologywebpages/NaturalHistoryOfFungi/DiscomycetesDiscussion.html
