Hi to all:This asco seems to form amphigenous stromata (or is only a blackish subiculum?) on Pistacia terebinthus old leaves in Extremadura (SW of Spain). The pseudothecia are black, superficial, sphaerical, up to 250 micr. of diameter, and they seem to be glabrous. The stromata (or the subicular tissue ?) forms superficial and circular patches up to 3 mm that include many pseudothecia
