MYCOSPHAERELLA ULMI . Leaf blotches and premature defoliation almost certainly caused by this fungus on stoolbeds of Ulmus procera .  Puzzling as leaves produced fruit bodies only after many weeks of incubation but these were apparently the phyllosticta and septogloeum imperfect states of Mycosphaerella . Location: Alice Holt , Hampshire , England .
