Feeding and other inter-species relationships

Associated with Lactuca sativa:

Photos (dead) dead is decayed by effuse colony of Stemphylium dematiaceous anamorph Pleospora allii - an ascomycete (Pleosporales: Pleosporaceae) Ellis, M.B. & J.P., 1997
Photos (live) live is parasitised by Golovinomyces cichoracearum - a powdery mildew (Erysiphales: Erysiphaceae) UK/Ireland Ing, B., 1990
Ellis, M.B. & J.P., 1997
Photos may be infected and damaged by Botrytis cinerea - a dematiaceous anamorphic fungus (Helotiales: Sclerotiniaceae) Ellis, M.B. & J.P., 1997 [plants often collapse completely]
capitulum capitulum may contain larva Trupanea amoena - a gall fly (Diptera: Tephritidae) Foreign Questionable White, I.M., 1988

leaf (live) live leaf is parasitised by aecium Puccinia opizii - Lettuce Rust (Uredinales: Pucciniaceae) Major Ellis, M.B. & J.P., 1997
leaf (live) live leaf has leaves shot holed by acervulus of Marssonina coelomycetous anamorph Microdochium panattonianum - a fungus (Xylariales: Hyponectriaceae) Ellis, M.B. & J.P., 1997 [causes pale brown spots with dark margins. Causes "Ring Spot" disease of Lettuce.]
leaf (live) live leaf is spotted by mostly epiphyllous pycnidium of Septoria coelomycetous anamorph Septoria lactucae - a leaf-spot fungus (Mycosphaerellales: Mycosphaerellaceae) Ellis, M.B. & J.P., 1997 [causes brown or greyish spots, sometimes with yellow haloes.]
leaf (live) live leaf is spotted by pseudothecium Pleospora herbarum - an ascomycete (Pleosporales: Pleosporaceae) Ellis, M.B. & J.P., 1997
leaf (live, mainly outer) live, mainly outer leaf is spotted by mostly hypophyllous colony Bremia lactucae - a downy mildew (Peronosporales: Peronosporaceae) Ellis, M.B. & J.P., 1997 [chiefly when grown under glass or overcrowded. Causes yellowish or very pale green patches.]
plant (rotting) rotting plant is decayed by sclerotium Sclerotinia minor - an ascomycete fungus (Helotiales: Sclerotiniaceae) Major Ellis, M.B. & J.P., 1997
plant (rotting) rotting plant is decayed by sclerotioid, stalked apothecium Sclerotinia minor - an ascomycete fungus (Helotiales: Sclerotiniaceae) Minor Ellis, M.B. & J.P., 1997
