Escovopsis germination assay. Germination of spores of three species of Escovopsis on plates with three culture media and in the presence of discs of potato dextrose agar with a blank control (no fungus, only agar), the basidiomycete Monoliniophthora perniciosa on agar or the host of Escovopsis, Leucoagaricus, on agar. Germination percentages are by records of growth following germination on Petri dish quadrants, such that recorded values were 0, 25, 50, 75 or 100%. Presented are means of these values from five such plates for each experimental situation, while error bars are standard errors of these means.
