Seedfork said:White, slimy masses of microscopic spores (conidia) produced in diseased tissue are splashed by water or wind-blown rain from fallen leaves and cane lesions to the opening leaves in the spring......."

"Conidia lose viability rapidly, few surviving more than one month. Overwintering is by saprophytic mycelium in cast foliage or infected stem tissues"

Not sure what they "meant", but I know what they say. The first sentence states that conidia over winters and transfers to the new leaves in the spring, the second sentence says conidia lose viability rapidly few surviving more than one month. So either one or the other is incorrect it looks like to me. I will leave the meaning up to each reader to decide.

I don't see where in the first sentence it says that conidia overwinter?? It says they are splashed to new leaves in spring but doesn't say they've been there all winter. The article you're quoting is this:

If you read further down that same article, it says "Following defoliation in the autumn, the hyphae go deeper into the dead leaf tissue and form black specks (pycnidia) under the old acervuli. The pycnidia rupture in the spring, exposing the white slimy masses of conidia and completing the disease cycle.."
