Anybody seen this before? Bluish, somewhat globular fungus along the edge
of the blades, extending from the middle to the top. Touching it releases
a
fine black powder. Just a few spots affected so far. Can't google up
anything on this.
It is a species of Entoloma fungi. They don't harm anybody, and you should
not use fungicides.
