fescue sprouting lavender buds

Asked July 8, 2016, 12:31 PM EDT

My well-established tall fescue lawn has recently developed patches of grass where the blades are covered with tiny lavender bud-looking things. When I wipe a blade between my fingers, it leaves my fingers looking as though they are coated with soot. Is this some kind of fungus? Is there some remedy I should apply?

There are several fungi that can cause mycelia to grow on the blades of grass. Some examples are slime mold https://extension.umd.edu/hgic/slime-mold-lawns and red thread https://extension.umd.edu/hgic/red-thread-lawns. Pythium also can have mycelial growth on grass blades. http://www.apsnet.org/edcenter/intropp/lessons/fungi/Oomycetes/Pages/PythiumBlight.aspx You could put mycelium on grass blades into Google Image to see if you can match up what you have. When we think of lavender buds, we think of flower buds. If you can send a photo we might be better able to answer your question. vw

Thank you very much. It looks very much like the photo at https://extension.umd.edu/hgic/slime-mold-lawns, so I am going with that -- especially since it says I don't need to do anything drastic to remedy it. Thanks again, and I'm sorry I didn't send photos. I'm not very good at that -- you know, old and technically inept.
