Anyone Know What This Is Growing On My Astroturf Lawn

Question

Over the winter, I have noticed this (see picture) growing on my Astroturf lawn. It is slimy in texture and looks like a fungus. Any ideas on how to get rid of it.

Answer 1

This is a type of cyanobterium. This used to be known as an algae, but has since been reclassified.

The most effective way to deal with this is to let the area dry out. The moisture will invite the bacteria back. You can also treat with copper sulfate, which will rid the area of the slime.
