Footwear blamed for 'rock snot' invasion of Md. streams
By Associated Press

Felt-soled fishing boots, of all things, are apparently the latest threat to local fish populations, prompting Maryland to ban the shoes in hopes of stopping an invasive form of algae -- appropriately dubbed "rock snot" for its resemblance to yellow-brown mucous -- from hurting pristine trout streams, the Associated Press reports.
Maryland's Department of Natural Resources plans to prohibit wading with felt soles starting March 21 after discovering that "rock snot," or didymo -- a type of algae that coats riverbeds in thick mats -- thrives in the shoes' damp fibers and hitches a ride from one body of water to another.
Rock snot has found its way across the U.S. and as of March 21, Maryland will become the first state to enforce a felt boot ban. It was found in 2008 in the Gunpowder Falls north of Baltimore. A western Maryland stream, the Savage River, also has tested positive for the organism but hasn't had a rock snot bloom. Similar bans will take effect in Vermont on April 1 and in Alaska in 2012.
