That's no joke. Lyophyllum decastes is commonly known as the fried chicken mushroom, and the answer is Yes, it does taste a little like fried chicken—at least to me it does, although Wildman Steve Brill begs to differ. It's greasy like fried chicken and a little bit chewy. The stems are fibrous, so you're better off using just the caps. I floured mine and pan-fried in butter. Pretty simple.
Fried chicken mushrooms grow in clumps (sometimes huge clumps of several pounds or more) in disturbed areas. They're common along roadsides, but beware: these same roadsides are often sprayed with herbicides and other nasty chemicals which get biomagnified by the mushroom; make sure you pick these in safe areas.
