Hey guys, New to the forum, and mushrooms altogether for that matter. Attached are some (poor) photos of mushrooms I shot with my cell phone when I was out birding. All photos taken just north of Baltimore, Maryland, USA in deciduous forest (many Tulip-trees). 1) Had dark gills underneath, thinly lined white; stems were all-white, no "bracelets." 2) Brown, bendy, rotten wood-like formation on the ground. Groundwart? 3 and 4) All-white, fan-like fungi on rotting logs. Topside with ridges (see photo3), underside with very closely packed gills, all-white.
