 crowded, branclicil, white, then stiaw-color; milk acrid, white. 



In woods. PiK'us 3 t> in. broad, stii)e 1^ 3 in. long. Very similar 

 to the next species, but the sti[)e longer, tlie pileus thinner and the 

 lamellre not arcuate. 



-7. L. piPEiiATCs, Scop. — White. Pileus compact, umbilicate, then
