A very pretty little planl as its Bnowj white color shows again 



a background of Leaves or grass in open \\ Is. The buIi utr 



acter of the margin of the cap appears as the plant loses d 

 ture; sometimes a Blight papilla is present. The gills are quite 

 distanl a1 times, with shorter gills alternating. Under the mi< 

 xn>[>r the stem is Been to be covered with verj Bhoii hair-like '■'•lis 

 which under a hand-lens appear only as a slight pruinosity. The 

 trama of the .uills consists of interwoven hyphae. Our plants wi 

 not attached bj fioccose hairs as shown in Cooke's figures, but 

 were almosl free of them.
