covered by the hymenium, in several species with a distinct toughish 

 root. Basidia narrow, elongated, divided at the end into two long 

 forks which bear one spore each on distinct sterigmata. Spores yellow 

 or orange, cnrved-elliptic like a sausage or one side curved, divided 

 into cells by cross walls before sprouting. Small conidia often pro- 

 duced by the sprouting spores and on the surface of the young fruiting 

 bodies. For development of basidia and other cytology see AYager 

 in The Naturalist 695 :3(U. 1914.
