1919^ The Hydnums of Xoktii Caeolixa 177 



a complex manner like the coral Hydnum, but forms a heavy, solid 

 mass that is covered with long, fleshy, parallel, pendant spines. It 

 projects laterally from a narrowed point of attachment and requires 

 several weeks to attain its full size, which is often several pounds in 

 weight. The color is creamy-white or yellowish and it turns brown 

 on drying. The spores are smooth or perhaps very minutely rough, 

 spherical to subelliptic, 4.8 x 5.5/^, or when spherical about 5/x in 

 diameter. 



This species is said to be very variable, but in Chapel Hill it is 



unusually constant in its appearance. Only one of our collections 



(1^0. 295) varied in shape towards the form called ilf. caput-ursi. It 



is easily distinguished from il/. flagellum both in form and in the 



larger spores. Edible.
