 200 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



On roots of living apple and blackberry plants, on the ground, 

 and broadly effused on rotting logs of frondose and coniferous 

 species. Canada to Texas and westward to the Pacific coast, 

 in West Indies and in Japan. Throughout the year. Common. 



C. galactinum resembles C. portentosum in aspect but has a 

 more erect hyphal structure and is usually not at all stratose and 

 with substance not colored. Both species have a hymenial sur- 

 face composed of fine, curved hyphal branches, but the spores 

 of C. galactinum are smaller and ellipsoid and those of C. por- 

 tentosum spherical. The mycelium of C. galactinum was col- 

 lected as a parasitic root rot on the roots of young apple trees 

 and blackberry bushes and developed mature fructifications. 

 The collector's data on the type specimen of this species is "In 

 radicibus ad latera fossarum."
