yellowish powderly appearance. In germination, each daughter spore 

 produced a slender 4-celled promycelium from its tip, or rarely from 

 the base, and bore a spherical sporidium of 4-6// in diameter on a 

 short Bterigma. In this case, the daughter spores did not separate 

 from each other being closely united together. The sporidia soon 

 germinated in water producing slender germ tubes. The secondary 

 sporidia were often observed at the tips of the short hyphae.
