146 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



made during dry weather. The somewhat drab color the hy- 

 menium assumes in drying and its deep cracks are highly char- 

 acteristic of dried specimens. Colored conducting organs are 

 abundant in the hymenium and subhymenium and should 

 be demonstrated if other characters leave the determination 

 doubtful.
