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.
