THE THELEPHORACESE 453 



Corticium 1 act cum. Fr. 



This is a very small plant, resupinate, membranaceous, and it is so named 

 because of the milk-white color underneath. The hymenium is waxy when moist, 

 cracked when dry. 



Corticium oakesii. B. & C. 



The plant is small, Waxy-pliant, somewhat coriaceous, cup-shaped, then ex- 

 planate, confluent, marginate, externally white-tomentose. 



The hymenium is even, contiguous, becoming pallid. Spores elliptical, appen- 

 diculate. 



I found very fine specimens of this plant on the Iron-wood, Ostrya Virginica, 

 which grows on the high school lawn in Chillicothe. In rainy weather in Octobet 

 and November the bark would be white with the plant. It resembles a small 

 Peziza at first. 



Corticium incarnatum. Fr. 



Waxy when moist, becoming rigid when dry, confluent, aglutinate, radiating. 

 Hymenium red or flesh-color, covered with a delicate flesh-colored bloom. Some 

 fine specimens were found on dead chestnut trees in Poke Hollow. 



Corticium sambucum. Pk. 



Effused on elder bark, white, continuous when growing, when dry cracked 

 or flocculose and collapsing. It grows on the bark or the wood of the elder. 



Corticium cinercum. Fr. 



Waxy when moist, rigid when dry, agglutinate, lurid. The hymenium is 

 cinerous, with a verv delicate bloom. Common on sticks in the woods. 



Thelephora. Fr. 



The pileus is without a cuticle, consisting of interwoven fibres. Hymenium 

 ribbed, of a tough, fleshy substance, rather rigid, then collapsing and flocculent.
