 124 ANNALS OF THE MISSOURI BOTANICAL GARDEN 



Fructifications 1-4 mm. in diameter. 



On bark of fallen limbs of Pinus resinosa. Maine and New 

 Hampshire. August. Rare. 



The fructifications are so near the color of the bark of the 

 dead pine limbs upon which they grow that they are likely to be 

 overlooked, or, if collected, roughly classed among the Dis- 

 comycetes on account of their resemblance to these fungi in 

 aspect. The occurrence on pine bark, small, shield-shaped 

 fructifications Benzo-brown in color, and showing in section 

 both cystidia and gloeocystidia are a combination of characters 

 which should not fail to identify this species.
