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.
