This species occurs on living trees, logs and dead limbs of 

 conifers in forests of the Rocky Mountain region and from British 

 Columbia to Arizona in the Pacific states. The fructifications 

 are somewhat coriaceous, loosely attached to the substratum, and 

 vinaceous in color. The spores in most specimens are colorless, 

 even, 6-10 X 4-7 y., not copious fully mature and colored in 

 only one of the specimens received during 14 years.
