This beautiful purple, white-bordered species was originally 

 described and poorly figured by Persoon from specimens col- 

 lected by Chaillet on the trunks of a conifer. Standing as it 

 does on the border line between Merulius and Poria, it has re- 

 ceived a number of names, both in this country and in Europe. 

 Most of the herbarium specimens in the Poria sheets are called 

 either P. violacea or P. incarnata by Fries, Karsten, Plowright, 

 Ellis, and others. Burt includes it in Merulius, — as did Persoon, 

 — and I have no desire to alter this arrangement. The hyme- 

 nium is often strikingly merulioid when young. The spores are 

 allantoid, hyaline, 3.5-4.5x0.5-1.5^. It occurs on dead wood 

 and bark of pine, spruce, fir, Cupressus thyoides, Thuya occi- 

 dentalism and other conifers. One specimen from Karsten is said 

 to have been collected on a deciduous trunk.
