different locality in 1896, and Demetrio found it in Cole County, 

 Missouri, September, 1898, growing in a decayed spot on a living 

 red cedar trunk. 



The nearest American congener of this species is probably A. 

 quercinus, from which it may be easily distinguished by its milk- 

 white context. It is also known only on red cedar, while 

 A. quercinus occurs on the wood of deciduous trees.

This remarkable species has a literary history in keeping with 

 its wonderful variation in nature. Bolton appears to have the 

 credit of noticing it first, and, fortunately, his description and 

 figures are excellent. He speaks of it as growing on stumps and 

 the dead roots of trees at Fixby-Hall, the type locality, and other

 zonatus subfuscus, carne ferrugineo-pallide, tubis cinereis poris 

 multiformis." 



Persoon made use of Bolton's name, but does not seem to be
