Remarks
"This thing here in Texas is surely an exotic; it's even a pest if you like polypore. The first examples I came across are from Travis Co. (Austin area) dated 2003. I have since found it at other places; it is always abnormally abundant and thoroughly and unnaturally pulverizes its host fungus. At a 'virgin timber' location in the deep forest of eastern Texas, it is now very abundant on every piece of common white polypore I find. 20 years ago, when I last surveyed beetles at this site, this species was not present." (E.G. Riley, pers. comm. to MAQ, 2009)
