No specimen available

Notes:
This was an interesting observation. On June 7th I came across half a dozen polypores fruiting on the stump and buried roots of a hardwood tree that had been cut down about 5-6 years ago in a residential landscape.They were obviously in a very immature stage and I didn’t recognize the species at that time. I revisited the site and photographed the specimens periodically as they developed. They grew very slowly, but by July 1st I was able to photograph the pores and had a pretty good idea what the specimens were. This morning I took the final photograph and decided it was time to post this observation. These specimens have pores that are initially round and slightly angular. As they develop they become very angular, eventually taking on a labyrinth-like appearance. Mature pores measure 2-3 mm. depending on their shape. No part of the specimen bruises black even with vigorous rubbing and squeezing. Some clear, watery liquid could be squeezed from individual caps. Cap surface slightly velvety. Context very tough to slice. Following the thumbnail photo is a series of images (with dates) documenting the development of this specimen over a month’s period of time, plus additional photos of various features.
