This polypore is growing on the base of a bay tree, not near any water. It feels clammy and damp to the touch, but quite solid. It’s 11cm across at it’s widest point and I first observed it on September 6, 2006. Although it hasn’t formed a cap in two months, it did, indeed, stain dark brown when I scraped it with my fingernail.
May 5, 2007: Image 4636. This never grew a cap and languished all year. Recently I noticed that it was fruiting again on top of the original structure which can be seen, in the third photo, underneath the new one.
May 17, 2007: Image 4825. I happened to go by and noticed that the brown is spreading pretty rapidly on this. It measures 14 cm across the widest area.
June 16, 2007: Image 5292. It’s now 15 cm across.
July 12, 2007: Images 5522, 5523. Not much bigger at 15.5 cm but there’s new growth underneath and more brown on top.The white areas remain fresh looking and feeling.
August 27, 2007: Image 6093. 20 cm wide.

I don’t think I’ve ever seen a time series of the growth of a conk. It would be great to keep seeing regular (monthly?) pictures of this. It definitely looks more like a conk now with the brown center showing.
The polypore on Bay is usually Ganoderma applanatum. You can identify it by scratching the white area and seeing if it instantly turns deep brown or waiting a week until the polypore gets larger and seeing the color and texture of the cap.
If you scratch the white area with your fingernail does it change color?
