I’m not sure what this is growing on. It’s in one of those wells surrounding trees on a city street that I walk by several times a week. The tree is a non-native hardwood but the fungus is growing at the edges of the concrete, rather than at the base of the tree. There are two individuals. The larger fungus is 24 cm across. I’d guess that it’s been there more than one season and I just never noticed before it began to put forth some new growth.
8/3/07: I’ve added some pictures of the tree. Turns out they’re common street trees here in Santa Rosa. I believe it’s Celtis occidentalis aka Common Hackberry. There’s also a picture of the area with the G. applanatum outlined. This particular tree has a deep root system which makes me think it’s not the host. It’s hard to tell if the live oak seedlings are from underground roots or just seedlings that have sprouted.

Ganoderma applanatum ????

IM very familar with G. appalanatuum The G.applanatum in West Virginia has very different Characteristic than these images. Out of the 100’s that i have found the fruiting body has always been some what uniformed in a half dish fashion. There are small striations on the caps no larger than 2 cm. There are smooth bums and ridges on the cap, They all have been tan with dark brown striations with no reddish or reddish brown colors such as this image.I have seen these as large as turkey platters and weighing 30 lb. There called the Artist Conk I collect them for that pupose. This looks more like one of the resinous polypores. more like G. lucidum G. Tsugae but most likely Ganoderma resinaceum

Could you get a picture of the tree so maybe we can get an id on that? Also it looks like there are some live oak shoots growing with it. Maybe there was a live oak there that someone took out and now the Ganoderma is growing out of the remains of the trunk and roots.
