What kind of fungus is this?
October 21, 2012 8:58 PM   Subscribe

Fungusfilter. My parents cut down a tree several years ago and had the stump ground up. About 2 years ago, this red fungus started growing up through the grass. It starts off as a beige foam and then solidifies and turns into a rubbery red color. It grows around the grass before solidifying. I thought it might be reishi but that just doesn't seem right. Here is an image. Thanks all.

Schweinitzii root and butt rot?

They're a type of shelf fungus (bracket fungus) that probably have their origin in the stump, like these.

Schweinitzii is fuzzy... and then when old it gets brittle and crumbly. It isn't really hard and rubbery, and it doesn't ever get shiny, in my experience, and I see a lot of it around where I live.

Probably Ganoderma tsugae

If you want a bunch of images, google "varnish shelf fungus"

What kind of tree was it? Was the tree sick when it was cut? What does the underside look like (aka "pore color")? Polypores can be really hard to key out.

Phaeolus schweinitzii is a root pathogen on conifers. Ganoderma tsugae tends to grow on hemlocks, but it should be hard, not rubbery, and I haven't seen Ganodermas layered on top of each other like that.

It was a locust tree and it was healthy as far as I know. I'll have to take a look at the underside and I'll let you know.

I'm pretty sure its Phaeolus schweinitzii. After looking at images and descriptions, I'm pretty sure that's it.
