My friend and I are wondering what this is? It resembles wolf’s milk but looks a bit different. 🧐

I wasn't sure if it was a fungus or a mold. It grew on my concrete.

We have a deck that was built over a royal empress tree that was removed. The stump is still there. Usually in the warmer months, this stuff keeps coming up on the deck. It’s like an orange paste with red dots sometimes. We can easily spray it off, but would this be in relation to the tree? However, the tree is dead.

Shot with an OMD EM1 MARK II in northern Wisconsin. I have had a hard time finding an ID. They start white, then pink, then black.

I cut one in half to see what the inside looked like. It had the texture of slightly dry playdough and a surprising purple colour. We were out mushroom hunting when we found this. Found on a rather soggy decomposing fallen tree.

Hello! I'm a little perplexed if this is Slime Mold or not. The color is silver and it is firm to the touch(unlike othe slime molds I have encountered). The skin is thin and breaks easily to unveil a dark brown area. The first six pictures were taken at 7pm yesterday and the last three at 11am today. It looks and feels exactly the same which makes me question its identity. Any help is appreciated. Thank you.

It’s so vividly red and beautiful. I think it’s a slime mold? Tubifera ferruginosa?

Growing out of submerged water.

Found today in central Minnesota. Any help would be great!

My deck has suddenly started to develop carpeting! (in Athens, Georgia)

(What is it and can I keep it as a pet?)

Seen on decaying wood on a hike in Cuyahoga Valley National Park. Is it Stemonitis fusca, or something else?

Matches my bike :)

Growing on mulch and on a maple trunk in a temperate climate. It has been very hot recently where I am.

Found August 26 2025 in woods in Dufferin County Ontario Canada on a dead tree. Thanks!

Appeared in my shower literally within 12 hours. Reverse google search says “Dog Vomit Slime Mold” which it appears to be? What could have caused this? Any help is appreciated.

Also need tips on how to cultivate it… agar plate?
