What the hell is this?

[penumbra]

Reminds me more of cat vomit

Does it smell anything like tuna?

Does it smell anything like tuna?

Probably

 

[NOZZLE HEAD]

Tons of different types of “slime mold” out there. As far as I know they are not plant pathogens and usually transient when growing on live plants.

I’d physically remove it, but it should not infect the tree.

Not telling what you should do, but it would make a great excuse to try a new piece of kit..

 

[StarGazer]

Fuligo Septica, harmless.

Crazy! Living in Florida the only slime mold I’ve “seen” has been the shelf fungi that crawl around and eventually build shelves on dead wood to fruit. I’ve never seen the dog vomit in any color!
