Something really wierd

I was looking at one of my gardens about 7 days ago and notice a yellow substance (looked like vomit) on some alyssum that was planted there. I took the hose and tried washing it off with the spray nozzle and the subsatnce started to foam a bit. Then about two days later the substance had turned brown so I had the hose in hand again so I sprayed it again and this time it looked like it was smoking and blew a dust cloud into the wind. Does anyone know what this was. It was really wierd and now it is just a crusty brown residue but the single alyssum plant is completely dead. Is this something that i should worry about? Let me know.

Dog vomit slime mold. Try a site search for previous discussions and photos.

There are spittle bugs that create foam on plants.

True, but their "evidence" is almost pure white, at least the varieties in the S.F. Bay Area. Do spit-bugs leave yellow crud on plants on the East Coast?

I think applestar has given a pretty reliable ID.
