Dog Vomit Slime Mold Fuligo septica

 That's what I have in my flowers/bushes in front of our condo.  I took a photo and posted it on Facebook. Someone identified it. It's bright yellow early in the morning. It even has a Latin name, and was identified and named in the 1700s.

Folklore

In Scandinavian folklore, Fuligo septica is identified as the vomit of troll cats.[18]

In Finland, F. septica was believed to be used by witches to spoil their neighbors' milk. This gives it the name paranvoi, meaning "butter of the familiar spirit".[8][19] In Dutch, "heksenboter" refers to "witches' butter". In Latvian, the slime mold (amongst other slime molds) is called "ragansviests" as "witches' butter" or "raganu spļāviens" as "witches' spit" but it is unclear about the origins of these names.

Human pathogenicity

The species is known to trigger episodes of asthma and allergic rhinitis in susceptible people. [20][21]
