Identification: Slime mold: grows within 24 hours at 40-60% humidity or stagnant tap water

Hi I've been having a peculiar mold problem and after days of research online I can't find another sample that looks like it.

This one showed up in my dehumidifier after 12 hours of running


This one showed up 24 hours after taking a shower


This grew in a glass of tap water I left out for 2 days to see what would happen.


Color: Yellow/green with black specks

Texture: Slimy almost feels like mucus

Area: San Jose, California near this areaGoogle Maps

Other info:
I've also reached out to my neighbors as well and they say they have had the same problem starting from Nov 2017 but never before.

 

I don't think that slime molds grow in water. This looks more like a mat of various bacteria and/or fungi that grows in stagnant water containing some nutrients. The species would be impossible to identify without DNA analysis.

 

Hi Jann, I agree with Vitog - not a slime mold (myxomycete), and there are various possible organism combinations. Perhaps reaching out to either your local government or to a local university, to report these recent area changes and to see if they are already aware of this?
