Dark violet mold, hairy too!?

I just killed a spot of mold in my basement and was wondering what kind it is and how serious.



Specs:

1954 home

basement finished approx 1970's or 1980's

drywall entire wall

bottom half is that 1/8" "decorative" wood paneling

bottom 4" is that rubber flat trim.



Mold was growing between tiled floor and trim. In the bottom crack area.



It was about 2.5" long and looked like violet/black grass. When I sprayed it with 409 a smoke/powder erupted off of it, 3 times/3 sprays.



Took a lot of paper towels. It's also looked like one of those really hairy catapillars that are black with spikes on them. Please inform me of this monster that I killed, hopefully.

The fungus you saw is the fruiting body or flower of the little bugger. The dust you saw were spores or the seeds of the critter, millions and millions of them. The critters leaves, stems and roots are entrenched in the wood of the wall. The only way to prevent another flower is to take away its source of water. Look to the outside ground and foundation for clues. Even a leaking gutter could be the cause, you'll just need to do some investigating. RScott
Reply:409 didn't kill it. You just mowed the grass-the stuff will return. You need to use a bleach solution to kill it. And wear a mask-this stuff is nasty. You need find the source of water and get that fixed. You have to be very aggresive with treating as it is serious. Good Luck.
Reply:mold is mold from the color of green to dark green then going violet to dark violet and eventually black and hairy... You've got to find the culprit (high level of humidity in your basement or a leak from one of your pipes that drip on that spot)

Use of a dehumidifier should help the situation and looking/repairing any leaks will help.
