Observation 205493: Trichoderma viride Pers.

When: 2015-06-01

Collection location: Lower Meramec Park, St. Louis Co., Missouri, USA [Click for map]

Who: weed lady (Sylvia )

No specimen available

Note I called this Fungi and doubtful. Suspect this is something other than a fungus. The color was great (teal green), so I collected it. Maybe someone will have an idea as to its identity.

For taking a look at my observation. Yes, this could be it. Just glad to get it figured out to the genus level. If this is so common I am surprised there are not more observations of it. The color makes it hard to pass up. I saw that it was one of your observations, so I asked you to take a look. Thanks again.

Yes, this very well may be Trichoderma viride. It grows almost everywhere on earth.

This observation resembles other observations of Trichoderma: observation 138455 and observation 149271. Perhaps others.

New characteristic observed on this specimen. The green rubs off when I run my finger across it. Guess that does rule out lichen. When you rub your finger over the white, green is beneath. Could this be a slime? Maybe a dumb question.
Whatever its name the color is great. I have three pieces of this if anyone is interested.

I don’t think so

You could no doubt prove me wrong, but this looks more like an unlichenized fungus to me…
