I thought Id correct people regarding green molds and the identification of these. Trichoderma does not normally contaminate substrates, and is much more likely to develop on moist casings and compost as well as ON fruitbodies. It develops first in scales of grey cotton that soon develop into dark forest green as it develops spores. The more common mold Aspergillus grows on substrates and casings but never or very rarely on fruitbodies. Firstly it is a cotton white and spreads this way, turning light to dark green in the centre as it spreads. If its on your substrate its probably aspergillus or penicillium.
Just to add that there are many people asking questions about green mold over and over. Please don't compare problems or situations involving green mold if you're not sure about the kind of contamination you have, it's like comparing apples to lemons and sometimes both are green too. It's hard for us to respond "green does this" or "green does that" when we don't know which green people are referring to.
Macroscopic identification of a contamination is nearly impossible. There are a few notable exceptions. There are at least four or five different types of contamination that are both green and common to mushroom cultivation. There are many more that are green and uncommon to mushroom cultivation, but are still found from time to time.
