Anyone want to try to grow some Gyms?
Here's an old thread with good information from Teonanacatl38, buteo, and others.
In general, it seems like people have succeeded using substrates of wood chips and sawdust supplemented with grain, bran, and soil. Casings appear to be standard (coir, soil, etc), and reported fruiting temperatures range from below 20C (68F) to 27C (80F). Several people report that Gyms are fairly easy to fruit.
I have a culture which I started a while ago from what I was told were G. dilepis spores. I'll get that out of the fridge and put it on some new plates in the next few days here. It'd be cool if we could build up some knowledge and documentation about growing these!
