The colloidal chitin protocol I used works. It dispersed evenly and I got growth of a yeast on it when I inoculated a plate using some very old, dried-out fungus we had lying around the lab. The LB plate I inoculated with the same sample showed very different colonies. My field collection method is no good, though. I'm going to try taking cores of fungal context and macerating them next time. I can inoculate my plates with the solution in which I mash 'em up.
