It shows that shitake colonizes the
biochar under the conditions mentioned in the experiment. I think biochar could be used to inoculate other logs and maybe shitake will even create conidia (asexual spores) inside the char if left unatended for long periods of time working as a long term inoculum.
Very interesting
