It is perhaps as important to have a source of fresh spores stored away
from direct UV light. Good luck on the agar cultivation, though.
BTW, parasol or Lepiota sps. usually take a compost pile or leave pile to
get established. In my area, Thatcher ants collect tiny Douglas fir twigs
and spend needles to create large mounds of debris, which they then grow
Lepiota rhachoides on. Sometimes a Cordyceps or disease attacks these ant
mounds, and cause the ants to die. Shortly thereafter there are major
fruitings of Lepiota rhacoides!
