The multibrystal has replaced its ancestor where their ranges overlap. It has adapted for life beneath much larger, leafy flora by developing multiple caps growing from a single base for gathering the little light that filters down. The exact number of caps varies between individuals, usually being 3 or 5. In addition to the light-gathering benefit, the multiple caps increase the number of spores it can produce, which in turn increases the chance that one will eventually germinate—with the rise of seed-producing shrooms which can bypass leaf litter, this is vital for surviving its detritivorous competition.
The spores of the multibrystal can survive in air, but are not wind-borne due to a lack of wind on the forest floor. Instead, they are most frequently spread by water from floods, and by fauna that happen to pick them up in their integument when they pass by. This is already technically the case in its ancestor as a result of flora growing around it, but in the multibrystal has adapted specifically for it by developing microscopic hooks on its spores that aid them in catching on fibers.
Much like its ancestor, the multibrystal is relatively slow growing for its size and doesn't live very long, only about 10 years. Despite its greater mass, it reaches full size in about the same time—one year.
