This extinct mushroom is the only known fossil tropical mushroom ever found.
One of the smallest members of the so-called inky cap family, this specimen
likely grew on the bark of the algarrobo tree with others of its kind. When the
cinnamon-colored mushroom was overrun by a glob of resin, a tiny mite grazing
on its cap was entombed forever in the very act of dining (see mite lower right).
