Mid-culminant mound-&-fb

Both pictures above are from the multicellular stages of the life cycle.  The image on the left shows a mass of cells transforming into a fruiting body with spores maturing on top of a cellular stalk.  The image on the right shows a mound of cells on the left (about half-way through the developmental cycle) and a mature fruiting body on the right.
