Wasp's Nest Slime Mold

Metatrichia vesparium


These stalked fruiting bodies were found growing in clusters. Several empty sporangia (goblet-shaped, spore containing structures) were present, but there were partially intact (and remnants of) apical caps in places as well. There were also several orange masses of capillitium, fluffy structures that aid in spore dispersal, ultimately springing open the sporangia through their coiled force.


Growing on Water Birch (Betula occidentalis) at a forest edge.
