Development
The initial studies on the development of the fruiting bodies in Crucibulum were performed by the brothers Tulasne (1844), Sachs (1855), DeBary (1866), Eidam (1877), and Walker (1920). Collectively, these early researchers determined that basidiospores are produced on club-shaped basidia which line the internal cavity of the peridiole. Basidia typically have 4 spores, attached by a short projection (a sterigma); after being detached from the basidia the spores migrate towards the center of the peridiole concurrently with the collapse and gelatinization of the underlying tissues.

“The American has dwindled into an Odd Fellow—one who may be known by the development of his organ of gregariousness.”

“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
