Fabulous Fungi at the Fair

Avert your eyes from a post-apocalyptic future in which fearsome fungi destroy civilization and instead look back at some marvelous mushrooms at the 1893 World’s Fair.

The January 22, 1893, issue of the Chicago Tribune reported on “Mushrooms at the Exposition” having “a bed in the Horticultural Building well worth seeing”:

In a darkened room under the pyramid of exotic plants, which occupies the center of the dome of the Horticultural Building, there is an exhibit which is full of interest not only to gardeners and horticulturists but to lovers of fine feasting as well, for what epicure would not be interested in seeing how mushrooms grow. The old story about the growth of mushrooms in a night is a myth. They grow to best advantage in the night, but it takes more than one night for them to mature.

The bed at Jackson Park was made under the direction of John Thorpe Sept. 22. 1892. It was spawned Oct. 1, and the first dish of mushrooms was picked Nov. 1. Last Monday, nearly a bushel of mushrooms were picked from the bed, which is 10×20 feet in size. George Hiller, who has charge of it, is an old mushroom grower.

“Of the process of growing the fungi,” he says, “many book have been written, but the best way for a man to learn how is to go to work and find out for himself.” Any one may raise mushrooms in a cellar, but to raise them successfully in beds is an art. The spawn or germ of the fungi is invisible and for convenience is mixed with a compost of manure into cakes six or eight inches square and one and one-half inches thick. These cakes are broken up and a small portion put into larger cakes of compost, and when the mushrooms make their appearance as small white beads they are placed in beds. When this is done the chief requirement are darkness, an even temperature, moisture, and a few moments’ attention night and morning. The temperature for spawning is 97° and for the healthy growth of the fungus is 57°.

The “pyramid of exotic plants” under the dome of the Horticultural Building at the 1893 World’s Fair housed mushroom beds and later a Mammoth Crystal Cave attractions. [Image from Picturesque World’s Fair. W.B. Conkey, 1894; digitally enhanced.]

The “pyramid of exotic plants” referenced in the article was a small artificial hill constructed to hide the heating equipment needed to keep Horticultural Hall warm during the winter months. Covered with plants, the mound became known as the “Palm Mountain.” The space underneath later was occupied by the Mammoth Crystal Cave attraction from South Dakota.

What happened to these mushrooms after the Crystal Cave was installed is not clear, but Columbian Exposition historian Rossiter Johnson recorded that “Uncle” John Thorpe, Chief of the Horticultural Department, exhibited cultivation of mushrooms in Horticultural Hall. A 240-foot long display of dried specimens of the fungi of New York also stood in the dome gallery of the Horticultural Building. This exhibit by New York State Botanist Charles H. Peck included sixty-one edible species, sixty-three species inhabiting or injuring wood, eighteen species parasitic on cultivated and useful plants, and six species injurious to noxious weeds and animals.

Mushrooms and other edible and poisonous fungi also were exhibited in the U.S. Government Building [Image from Bancroft, Hubert Howe The Book of the Fair (The Bancroft Company, 1893).]
