The text of the design is in Latin, in keeping with the species names.
The multi-hued spore print in the center sprouts into the four Horns of Fungal Plenty. The labels on each horn loosely translate as:
Esculienti et Gustati — (Edible and Culinary)
Formosi et Mirabiles — (Beautiful and Wonderful
Tinctorii et Ornamentales — (Dyeing and Art)
Medici et Enthei — (Medicinal and Spiritual)
Representative Pacific Northwest mushrooms, conks and truffles are illustrated emerging from each horn and are labeled in the corners.
