Myconomy Corporation was a pioneering biotechnology firm that specialized in fungal-derived products, including Mycothread (a mycelium-based textile), Mycoplastic (a biodegradable fungal polymer), Mycosteaks (a protein-rich fungal meat substitute), and Mycofoam (a lightweight fungal insulation material). Though the corporation has long been defunct and its patents expired, its brand name persists as a genericized term—much like "Kleenex" or "Band-Aid" in contemporary usage—to describe a wide range of fungal-based products now manufactured by various independent producers, franchises, and licensed entities.

Myconomy-derived products are widely regarded as the affordable, low-durability option in fungal-based manufacturing. Designed for accessibility rather than longevity, these materials—such as Mycothread, Mycoplastic, and Mycofoam—prioritize sustainability, ease of production, and rapid biodegradability over strength or permanence. Their low cost and simple cultivation requirements make them ubiquitous in resource-limited environments, particularly in fringe colonies and low-income habitats. While they lack the refinement and durability of more advanced composites, their reliability, renewability, and near-universal availability ensure their continued dominance in everyday use, from disposable packaging to makeshift construction.

Among the diverse array of fungal meat substitutes, Mycosteaks stand out as the signature product of Myconomy’s sustenance line. Engineered for versatility, they can be prepared using conventional cooking methods; grilled, broiled, sous vide, or pan-seared, and are even designed to mimic the appearance of raw meat, complete with a protein-based "bleeding" effect. While the taste and texture are not indistinguishable from animal-derived steak, they are widely regarded as delectable, even by discerning consumers, including self-described picky eaters and supertasters.
