Where do digestive enzymes come form on mushrooms and other fungi?

Digestive enzymes in mushrooms and other fungi are produced by specialized cells in their mycelium, the vegetative part of the fungus. These enzymes are secreted into the surrounding environment to break down complex organic materials, such as cellulose and lignin, into simpler compounds that the fungus can absorb as nutrients. This extracellular digestion allows fungi to decompose a wide variety of organic matter, playing a crucial role in nutrient cycling within ecosystems.
