Mushroom growers tend to artificially inoculate their growing medium (substrate) using a spore syringe, spore print, or swab. Inoculation occurs when a spore lands on a surface that provides it with favorable growing conditions. In nature, they are usually transported by the wind or on an animal’s fur. When a mushroom releases its spores, they must find a suitable environment in which to grow. Below we will explore how this spore develops and grows, eventually producing mushrooms and beginning the life cycle again. However, it starts its life as a tiny spore, invisible to the naked eye. Mycelium can grow to incredible sizes, sometimes covering thousands of acres of land. To fully understand this process, it is necessary to look more closely at the various stages of mycelial growth. Unlike animals, which require a male and female partner, fungi are hermaphroditic, playing both mother and father to their offspring. However, many fungi rely upon sexual reproduction and require a partner. Some Ascomycetes, including cordyceps, can also reproduce without a mate. Microscopic fungi like yeasts also have very different life cycles and reproduce asexually by “budding” rather than mating. Please note that the process differs slightly for Ascomycetes such as cup fungi and morels. This article will focus on Basidiomycetes, a class of fungi that includes gilled mushrooms, polypores, puffballs, boletes, and more. However, most varieties follow a somewhat similar pattern which we will describe below. The mushroom life cycle varies slightly from species to species. The Life Cycle of Mushrooms: Sexual and Asexual Reproduction So, without further ado, let’s get up close and personal with mushrooms. Anyone interested in mycology will find it a worthwhile subject, especially individuals hoping to grow their own. This article explains the life cycle of mushrooms and provides a fascinating insight into how fungi reproduce and grow. In fact, mushrooms are sometimes known as “fruiting bodies.” Therefore, many people compare mycelium to a tree and mushrooms to its fruit. Their role is to produce and release spores, the fungal equivalent to seeds. The fungus spends most of its life cycle in this state and only forms mushrooms under specific conditions. It breaks down organic matter and absorbs nutrients from its surroundings, playing a vital role in the ecosystem. The mycelium tends to remain hidden underground or inside rotting wood or trees, explaining why many people are unaware of its existence. It is a mass of fine, interwoven strands called hyphae. The bulk of a fungus is an extensive network known as the mycelium. For example, did you know that mushrooms are actually the reproductive organs of a much larger organism? Although the average American consumes 2.2 pounds of mushrooms each year, not everyone understands where they come from. ![]()
