Structure of Agaricus Bisporus Mushroom
The structure of Agaricus can be described as follows:
Vegetative structure
The mycelium is comprised of interconnected hyphae and forms the fungal organism’s vegetative component. It permeates the substrate, often hiden below its surface and is vital for nutrient absorption and growth.
Primary mycelium
It originates from the germination of uninucleate basidiospores containing either the positive or the negative strains, the cells are initially monokaryotic. This stage is transient, as they soon become binucleate through the fusion of two compatible hyphae.
Secondary mycelium
The secondary mycelium, known as dikaryotic, originates from the primary mycelium. Following the fusion of hyphae from two opposing strains, one nucleus migrates to the other, resulting in the formation of binucletae secondary mycelium. This phase is characterized by longevity and abundance.
Tertiary mycelium
The secondary mycelium extends extensively underground and undergoes organization to create specialized tissue, forming the fruiting body or basidiocarp. This structure resembles an umbrella emerging above ground and consists of dikaryotic hyphae. Referred to as tertiary mycelium, these hyphae remain subterranean. They are septate and branched, with communication between cells facilitates by a central pore in the septum.
Fruiting body or Basidiocarp
The transition to the fruiting body in Agaricus bisporus occurs due to a significant shift in hyphal behaviour. Instead of spreading diffusely, the hyphae grow closely together, forming an intertwining structure. This results in a solid substrate that produces a similar arrangement in the mushrooms fruiting body.
Agaricus Bisporus
Agaricus bisporus is a type of edible basidiomycete fungus. Agaricus bisporus common name is button mushroom. It is naturally found in grasslands, fields and meadows across Europe and North America. Agaricus bisporus structure is characterized by a cap, gills, stem, and mycelial network. In this article, we will cover Agaricus bisporus classification, structure, and more in detail.
