👉 Oomycetes are a group of unicellular eukaryotic fungi that include the mycelium-producing forms of Aspergillus, Candida, and some species of Ascomycota such as Fungi. They are typically found in soil and other organic matter, growing on decaying plant material or decomposing organic matter. Oomycetes play a crucial role in the ecosystem by breaking down dead organisms and recycling nutrients back into the soil through their mycelial growth.
