As a mycologist, I have dedicated my career to the study of fungi, a diverse group of organisms that play a crucial role in ecosystems around the world. Fungi are neither inherently helpful nor harmful; their impact on the environment and human life is context-dependent. Let's delve into the multifaceted nature of fungi.
