What is it about?
Mushrooms are the visible fruiting bodies of certain fungi, mainly from the Basidiomycota and some Ascomycetes. Many mushroom-forming fungi play a key ecological role as primary decomposers, breaking down plant materials such as wood, straw, and other agricultural or forestry residues. Their life cycle typically includes spore germination, mycelial growth, and the formation of fruiting bodies that produce new spores. During the mycelial stage, fungi secrete diverse enzymes that enable them to decompose complex plant components and obtain nutrients from lignocellulosic substrates that many organisms cannot utilize. This chapter provides an overview of the common lifestyles of mushroom-forming fungi, the environmental conditions required for their growth and development, and their nutritional requirements. It also summarizes the major enzymatic systems that allow mushrooms to utilize plant biomass, highlighting their ecological importance and their potential for sustainable cultivation using agricultural and forestry wastes.

Why is it important?
Mushroom-forming fungi play a critical role in natural ecosystems because they are among the most efficient organisms capable of decomposing lignocellulosic plant biomass. This ability allows them to recycle nutrients from wood, crop residues, and other plant materials that would otherwise accumulate in the environment. Understanding the physiological characteristics and nutritional requirements of mushrooms is therefore important not only for studying fungal ecology but also for improving the cultivation of edible and medicinal mushrooms. By summarizing current knowledge on mushroom lifestyles, growth requirements, and the enzymatic systems involved in plant biomass degradation, this chapter provides a useful overview for researchers and practitioners working in fungal biology, agriculture, and biotechnology. Such knowledge can support more sustainable use of agricultural and forestry wastes and contribute to the development of environmentally friendly mushroom production systems.
Perspectives
Writing this chapter was a great opportunity to reflect on how much we have learned about mushroom biology, and how many questions still remain open. Over the past decade, genome sequencing has revealed an impressive diversity of enzymes that mushrooms may use to break down plant biomass, yet the functions of many of these genes are still largely unknown. I hope this chapter encourages readers to look beyond what we already know and to explore the many unanswered questions in mushroom physiology. With the rapid development of omics technologies and gene editing tools, the coming years could bring exciting discoveries about how mushrooms regulate growth, utilize complex substrates, and interact with their environments. More than anything, I hope this work inspires further curiosity and research in the fascinating world of mushroom biology.
