Understanding the mechanisms underlying wood decay basidiomycete community dynamics is crucial for fully understanding decomposition processes, and for modelling ecosystem function and resilience to environmental change. Competition drives community development in decaying woody resources, with interactions occurring at a distance, following physical contact, and through specialised relationships such as mycoparasitism. Outcomes of combative interactions range from replacement, where one mycelium displaces another, to deadlock, where neither combatant captures territory from the other; and a spectrum of intermediate outcomes (i.e. partial or mutual replacement) lie between these extremes. Many wood decay basidiomycetes coexist within a resource, in a complex and dynamic community, and new research techniques are focussing on spatial orientation of interactions in 3 dimensions, as opposed to historical two-dimensional research. Not only do interactions drive changes in species composition and thus wood decomposition rate, they also may have industrial applications in biocontrol of pathogenic or nuisance fungi, enzyme production, and in the production of novel antifungals and antibiotics. Altogether, fungal interactions are a fascinating and important field of study.

理解木材腐烂担子菌群落动力学的基本机制对于充分理解分解过程，以及对生态系统功能和对环境变化的适应力进行建模至关重要。竞争通过腐烂的木本资源推动社区发展，在远距离接触之后，通过物理接触并通过特殊的关系（如霉菌寄生）发生相互作用。战斗互动的结果从替换（一个菌丝体取代另一个菌丝体）到僵局（两个战斗员都不从另一个菌丝夺取领土）到僵化不等。在这些极端之间存在一系列中间结果（即部分或相互替换）。在一个复杂而动态的社区中，许多木材腐烂的担子菌共存于一种资源中，与历史的二维研究相反，新的研究技术集中在3维相互作用的空间取向上。相互作用不仅驱动物种组成的变化，进而驱动木材分解速度的改变，而且在病原性或滋扰性真菌的生物防治，酶的生产以及新型抗真菌剂和抗生素的生产中也可能具有工业应用。总之，真菌相互作用是一个有趣而重要的研究领域。
