The community assembly of wood-inhabiting fungi follows a successional pathway, with newly emerging resource patches being colonised by pioneer species, followed by those specialised on later stages of decay. The primary coloniser species have been suggested to strongly influence the assembly of the later-arriving community. We created an artificial resource pulse and studied the assembly of polypores over an $11\text{yr}$ period to ask how the identities of the colonising species depend on the environmental characteristics and the assembly history of the dead wood unit. Our results support the view that community assembly in fungi is a highly stochastic process, as even detailed description of the characteristics of dead wood (host tree species, size, decay class of the resource unit, its bark cover and how sunken it is to the ground) and the prior community structure provided only limited predictive power on the newly colonising species. Yet, we identified distinct links between primary and secondary colonising species and showed how the spatial aggregation of dead wood had a great impact on the community assembly.

居住木材的真菌的群落组装遵循连续的途径，新出现的资源斑块被先驱物种定殖，随后是专门用于腐烂后期的物种。已经提出主要的定居者物种强烈影响后来到来的群落的组装。我们创建了一个人工资源脉冲，并研究了在$11\text{年}$这段时间来询问殖民物种的身份如何取决于环境特征和枯木单元的组装历史。我们的结果支持这样一种观点，即真菌中的社区组装是一个高度随机的过程，甚至更详细地描述了枯木的特征（寄主树的种类，大小，资源单元的腐烂等级，其树皮的覆盖度以及对木材的沉没程度）。地面）和先前的群落结构仅对新定居的物种提供了有限的预测能力。但是，我们确定了主要和次要殖民物种之间的独特联系，并显示了死木的空间聚集如何对群落聚集产生巨大影响。
