Wood-decaying fungi are responsible for the degradation of wood and the alteration in its material properties. (L.) Fr. is one of the most common white-rot fungi colonising coarse wood and standing trees. In recent years, according to their genetic, physiological, and morphological differences, (Ces. and De Not.) Lécuru was identified as an independent species. This article aimed to compare the impact of the degradation caused by both species on the anatomical, physical, and mechanical properties of beech wood. When comparing the degradation caused by different strains of both species, no statistically significant difference was found in mass loss (ML) or moisture content (MC). A relevant correlation between ML and MC was confirmed for both species. Variabilities in the density distribution of the degraded and intact bending samples were found to be statistically different. No relevant difference was observed in the modulus of rupture (MOR) between the two species after each exposure period. A strong linear relationship between the MOR and the dynamic modulus of elasticity was revealed for both species. Both species showed decay patterns typical for simultaneous white rot and soft rot. According to the presented results, the impact of both species on the investigated material properties of wood cannot be considered significantly different.
木腐真菌负责木材的降解及其材料性能的改变。（L.）弗里斯是最常见的定殖于粗木和立木的白腐真菌之一。近年来，根据其遗传、生理和形态差异，（Ces.和De Not.）勒库鲁被鉴定为一个独立物种。本文旨在比较这两个物种造成的降解对山毛榉木材的解剖学、物理和力学性能的影响。在比较两个物种不同菌株造成的降解时，在质量损失（ML）或含水量（MC）方面未发现统计学上的显著差异。证实了两个物种的ML和MC之间存在相关相关性。发现降解和完整弯曲样本的密度分布变异性在统计学上存在差异。在每个暴露期后，两个物种之间的断裂模量（MOR）未观察到相关差异。揭示了两个物种的MOR与动态弹性模量之间存在很强的线性关系。两个物种均表现出同时发生白腐和软腐的典型腐朽模式。根据给出的结果，两个物种对木材所研究材料性能的影响不能被认为有显著差异。
