真菌菌丝体代表了真菌生活方式的本质，了解菌丝体是如何构建的在真菌生物学和生态学中具有根本的重要性。以前的研究已经检查了初始发育模式或集中在几个菌株，通常是模式物种的突变体，并经常在非协调的生长条件下生长;这些因素目前共同阻碍了对菌丝体结构规则的系统见解。为了解决这个问题，我们在这里使用了一套更广泛的真菌（31种，包括子囊菌门，担子菌门和毛霉门的成员），所有分离自同一土壤，并在标准化的实验室条件下测试了10个建筑特征。我们发现很大的变异性之间的saprobic真菌物种的性状，并检测几个明确的权衡菌丝结构，例如节间长度和菌丝直径之间。在这样确定的限制，我们的文件，否则很大的多功能性菌丝体结构在这组真菌，并没有证据表明性状的“综合征”可能是预期的。我们的研究结果指出了真菌特性的一个重要方面，可能对当地社区内的共存产生影响，以及功能互补性（例如分解，土壤聚集）。
The fungal mycelium represents the essence of the fungal lifestyle, and understanding how a mycelium is constructed is of fundamental importance in fungal biology and ecology. Previous studies have examined initial developmental patterns or focused on a few strains, often mutants of model species, and frequently grown under non-harmonized growth conditions; these factors currently collectively hamper systematic insights into rules of mycelium architecture. To address this, we here use a broader suite of fungi (31 species including members of the Ascomycota, Basidiomycota and Mucoromycota), all isolated from the same soil, and tested for ten architectural traits under standardized laboratory conditions. We find great variability in traits among the saprobic fungal species, and detect several clear tradeoffs in mycelial architecture, for example between internodal length and hyphal diameter. Within the constraints so identified, we document otherwise great versatility in mycelium architecture in this set of fungi, and there was no evidence of trait ‘syndromes’ as might be expected. Our results point to an important dimension of fungal properties with likely consequences for coexistence within local communities, as well as for functional complementarity (e.g. decomposition, soil aggregation).
