This study reports a test of the hypothesis that mesh litter bags restrict access of vegetative fungal structures to confined substrate. Unconfined birchwood swab sticks lost more dry weight during a field incubation than confined ones. Samples in fine mesh bags lost more weight than those in coarse mesh bags. Significantly higher numbers of mycelial strands and rhizomorphs were found on unconfined samples. The number of fungal structures was significantly correlated with weight loss of individual samples. It is suggested that the inhibitory effect is most significant in environments where higher fungi are the dominant decomposing organisms.
本研究报告了一项关于网袋限制营养真菌结构接触受限基质这一假设的试验。在田间培养期间，未受限的桦木拭子棒比受限的桦木拭子棒损失的干重更多。细网袋中的样本比粗网袋中的样本损失的重量更多。在未受限的样本上发现的菌丝束和菌索数量明显更多。真菌结构的数量与单个样本的重量损失显著相关。有人认为，在高等真菌是主要分解生物体的环境中，这种抑制作用最为显著。
