为了评估绒纹平革菌（Phanerochaete velutina）资源利用与菌丝生长之间的关系，在3种不同土壤量下，利用3种不同大小的木块进行了土壤微观环境试验，模拟了不同有效养分量。在土壤微环境中培养27 d后，最小木块的失重率最高，但接种前2个月纯培养定殖的失重率在不同木块大小之间没有显著差异。在最小的木块中也观察到最大的菌丝生长，并且与木材腐烂呈正相关。不同木材尺寸的菌丝盖度与木材质量损失率的回归曲线斜率相同，但小木块的菌丝盖度与绝对木材质量损失率之间的斜率比大木块大。这些结果表明，菌丝在土壤中寻找新资源的强度取决于木材资源利用的百分比，而不是从木材中获得的绝对碳量。
To assess the relationship between resource use and hyphal growth in a cord-forming basidiomycete, Phanerochaete velutina, soil microcosm experiments were conducted using wood blocks of three different sizes in three different soil quantities, thereby simulating the different amounts of available nutrients. The highest percentage weight loss was observed in the smallest wood blocks after a 27-d incubation period in soil microcosms, although the percentage weight loss over the 2-month pure culture colonization prior to inoculation was not significantly different among various block sizes. The greatest hyphal outgrowth was also observed in the smallest wood blocks and was positively associated with wood decay. The slopes of the regression lines between hyphal coverage and percentage wood mass loss were identical among different wood sizes, but the slopes between hyphal coverage and absolute wood mass loss were steeper in the smaller wood blocks than that in largest one. These results suggest that the level of intensity of mycelial foraging for new resources in the soil depends on the percentage of the amount of wood resource utilized, and not on the absolute amount of carbon obtained from the wood.
