is a model organism in ecology and evolution. However, its metabolism in its native habitat remains mysterious: it is frequently found growing on leaf litter, a habitat with few carbon sources that can metabolize. We hypothesized that leaf-decomposing fungi from the same habitat break down the cellulose in leaf litter extracellularly and release glucose, supporting growth. We found that facilitation by leaf-decomposing fungi was possible on cellulose and inhibition was common on glucose, suggesting diverse interactions between and other fungi that have the potential to support in nature.
是生态学和进化领域的一种模式生物。然而，它在原生栖息地的新陈代谢仍然神秘：它经常在落叶层上生长，而落叶层是一个碳源很少且它能够代谢的栖息地。我们假设来自同一栖息地的落叶分解真菌在细胞外分解落叶层中的纤维素并释放葡萄糖，以支持其生长。我们发现落叶分解真菌对纤维素可能有促进作用，而对葡萄糖则常见抑制作用，这表明它与其他真菌之间存在多种相互作用，有可能在自然环境中支持它的生长。
