Single-species and two-species interactions.

Total N in needles and mycelium (Total N), total fungal biomass C produced and needle C decomposed (mass loss + mycelial C) of old litter and new litter, inoculated with Gymnopus androsaceus, Mycena epipterygia or Helotiales (new litter only). Old and new litters were combined after inoculation with the same (single-species) or different (two-species) fungal species. All data is given per g of needles at the start of the experiment. ‘Old litter’ represents needles incubated for a total of 10 month and ‘New litter’ represents needles which were placed on top of the old litter after 5 months. Data are mean ± SEM (for numbers of replicates, see Fig. 2).本数据集涵盖以下指标：接种安杜拉裸柄伞（Gymnopus androsaceus）、翅状小菇（Mycena epipterygia）或柔膜菌目（Helotiales，仅用于新枯落物）的老枯落物与新枯落物的针叶与菌丝体总氮（Total N）、生成的总真菌生物量碳，以及针叶碳分解量（质量损失与菌丝体碳之和）。 在以相同（单菌种）或不同（双菌种）真菌完成接种后，将对应老枯落物与新枯落物进行合并。 所有数据均以实验初始阶段每克针叶为计量基准。其中“老枯落物”指总培养时长为10个月的针叶，“新枯落物”指于实验开展5个月后放置于老枯落物上方的针叶。 数据以平均值±标准误（mean ± SEM）形式呈现；重复样本数量详见图2。
