Litter input is an important source of C and nutrients in forest soils that are liberated and utilized during decomposition. We have investigated the long-term decomposition of Picea abies and Calamagrostis villosa litters in montane spruce forest and the litter-associated fungi. The two litter types differed in initial nutrient content and decomposed at different rates, but in both cases, significant residual mass was left after five years of decomposition – over 30% of the initial mass of Calamagrostis litter and 40% of Picea litter. The litters harbored different fungal communities, though these tended to converge over time. The initial fungal community was dominated by Ascomycota, while the share of Basidiomycota and Mucoromycotina/Mortierellomycotina increased towards the end of the experiment. Individual litter fungi showed variable preference to litter type, succession time and duration of occurrence and we propose these as potential taxon-specific traits requiring further investigation.

废弃物输入是森林土壤中碳和养分的重要来源，在分解过程中会释放和利用碳和养分。我们已经研究了山地云杉林和与垃圾相关的真菌中的云杉云杉和长毛云杉凋落物的长期分解。两种垫料的初始养分含量不同，分解速率也不同，但是在两种情况下，分解五年后都留下了明显的残留量–卡拉马格斯垫料初始量的30％和云杉的初始量的40％以上垃圾。垃圾有不同的真菌群落，尽管随着时间的推移它们趋于融合。最初的真菌群落主要为子囊菌，而担子菌和毛霉菌/门氏菌的比例在实验结束时有所增加。单个凋落物真菌对凋落物类型，演替时间和发生持续时间表现出不同的偏好，我们建议将其作为潜在的分类群特质，需要进一步研究。
