温度、湿度等环境因素直接影响真菌的生长和子实体。研究了森林和实验室环境中生长在同一基质上的木材腐烂真菌物种的多样性。从阿肯色州西北部的森林中采集了10个木腐真菌的子实体标本和24个随机的粗木屑。粗木质碎屑样品在实验室培养箱中培养两个月以促进真菌生长。回收了42个不同种类的木材腐烂真菌分离物，并进行了ITS区序列测定。从森林中分离到的菌株分属于22个不同的分类群，而从生长区划中报告了20个分类群。值得注意的是，从两组观察到的数据并不共享任何分类单元。这些结果表明，即使在相同的基质上生长，环境生长条件也对真菌多样性起着至关重要的作用。
Environmental factors such as temperature and humidity directly affect the growth and fruit bodies of fungi. We studied the diversity of wood decaying fungal species, which have grown on same substrate in forest as well as laboratory environment. Ten specimens of fruit body of wood-decaying fungi and 24 random pieces of coarse wooden debris were collected from the forest of northwest Arkansas. The samples of coarse woody debris were incubated in laboratory-growth chambers for two months to promote the fungal growth. Fourty-two different species of wood-decay fungal isolates were recovered and identified by internal transcribed spacer (ITS) region sequencing. The isolates from the forest belonged to twenty-two different taxa whereas twenty taxonomic groups were reported from the growth compartments. Remarkably, data observed from two sets did not shared any taxon. These results indicated that environmental growth conditions play crucial role on fungal diversity even if grown on same substrates.
