Twenty-six biochemical tests were used to study cultures of basidiomycetes isolated from roots of fruit-trees and other plants. The results enabled isolates to be placed into one of sixteen groups. Three of these groups were identified as Collybia drucei, Corticium utriculicum and Heteroporus biennis by matching their biochemical reactions with those of isolates from fruiting bodies of these fungi. This suggests that the other groups might also correspond to species. The three named fungi are indigenous, the first two not having been recorded elsewhere. Thus, root infections by these fungi may have originated from the indigenous fungal flora. Isolates of C. utriculicum and Stereum purpureum which were indistinguishable in culture were also separated using biochemical tests.

担子菌的一些额外菌丝培养物的生化特征

26 项生化试验用于研究从果树和其他植物根部分离的担子菌培养物。结果使分离物能够被置于十六组中的一组。通过将它们的生化反应与来自这些真菌子实体的分离物的生化反应进行匹配，将其中三个组确定为 Collybia drucei、Corticium utriculicum 和 Heteroporus biennis。这表明其他组也可能对应于物种。这三种命名的真菌是本土的，前两种没有在其他地方被记录。因此，这些真菌引起的根部感染可能源自本地真菌菌群。在培养中无法区分的 C. utriculicum 和 Stereum purpureum 的分离物也使用生化测试进行了分离。
