Four types of ascomycete mycorrhizas were found on seedlings of Abies alba grown in pot cultures on mineral soil. One type was formed by Cenococcum graniforme Ferd. & Winge; the fungal partners of the other three types could not be identified. The macroscopic and microscopic characteristics are described. One mycorrhiza appeared to be identical with Type 15 of Haug & Oberwinkler, found in natural spruce stands. Senescent stages of this type are also described. Ultrastructural investigations showed that the dolipore seemed to be the main distinguishing feature between ascomycete and basidiomycete mycorrhizas. Differences in the matrix of the interface and the fungal wall were not stable enough to be used as a distinguishing feature between asco- and basidiomycetes. Dead fungal cells were isolated from the living tissue by plugging of septa with Woronin bodies and walling-over of the plugged septa. Subsequently these isolated dead cells could be colonized by the fungus. The predominant mycorrhization of the fir seedlings by ascomycetes in pot culture with mineral soil is discussed.
在矿质土壤盆栽培养的欧洲冷杉幼苗上发现了四种子囊菌菌根。一种是由颗粒状角担菌（Cenococcum graniforme Ferd. & Winge）形成的；另外三种类型的真菌共生体无法鉴定。文中描述了它们的宏观和微观特征。有一种菌根似乎与在天然云杉林中发现的豪格（Haug）和奥伯温克勒（Oberwinkler）的15型相同。还描述了这种类型的衰老阶段。超微结构研究表明，桶孔隔膜似乎是子囊菌菌根和担子菌菌根之间的主要区别特征。界面基质和真菌壁的差异不够稳定，不能用作子囊菌和担子菌之间的区别特征。通过用伏鲁宁体堵塞隔膜以及堵塞隔膜的壁化作用，从活组织中分离出死亡的真菌细胞。随后，这些分离出的死亡细胞可能会被真菌定殖。讨论了在矿质土壤盆栽培养中，子囊菌对冷杉幼苗的主要菌根侵染情况。
