近年来，北美东部的森林病理学家对香脂冷杉（Abies balsamea (L.) Mill.）的腐烂进行了四项单独的调查。在这些研究的早期，很明显，关于导致活体香脂冷杉树腐烂的真菌的身份的现有观点需要进行大量修改。树干腐烂被证实主要是由 Stereum sanguinolentum Alb 引起的。和施瓦。前炸薯条；然而，以 Corticium galactinum (Fries) Burt 为首的五种真菌被发现与大多数白色丝状屁股腐病有关，还有两种真菌，Coniophora puteana (Schum. ex Fries) Karst。和猪苓香脂 Peck 与大多数棕色立方体对接腐病有关。迄今为止，茯苓（Peck）囊。据信，P. balsameus 和 P. balsameus 分别导致了该物种的几乎所有白色和棕色屁股腐病。讨论了地点对活体香脂冷杉腐烂的影响，以及九种主要树种中每一种的腐烂程度和种类。
Four separate investigations of decay in balsam fir (Abies balsamea (L.) Mill.) have been carried out in recent years by forest pathologists in Eastern North America. Early in these studies it became apparent that the existing ideas concerning the identity of the fungi responsible for decay in living balsam fir trees required considerable revision. Trunk rot was confirmed as being caused mainly by Stereum sanguinolentum Alb. and Schw. ex Fries; however, five fungi, headed by Corticium galactinum (Fries) Burt, were found associated with most of the white stringy butt rots, and two fungi, Coniophora puteana (Schum. ex Fries) Karst. and Polyporus balsameus Peck, were associated with most of the brown cubical butt rots. Hitherto Poria subacida (Peck) Sacc. and P. balsameus were believed to cause practically all white and brown butt rots, respectively, in this species. The effect of site on the decay of living balsam fir is discussed, as is the extent and kind of decay with which each of the nine predominant h...
