Stereum spp.的同核菌株组合之间的配对。在非自体细胞核迁移后，产生广泛的贴伏、退化的菌丝体区域。气生结晶丝，最大35 μ m宽，≥ 100 μ m。6厘米长，出现从这个菌丝体在局部灶似乎作为水槽菌丝资源。这些细丝被证明是双环叔醇，（+）-torreyol。较大的细丝是细长的亚单位的聚集体，其通常围绕纵轴急剧螺旋并且独立地和顶部地延伸，即使暴露于大气中。（+）-香榧醇从有机溶剂中重结晶或通过升华导致在形状和大小上类似于菌丝体形态发生的图案。在退化菌丝体中产生新的蛋白质，证明了来自两个祖细胞的核而不是线粒体DNA限制性片段长度多态性的组合。从退化菌丝体的继代培养和担子孢子衍生的后代表现出显着的发育变异和不稳定性。
Pairings between combinations of homokaryotic strains of Stereum spp. give rise, following immigration of non-self nuclei, to extensive zones of appressed, degenerative mycelium. Aerial, crystalline filaments, up to 35 .mu.m wide and .gtoreq. 6 cm long, emerge from this mycelium at localized foci which appear to act as sinks for mycelial resources. The filaments are shown to be the bicyclic tertiary alcohol, (+)-torreyol. The larger filaments are aggregations of elongated sub-units which generally spiral steeply around the longitudinal axis and extended independently and apically, even when exposed to the atmosphere. Re-crystallization of (+)-torreyol from organic solvents or by sublimation results in patterns resembling those of mycelial morphogenesis in both shape and size. Novel proteins are produced in the degenerate mycelium, which the combination of nuclear but not mitochondrial DNA restriction fragment length polymorphisms from both progenitors is demonstrated. Subcultures and basidiospore-derived progeny from the degenerate mycelium exhibit marked developmental variation and instability.
