从英国西南部地区收集了被 D. concentrica 侵染的白蜡树 (Fraxinus excelsior) 枝条，并分析了腐烂模式。一个显着的特点是树枝上的 D. concentrica 个体数量有限，但它们占据的木材长度和体积相当大。这表明这种真菌是主要定殖者并且定植可能是通过潜伏入侵进行的。在麦芽琼脂上的最佳温度下，菌丝延伸很快，并且 D. concentrica 比附着在枝条上的担子菌更能耐受低水势。它是一种好斗的真菌，它取代了在培养中与其配对的大部分生物体，尽管结果被水势和气体状态改变，有时相当大。
Attached ash (Fraxinus excelsior) branches, colonized by D. concentrica, were collected from locations in South-West Britain [UK] and the patterns of decay analyzed. A notable feature was the limited number of individuals of D. concentrica in branches and the considerable lengths and volumes of wood that they occupied. It is suggested that this fungus is a primary colonizer and that colonization may be by latent invasion. Mycelial extension, at optimal temperatures on malt agar, was rapid and D. concentrica was more tolerant of low water potentials than basidiomycetes found in attached branches. It is a combative fungus and it replaced most of the organisms with which it was paired in culture, although the outcome was modified, sometimes considerably, by water potential and gas regime.
