Abstract—

Axophyllum cavum Trautschold, 1879 (Rugosa: Stauriida: Axophyllidae), a common solitary coral in the Moscovian stage of the Moscow Basin, is briefly redescribed. It is characterized by the small size of adult individuals (a few centimeters) and a high occurrence frequency of rootlet structures on the epitheca that supported the attachment of the coral on the substrate. The extensive collection of small-sized A. cavum (up to 2 cm) with various rhizoid structures and attachment scars from the Staryi Yam locality (Moscow area, Pakhra River, abandoned Yamskoi Quarry) was studied. The morphogenesis of rhizoids was is described in detail.

莫斯科盆地中石炭纪的轴心树（Augophyllum Cavum Trautschold，1879年）的根状结构：形态和起源

摘要-

简要描述了Axophyllum cavum Trautschold，1879年（Rugosa：Stauriida：Axophyllidae），这是莫斯科盆地莫斯科阶上常见的单生珊瑚。它的特征是成年个体的体型小（几厘米），并且上皮上的小根结构出现频率很高，这支持了珊瑚在基质上的附着。研究了来自Staryi Yam地方（莫斯科地区，Pakhra河，废弃的Yamskoi采石场）的各种根状结构和附着疤痕的小型小曲霉（最大2厘米）。详细描述了类根瘤的形态发生。
