S.在英格兰南部的两个地方，在许多不同种类的草的根毛中发现了胚根。根毛被一个小的游动孢子感染，进入后，发展成一个含有许多核的变形虫。寄生的结果是根毛显著地膨胀，但不引起其它肥大。变形虫发育成一团孢子，它们排列在一个中空的球体中;所有的孢子都由一层共同的膜粘在一起。新物种不同于唯一的其他描述的物种，S。veronicae，在寄主寄生和肥大的程度产生。其孢子也比S. veronicae。这种新的真菌对它所侵袭的禾本科植物没有明显的损害。
S. radicale was found in the root hairs of a number of different species of grass growing in 2 localities in the south of England. The root hairs are infected by a small swarm spore, which, after entry, develops into an amoeba containing many nuclei. As a result of parasitism, the root hairs swell considerably, but no other hypertrophy is caused. The amoeba develops into a mass of spores which are arranged in a hollow sphere; all the spores are cemented together by a common membrane. The new species differs from the only other described species, S. veronicae, in the host parasitized and in the degree of hypertrophy produced. Its spores are also much smaller than those of S. veronicae. This new fungus does no appreciable damage to the grass plants which it attacks.
