调查了安大略南部常见蕨类植物的39个种和变种是否存在VAM。对木贼属（Equisetum spp.）和两种石松属（Lycopodium spp.）通常是非VA菌根。这两个物种的Botrychium广泛VA菌根，而Filicales一般中度殖民，虽然孤立的岩石露头和裂缝的植物往往是非VA菌根。根据Baylis的根形态和真菌营养理论对这些观察结果进行了讨论。此外，还列举了可能与VAM混淆的各种根栖真菌。
Thirty-nine species and varieties of common Pteridophytes of southern Ontario were surveyed for the presence of VAM. The sporophytes of the three Equisetum spp. and the two Lycopodium spp. examined were usually non-VA mycorrhizal. The two species of Botrychium were extensively VA mycorrhizal, while the Filicales were in general moderately colonized, though plants from isolated rock outcroppings and crevices were often non-VA mycorrhizal. These observations are discussed in light of Baylis' theory of root morphology and mycotrophism. In addition, various root-inhabiting fungi which could be confused with VAM are illustrated.
