利用形态学、细胞化学和个体发育特征描述了一种新的内生菌根真菌--冠状球囊霉（Glomus coronatum Giovannetti）。孢子呈橙黄色至红棕色，球状，外壁透明，在酸性环境中膨胀成粗糙的火焰状柱状。孢子果是由对着菌丝生长出细菌丝分枝，逐渐覆盖原来的孢子而形成的。许多被菌丝套包裹的孢子同时形成，并结合形成孢子果。讨论了孢子和子实体的个体发育在描述新分类群中的重要性。关键词：菌根，VA菌根真菌，分类学，个体发育，冠状球囊霉。
The new species of endomycorrhizal fungus Glomus coronatum Giovannetti is described using morphological, cytochemical, and ontogenetic characters. Spores are yellow–orange to red–brown, globose, with a hyaline outer wall layer expanding into roughened, flamelike columns in acidic mountants. Sporocarps are formed by the growth of fine hyphal branches from the subtending hyphae, which gradually cover the original spore. Many of the spores enveloped in the hyphal mantle are formed simultaneously and coalesce to form the sporocarp. The importance of the ontogeny of spores and sporocarps in the description of new taxa is discussed. Key words: mycorrhizae, VAM fungi, taxonomy, ontogeny, Glomus coronatum.
