1。毛霉属(Mucor)：无匍匐菌丝和假根．腐生为 主，引起腐烂.
Mucor is a large genus with 42 known species which are essentially saprophytes. The harmful effects of Mucor in spoilage of food, textile, leather is well known. Sporangiospores are produced within spherical sporangia borne on long unbranched sporangiophores.the sporangiophore grows as an erect hypha; its apical growth ceases and tip swells into a globular structure full of protoplasm.

3梨头霉属（Absidia ）:
菌丝体分化出匍匐菌丝及假根，孢囊梗着 生在假根间弓形的匍匐菌丝上；配囊柄上 长出附属丝包围接合孢子，腐生少数可弱 寄生引起腐烂。

2。根霉属(Rhizopus)：有匍匐菌丝，气生菌丝， 假根，孢囊梗与假根对生，孢子囊球形。
which is often considered similar to Mucor, is however, much different. Many saprophytic species of Rhizopus are used in the production of industrially important substances produces fumaric acid. Rhizopus, as compared to Mucor, has short, stout, stiff sporangiophores which bear black sporangia. The mycelium consists of two kinds of hyphae; the aerial hyphae called stolons, which arch over and root like rhizoids that enter the substratum.Sporangiophores aries from the junction of stolon and rhizoids
小型孢子囊成群聚集在孢囊梗顶端膨大的 球体上，内含1个孢囊孢子。 大型孢子囊 着生在弯曲下垂的孢囊梗顶端内含多个孢 子。
