A comparative study of the mycelial phase of Paracoccidioides brasiliensis and Blastomyces dermatitidis reveals that both fungi are very much alike, containing multiple nuclei and nuclear pores, mitochondria, ribosomes, scarce endoplasmic reticulum, intracytoplasmic membrane systems, glycogen, and vacuoles. Shadowed cell walls show fine fibrillar surfaces that contrast with those in the yeast phase. The intracytoplasmic membrane system is continuous with the plasma membrane and is similar to bacterial mesosomes. Granules with light cores and dark rims are observed in the plasma membrane. Live hyphae growing inside a dead hypha are found much more frequently in immersed cultures than in solid-medium cultures, suggesting that breakage of the hypha could elicit this phenomenon.
巴西副球孢子菌和皮炎芽生菌菌丝体阶段的比较研究表明，这两种真菌非常相似，都含有多个细胞核和核孔、线粒体、核糖体、稀少的内质网、胞质内膜系统、糖原和液泡。经投射处理的细胞壁显示出精细的纤维状表面，这与酵母阶段的细胞壁表面形成对比。胞质内膜系统与质膜相连，类似于细菌间体。在质膜中观察到有浅色核心和深色边缘的颗粒。在浸没培养物中比在固体培养基培养物中更频繁地发现活菌丝在死菌丝内生长，这表明菌丝的断裂可能引发这种现象。
