  1. Hyphae are filamentous structures seen in moulds. Pseudohyphae form when yeast cells bud, then elongate and remain attached to each other instead of separating. Hyphae may be septate or aseptate (pics).
  2. Aspergillus and Mucor produce mycelia. Mycelia are a mass of hyphae. Aspergillus has acutely angled branching hyphae, while Mucor has wide-angled hyphae.
  3. Box to diff seb dermatitis from tinea capitis: hair loss or broken hair are seen only in tinea capitis.

Hyphae and Pseudohyphae

  • Hyphae: filamentous mould structures
  • Pseudohyphae: elongated, attached budding yeast cells
  • Hyphae types: septate vs. aseptate

Mycelia and Fungal Identification

  • Mycelia: mass of hyphae
  • Aspergillus: acutely angled branching hyphae
  • Mucor: wide-angled branching hyphae

Differentiating Seborrheic Dermatitis from Tinea Capitis

  • Hair loss or broken hair: seen only in tinea capitis
  • Not present in seborrheic dermatitis
