Summary of Differences in Use:

Stereo (Dissecting) Microscopes in Mycology

• Use: Low-power (typically 10×–50×, sometimes up to ~100×) reflected light viewing of macroscopic fungal parts—e.g. ascomata, sporophores, mold colonies, cortices—without the need to slice or mount samples.
• Applications:
  • Observing surface colonization on materials (like paint with Chaetomium as shown in image top-left).
  • Inspecting fruiting body structures (sporangia, pigments, textures).
  • Preparing dissected parts for slide mounting using fine tools.
• Strengths: High working distance and depth of field, letting you manipulate samples while viewing them.
• Limitations: Insufficient magnification to see spores or hyphae clearly—ID-quality observation requires at least 100×, ideally 400–1000×

Compound Microscopes in Mycology

• Use: High magnification viewing (40×–1000×) using transmitted light—ideal for hyphae, spores, asci, basidia, and microstructures.
• Applications:
  • Measuring spore shape, size, wall ornamentation—critical for species ID (images bottom: spores at ~400×).
  • Using stains and oil-immersion lenses to highlight cellular details.
  • Employing phase-contrast, DIC, or fluorescence for advanced structural imaging.
• Strengths: High resolution and detail, essential for microscopic taxonomic work.
• Limitations: Requires thin, mounted specimens; lower working distance; more sample prep.

Practical Workflow in Mycology

1. Stereo scope stage: Start with surface-level observation—examine whole fruiting bodies, isolate spores or tissue pieces.
2. Prep stage: Use dissecting microscope to pick and prepare thin sections.
3. Compound scope stage: Transfer prepared sections to slides and view under high magnification, using stains and oil-immersion if needed.
