📐 Design Standards
Labeling Guidelines
| Element | Standard | Notes |
|---|---|---|
| Label Text | Sans-serif, 12-16px minimum | Must be legible at all sizes |
| Leader Lines | 1-2px, straight or angled (not curved) | Point directly to referenced part |
| Nomenclature | Scientific names in italics | Psilocybe cubensis |
| Scale Indicators | Required for anatomical diagrams | "Scale: 1cm" or scale bar |
| Abbreviations | Define in legend or caption | DNA, RNA, ATP, etc. |
Color Coding Standards
- Anatomical Parts: Consistent colors across diagrams (cap = tan, gills = purple-brown)
- Chemical Elements: Standard CPK coloring (C=black/gray, O=red, N=blue, H=white)
- Processes: Use color to show progression (light to dark, cool to warm)
- Emphasis: Bright accent color for key features
- Background: White or very light gray (not distracting)
🧬 Specific Diagram Types
Mushroom Anatomy Cross-Section
Must Include:
- Cap (pileus) - outer layer and flesh
- Gills (lamellae) or pores - with basidia shown
- Annulus (ring) if present
- Stipe (stem) - showing hollow/solid
- Volva if present
- Mycelium at base
- Substrate connection
- Scale bar
Psilocybin Chemical Structure
Elements to Show:
- Skeletal formula (line-angle notation)
- Heteroatoms labeled (N, O, P)
- Molecular formula: C₁₂H₁₇N₂O₄P
- Phosphate group highlighted
- Comparison to psilocin (dephosphorylated form)
- 3D ball-and-stick model (optional secondary view)
Life Cycle Diagram
Stages to Illustrate:
- Basidiospore (microscopic, labeled size)
- Spore germination
- Primordial mycelium
- Mycelial network (rhizomorphs)
- Primordia formation (pinning)
- Young fruiting body
- Mature mushroom (cap open)
- Spore release (back to step 1)
Include: Time estimates, environmental conditions at each stage, circular or spiral layout
🛠️ Technical Specifications
| Property | Standard | Why |
|---|---|---|
| Format | SVG (primary), PDF (archival) | Scalable without quality loss |
| Resolution | Vector (infinite), 300 DPI if raster | Publication quality |
| Line Weight | 2-3px for main outlines, 1px for details | Clarity at various sizes |
| Background | White or transparent | Flexibility in placement |
| Text | Outlined or embedded fonts | Consistent display everywhere |
✅ Scientific Accuracy Checklist
🔬 Verification Process
- ✅ Referenced from peer-reviewed sources
- ✅ Anatomical proportions accurate
- ✅ Chemical formulas verified
- ✅ Terminology scientifically correct
- ✅ Scale and measurements included
- ✅ Reviewed by subject matter expert (mycologist, chemist)
- ✅ Sources cited in caption or legend
- ✅ Simplified appropriately for target audience without losing accuracy
Common Mistakes to Avoid
- ❌ Incorrect gill attachment types
- ❌ Wrong spore print colors
- ❌ Oversimplified chemical structures (losing key functional groups)
- ❌ Anatomical features not to scale
- ❌ Mixing illustration styles within one diagram
- ❌ Poor label placement (overlapping, unclear references)
- ❌ Insufficient contrast for accessibility
