F. Sources

The basics..

For solid media use a 2% agar concentration.
For semi-solid media use 0.2-0.5% agar concentration.
Feel free to vary the concentration anywhere in between to get your preferred gel strength.  I usually use around 1.5%.
Measure this by weight, or figure out some sort of conversion if you don't have a scale.  As you can see though, even pretty small measurement errors will give you significant variations in gel strength.

Your carbon source (sugars) should be no more than a maximum 4% concentration.  Lowering this promotes faster and more rhizomorphic growth as the mycelium will actively be seeking out more nutrients rather than being saturated and unmotivated.

Section A: Basic recipes

Potato Dextrose Agar (PDA)(FDA M127)

200 g Potato infusion [dilute to 1L total, ~4g solids]
 20 g Dextrose 
 20 g Agar 
  1 L Distilled water (dH2O)

To prepare potato infusion, boil 200 g scrubbed, sliced(unpeeled) potatoes in 1 liter distilled water for 30 min. Filter through cheesecloth, saving effluent, which is potato infusion (or use commercial dehydrated form). Mix in other ingredients and boil to dissolve. [Dilute to obtain 1 L final volume] Autoclave 15 min at 121
