How To Dry Birch Polypore Like A Pro
Drying a birch polypore, commonly known as a bracket fungus (Fomitopsis betulina, formerly Piptoporus betulinus) at 50°C (122°F) is a very good and safe choice. This temperature is high enough to evaporate the moisture, but low enough not to destroy valuable medicinal compounds (such as polysaccharides) or scorch the mushroom.
However, bracket fungi and polypores are much denser, more compact, and hold more moisture deep within their tissue than typical cap-and-stem mushrooms (like porcini). Therefore, this process takes significantly longer.

Estimated Drying Time:
- 12 to 24 hours for thinly sliced pieces.
- Up to 36 hours if the slices are slightly thicker or the mushroom was very fresh and moist.
The Golden Rule: Slicing
This is the most crucial step. You must cut the polypore/bracket fungus into very thin slices. If you leave thick chunks or try to dry whole specimens, they will only dry on the outside. Moisture will remain trapped inside, which will lead to mold growth in the storage jar within just a few days after drying.
How to Check if the Mushroom is Properly Dried:
Do not rely solely on time, judge by appearance and touch:
- The slices must be lightweight and stiff.
- When bent, they should snap with a distinct crack (like a dry potato chip).
- If a slice bends, feels rubbery, or feels cool/damp to the touch in the center, it still needs more drying.
Practical Tips for the Dehydrator:
- Spacing: Arrange the slices on the trays with space between them so air can circulate freely around each piece.
- Tray Rotation: If your dehydrator does not have highly efficient, even air circulation, swap the trays (top to bottom) every 3–4 hours.
- Cleanliness: It is best not to wash these mushrooms with water before drying, as they absorb it like a sponge. Instead, clean them thoroughly with a brush or knife to remove dirt and debris. If you absolutely must rinse them, do it very quickly and pat them completely dry with a paper towel before placing them in the dehydrator.
I use this food dehydrator for drying mushrooms like the Birch Polypore, and I am very happy with it.
The Final Test (Very Important!)
After removing the mushrooms from the dehydrator and letting them cool to room temperature, place them in a glass jar with airtight lid. Leave it for 24 hours.
- If even the slightest condensation or moisture appears on the inside walls of the jar, it means the mushrooms are not 100% dry. You must immediately remove them from the jar and put them back in the dehydrator for a few more hours. Otherwise, they will mold.
