Propagation & Germination
Pre-treatment: Surface sow spores on sterilized milled sphagnum peat moss in sterilized flats with drainage holes. Water with distilled water and seal flats with clear plastic wrap. Place under 60 watt soft incandescent lights for 12 hours per day. Maintain a constant temperature of 20 to 25C.
Establishment: Fronds are collected by hand in July and August when the indusium begins to lift and spore color is black. The species is common in moist forests and streambanks, from lowland to mid-montane elevations. It is found across Canada, the upper Mid-Western states and Washington, Idaho and northwestern Montana.
