Here is a chunk of Tinder Fungus I knocked off. I collect it when I can and wanted to share for some who may have never realized the free, always spark ready tinder in our woodland never had trouble getting a fire started with a ferro rod and steel in the rain and its very lightweight, long enough burning to produce a coal, and honestly is my favorite tinder! The trick that works for me is to cut a small chunk, grind er up into a rough powder and set it up on a dry leaf. Hit er with a spark shower and it coals up like an incense. Get it into yer nest and its a newborn fire! I will also use it for my friction fires. I pack some ground up fungus into the baseplate notch and in a pretty short time when yer poplar dust begins to heat up, the fungus will begin to coal as well. Just adds a little more heat to yer success. I hope this was helpful and good luck knockin off the tinder fungus!
