Well I finally got around to do this post.
My dad is a quite a woodsman and has been borderline obsessed with fire starters and tinder. I think he was reading an issue of back woodman (survival oriented magazine) where there was an article on tinder fungus. My dad is 59 and has literally been one of the most active outdoors man I have ever known. He likes a lot of tradition fire starting methods and always trying different things. He had never heard of tinder fungus. After 3 months of talking to fellow outdoorsmen, he couldn't find anyone who had heard of it.
We set out on a quest to find this mysterious tinder. He starting doing research on it trying to find out the areas it grew and the types of trees it was found on.
The best article he found can be found here:
wildwoodsurvival.com/survival/fire/tinder/tinderfungus/true.htmlHere is a good article on false tinder fungus:
wildwoodsurvival.com/survival/fire/tinder/tinderfungus/false.htmlAnd an article on the uses of the it.
wildwoodsurvival.com/survival/fire/tinder/tinderfungus/uses.htmlI did not write the above articles so don't give me the credit.
We were able to easily find the false tinder fungus which seem to work quite well too.
It took use over 8 hours and dozens of times (walking and driving) for our first find. The first one was pretty small and the pieces were around the size of an acorn. The second find yielded pieces about the size of a golf ball. Our last find was the mother load. The piece was a little smaller than a football.
So far we have only found tinder fungus on yellow birch trees. Yellow birch bark is also a great natural fire starter. The oils contained in the bark help it light very easily. It is my theory that most fungus the grow on yellow birch contain these same oils making them burn well.
We have bee experimenting some with it. The real tinder fungus produces a smell that smells a lot like incense. The false tinder fungus smoke smells unpleasant and reminds of burning hair.
Neither variety every seems to form a flame but it does get very hot. A piece the size of the pea burn around 5-7 minutes. You can blow on it as hard as you want and it won't go out. The only way to extinguish it is with water.
I'll try to post some of pics of my samples this weekend.
UPDATE 4/15Here are some pictures of a piece that we found.
The outside has the appearance or charcoal.
The inside as a rusty color.
I wanted to do a small experiment. I broke off a small piece to time how long it burned. It broke off easily with a light strike from a knife. The sample lit very easily with a match.
With only a light breathe of air for one second you can see how hot it gets.
When it is burning it puts out a tremendous amount of heat. Holding your hand above it you could really feel the heat. Here is how it looked after 10 minutes of burning.
I left the piece burning inside for 20 minutes. I then moved it outside. After 5 minutes in the rain it was still burning. This is what it looked like.
After an additional 5 minutes in a light rain it was extinguished.
Conclusions. A small piece will burn for a very long time. I estimate this piece cold have burned for 40 minutes if protected from the rain.
It burns very reliably. Every piece I have tested was only extinguished after consuming itself or upon being exposed to water.
It will stay lit if exposed to light rain for a few minutes, but it would need to be protected from heavy rain.
Family members don't appreciate the smoke when burned inside.
I still need to test how easy it is to light with a spark.
UPDATE 11/2While out hunting yesterday I was fortunate enough to find a lot of tinder fungus.
I really wasn't looking for it, but I found 3 yellow birch trees which had a growing on it. I was able to harvest roughly 7 pounds worth which would fill a shopping bag.
I still need to do my spark testing.
UPDATE 2/27I have also tried it in a fire piston with good success.
My dad has been using it with a striker and flint. He has been able to get it to catch a spark.
No pictures currently but I'll try to put some up eventually.
UPDATE 3/26Here are some pictures of some tinder fungus growing on a yellow birch tree.
