I got some burrs recently, I think the guy said they are beech burrs but I'm not 100% sure. They've been in my boot for a week so today took them out so I can seal the ends while I think of which way to split them and I noticed on one of the burrs there is a thick white liquid seeping out. It's kind of sticky and looks like PVA glue but it's come out of the wood. Anyone know what it is? I've attached a couple of photos.
Also what is happening with the last one? It looks like there are 3 piths.
