I believe you have gotten hold of some weed that was not dried all the way before it was put in a jar to cure. There is some fungus that will be in the bud , but it is very very hard to see without a microscope. The tips of the THC crystals will have little white dots on the end that at first just look like really good shiny THC crystals , but when looked a with at magnifying glass, you will actually see tiny fungus spores at the tip of the THC crystal ! Also when you break apart the nug in high light , you will be able to see almost like a fine mist powder when you break it . That is also the fungus spores. I would not recommend smoking weed that is in this condition. I got some one time and had to chunk it all. Always inspect your weed before you smoke it. imp:
