    Hi there!

    A short while ago, I went on a little excursion in the woods (if you can call really them that) nearby and collected some infested chunks of wood, some mosses, some dirt, and some bugs to make a lil biome in a jar and see what happened. Initially, the jar was growing some A. pyxidatus (the fruit of which has since wilted away for now) and some A. auricula-judae (still going strong!) from separate chunks of wood. However, over the last few days, a real STRONG mold has grown on the barkside surface of a chunk of maple that I stuck in there. It looks like it might potentially be a Lichen or an Aspergillus to me, but I'm not certain. Anyone have any good guesses? Is it potentially the fungal component to a lichen that hasn't established yet?

    And furthermore: is it safe to keep what you think it may be in an enclosed jar? I know with a lot of Aspergillus molds, you have to worry about mycotoxins and breathing around them, but this a very small, enclosed amount, and the jar will (likely) not be opened (inside the house at least). Anyone have any concerns?

    Let me know what you think!

    Hi @Foxdodge
    Interesting project!
    Possibly Trichderma cf. viride, re the colour & apparent substrate.
