As someone who studied mycology in grad school, doing a project collecting mushroom specimens from grasslands, I really appreciated this game =) I also appreciated that when trying to pick or take some things there was a note that it might disturb the ecosystem. Overall the game is really well executed: the art is beautiful, the variety of music/sfx fits nicely, the required verbs and nouns are clear. It was also fairly long, with lots of different puzzles, so that's quite impressive for a jam submission (especially since this was your second!).
A couple little things you might edit: After I got the power back on, I missed part of the message (seemed like it was missing a "press any key" to hold the message until after I read it). Also I would add "DEPOSIT" specimens as another synonym alternative to "DROP". In scientific writing I am used to seeing "the dried mushroom specimens were deposited at xyz herbarium".
