  1. Nice! Forgive my basic question, but what do you mean with chemical analysis? Do you have a mobile set? And how does it work exactly? Posted 7 days ago
    1. I do have a mobile set, but I usually do all of my tests and note-taking once I get home.

      The test kit consists of the aforementioned reagents (in aqueous solution) in dropper bottles. I almost always use them on boletes as color changes on the pileus, flesh, and pores can help differentiate species with similar morphologies.

      Would you like me to include some shots of my chemical analyses in future posts?

      1. Hmmm, that's an interesting question. I would have a personal interest in it, but it would violate our rule (or guideline) to try and avoid objects, non-natural elements and such. Perhaps you can share it first to me by email because I have no idea what it looks like :) Posted 7 days ago
