The last time I took mushrooms was about a year ago, when I was not yet to the point I am at now regarding psychedelic come-ups, and even a low dose caused more anxiety during the come-up than I've felt in a long time. These days I'm finding myself not very prone at all to anxiety, from come-ups or any other source. In my opinion it is almost entirely psychosomatic, but very difficult to avoid until you've become very accustomed to the transition between sobriety and psychedelia.
That being said, I do think that mushrooms are the psychedelic that I've experienced with the greatest tendency to cause anxiety. I think it's a combination of the very fast and mentally intense come-up into one of the most profoundly altered (IMO) mind states available, along with the intense physical buzz that they produce. I've noticed over the years that anxiety generally manifests itself physically around the solar plexus area, and when a person feels that kind of nervous energy there, it's associated with anxiety.
Anyway, mushrooms were the first psychedelic I tried and also the only one for a good two years, and back then, they made me so anxious on the come-up that I was pretty terrified of them. Still today, they're the psychedelic that makes me the most nervous, and I definitely take them very seriously, which is why I hardly ever use them despite them being my most revered psychedelic. Fortunately, I've found that if you hold your head up above the initial anxiety, once you pass the peak, the anxiety dissipates entirely, leaving you in a very pleasurable, enjoyable, and uninhibited state.

It's not the actual drug that gives me anxiety ... my first shroom trip was 100% anxiety free. It was only when I learned how confusing and disorienting a mushroom trip could be that it started giving me some pre-trip anxiety
Interesting observation. Come to think of it, my first trip (which was on mushrooms) was totally anxiety-free as well, and a full-on +4, total spiritual revelation, the likes of which I've never encountered again. It was only after that that I began feeling anxiety from them.
In any case, once you get past the psychosomatic baggage, mushrooms provide one of the most holy and joyful experiences and vibes that I've ever encountered. But that come-up can be rough and takes a lot of willpower to overcome.
