You're comparing raw mushrooms to cooked, lean beef and appear to have cherry picked the lower protein common variety of tofu (instead of the higher protein calcium set variety which is equally common or much more common where I live). If I use similarly misleading choices from the same dataset I could 'support' beef being lower protein than tofu by comparing cooked calcium set tofu to raw fatty mince. Or similarly, dried mushrooms would only require 600g or so (whilst also covering most of your energy needs). At 4-6ish % by mass when cooked, mushrooms are decent, but not really higher than most plant sources. Great source of many micronutrients though and complement tofu/beans well.
