Agaricus subrufescens was called the “almond mushroom”

Several preliminary studies have suggested that Agaricus blazei has anti-tumor properties. While the mechanism of action is unclear, Agaricus blazei appears to "switch on" apoptosis (programmed cell death) in certain cancer cells, including those involved in multiple myeloma, leukemia, fibrosarcoma, prostate cancer, ovarian cancer, and lung cancer.

However, the action of agaritine differs from β-glucan which indirectly suppresses the proliferation of tumor cells. Agaritine has been shown to induce adenomas and adenocarcinomas in the lungs of mice when administered through drinking water. It has also been shown to cause bladder cancer in mice. Agaritine has been claimed to be a weak carcinogen, with an estimate for cumulative lifetime risk from mushroom consumption at approximately 1 in 10,000.
