Taxonomy and Biological Classification



Agaricus blazei Murrill belongs to the family Agaricaceae within the order Agaricales. Initially identified in the late 19th century by American mycologist William Alphonso Murrill, it was later reclassified due to its morphological similarities with other Agaricus species. The mushroom possesses a distinctive almond-like aroma, attributed to benzaldehyde compounds, setting it apart from other members of its genus.



Morphological Characteristics



The fruiting body of Agaricus blazei Murrill is characterized by a convex cap that flattens with maturity, reaching up to 12 centimeters in diameter. The gills are free and crowded, transitioning from pinkish-brown in youth to a dark brown upon spore maturation. The stipe, or stem, is sturdy with a single annular ring. The mushroom's spores are ellipsoid and measure approximately 5.5–6.5 by 4–5 micrometers.



Biochemical Composition



Agaricus blazei Murrill is rich in bioactive compounds, including polysaccharides, sterols, and secondary metabolites that contribute to its medicinal properties. The primary polysaccharides of interest are β-glucans, which have been studied for their immunomodulatory effects. Additionally, the presence of ergosterol derivatives and antioxidants like phenolic compounds enhances its therapeutic potential.



Polysaccharides and Immunomodulation



The β-glucans in Agaricus blazei Murrill interact with immune cells through pathogen recognition receptors such as dectin-1 and CR3.
