Astreus Hygrometricus -

Astraeus hygrometricus , commonly known as the "barometer earthstar," is a fascinating gasteroid fungus recognized for its unique hygroscopic movement. Historically valued by tribal communities in South and Southeast Asia for its edibility and medicinal properties, recent scientific inquiry has begun to validate its diverse biological activities. This paper synthesizes current knowledge on its taxonomy, ecology as an ectomycorrhizal partner, nutritional composition, and emerging pharmacological applications, including its antioxidant, anti-inflammatory, and potential anticancer properties. 1. Introduction

Astraeus hygrometricus (Pers.) Morgan is a member of the Diplocystidiaceae or Astraeaceae family. It is widely distributed across tropical, subtropical, and temperate regions, often found in symbiotic association with several tree species. Known colloquially as "puttu," "rugra," or the "hygroscopic earthstar," it has long been a seasonal delicacy and a traditional remedy for various ailments among indigenous populations in India, Nepal, and Thailand. 2.
