Dive into the fascinating world of tooth fungi, where the genera Hydnellum and Sarcodon reveal a story of scientific reclassification, unique biochemistry, and practical applications. Modern DNA sequencing studies have reshaped our understanding of these stipitate hydnoid mushrooms, showing that traditional features like texture are often unreliable for identification, leading to the movement of many Sarcodon species into Hydnellum.

Beyond taxonomy, these fungi produce rare p-terphenyl compounds, exemplified in species like Hydnellum caeruleum, with remarkable antioxidant and pigment properties. Artisans have long harnessed species such as Hydnellum aurantiacum to create vibrant natural green and blue dyes, the color shifting based on water alkalinity and pH. From molecular phylogenetics to artisanal crafts, this episode explores how tooth fungi bridge science and traditional usage, revealing the ecological and cultural significance of these overlooked forest mushrooms.
