Hispidin is a natural substance. It can also be synthesized.^[1]

Hispidin 4-O-β-D-glucopyranoside can be found in Pteris ensiformis^[2] whereas hispidin derivatives, such as phellibaumins, can be found in the edible mushroom Inonotus xeranticus^[3] or Phellinus.^[4]^[5] Hispidin is a precursor of fungal luciferin, a compound responsible for light emission by luminous mushrooms.
