cordyceps
Cordyceps militaris is an edible fungus that forms small orange clubs on parasitized insects. It grows from buried larvae and pupae, with records from forests in the State of Mexico. Researchers study its compounds and possible effects on immune markers and exercise performance.[2][3][7][9][11]
Edible. Eat it cooked. Never eat a wild mushroom identified only from photos.

These findings describe research. None of them is a recommendation to use it. If you take medication or have a disease, talk to your doctor.
Where and when does scarlet caterpillar club grow?
It parasitizes insect larvae and pupae, primarily butterflies and moths. In the State of Mexico, researchers documented it on Paradirphia lasiocampina in oak-pine forests and secondary oak vegetation.[2][3]
Documented collections span July through October in the State of Mexico. These dates apply to the study sites.[3]
