[8] The fungus was once thought to be exclusive to South Korea and Japan, but recent discoveries have been made in Indonesia, Papua New Guinea and Australia.

The phialides are arranged in tufts with narrow angles at the top, similar to the branching hyphae found in Trichoderma species.

The conidia are roughly spherical with a truncate base in each spore, pale green in color, and measure 2.5–3.5 μm in diameter.

Symptoms associated with consumption in these cases included stomach pains, changes in perception, decrease in the number of leukocytes and thrombocytes, peeling skin on the face, hair loss, and shrinking of the cerebellum, resulting in speech impediment and problems with voluntary movement.

[15] More recent research out of South Korea shows that the principal human toxicant made by the fungus (at least when grown on culture plates) is satratoxin H.[16]
