From the mushroom species Tricholoma populinum LANGE which shows interesting pharmaceutical effects the steroid 5α,8α‐epidioxyergosta‐6,22‐dien‐3β‐ol has been isolated. The acetate of this compound crystallizes in the monoclinic space group P 2 1 with two molecules in the unit cell of dimensions a = 19.788, b = 7.241, c = 9.914 Å, β = 103,97°. The final R ‐value is 0.079 for 1082 reflections.
