C. rachodes is similar to C. brunneum, but has a double ring with one ridge sloping up and the other down, and the base of the stipe that is swollen, or a bulb with a sloping top (no ridge)  However, care is needed not to confuse these with the similar species C. molybdites, which has a green spore print. Although it's not known in New Zealand, it does need to be confirmed if poisoning is to be avoided.
