and long marginal striations. Long marginal striations indicates that at lease the part of the cap under the striations has rather thin flesh. One key to separating albocreata is that the base of the stem has a universal veil ring around the top of the bulb. That is to say that the volva in albocreata is like the volva typically shown in illustrations for Amanita species such as pantherina, velatipes, and multisquamosa. The volval remnant at the top of the bulb in this material is an irregularly shaped flap. This is more typical of gemmata-like species.

An example, of a species known from Ohio is “sp-S01.”
