Amanita rhopalopus

Common Name - American Club-Footed Lepidella

Synonyms:

Substrate: Ground

Location: Hardwood Forests

Spore Color: White

Gill Color: White to Pale Cream

Comments: 

Lepidellas are a large group of Amanitas that are often difficult to distinguish. That being said, they are some of the most impressive mushrooms that can be found in our area. Many can commonly grow to be over a foot tall.  If you plan to attempt an ID, it is always helpful to dig up any potential root along with the mushroom.

Several things that distingush this mushroom from other Lepidellas. The first is that the warts on the cap are not often clearly defined as some other species. They also do not have fibers emanating from them onto the cap. (Check with a hand lens). There should be a bulb at the base which is enlarged. Dig down and try to get the entire root with your collection. The bulb should have a dogleg in it, changing directions off to one side as it goes into the ground, although this is not always the case.

As with all Amanitas: free gills and white spores, growing from the ground. 

Somewhat strong smell of chlorine or decaying protein. Some say old ham or old tennis shoes. 

Lookalikes:  

Amanita ravenelii has small fibers that emanate from the warts on the cap. Amanita daucipes has a large turnip shaped basal bulb, that is often vertically split. It usually has some slightly pinkish floccose material on stem that can rub off, especially when young, and pinkish tones to the cap. Also possibe pinkish remnants of a volva that have fallen above the bulb at the base of the stem or onto the ground.   Amanita polypyramis has a pure white cap with concentric rings of pyramidal warts around the bulb. Amanita cokeri has a persistent annulus, lacks reddish bruising, and lacks a strong odor.
