Lepiota eriophora

Common Name: None

Synonyms:

Substrate: Ground

Location: Forest

Spore Color: White

Gill Color: White

Comments: 

This is an impressive little Lepiota. This name could be applied correctly, but I do not have the references to verify that this is the best available name. The best name to apply would be Lepiota sect. Echinatae - because the pileus is covered with squamules. This page will be updated as more information is available.

Looking at the second picture, this species can exude reddish droplets on the stem and margin of the cap. 

This name came from comments on L. aspera in North American Mushrooms (Miller).
Based on microscopic features: Spores 4-4.5 × 2-2.5. Dextrinoid. 

Not edible. Potentially poisonous.

Lookalikes:

There are several very similar species floating around. Lepiota aspera has larger spores (6-9 microns) and a less scaly stem. Lepiota asperula has small spores (3-5 microns), also without scales on the stem. What I would call L. asperula.

There are also several other species that can have scaly stems - L. hystrix L. perplexa, and L. echinacea that are included in this group as well.

L. hystrix has larger spores (5.5-7x2.5-3) and seemingly finer and darker, almost black squamules. It is also said to have darker gill edges. May exude blackish droplets.

L. echinacea has small spores (4-5.5x2.5-3.5) and has very variable scales - from fine to pyramidal. May not be able to separate it based on macromorphology. 

I do not have a description of L. perplexa, and it may be limited to Europe as I find no North American observations.
