Notes: Found growing in soil/leaf litter, stem base was slightly bulbous and buried. The cap margin curls inward. Smelled slightly of anise. Stained very red, quickly after cutting. No phenol smell.

The new book by book by Parra Sanchez, Fungi Europaei Vol 1a (2009) is the first major and exhaustive work, which takes advantage of molecular methods. A number of well established species have been bundled, such as A. silvaticus and A. haemorrhoidarius. Its a revamp of the book on Agaricus by A. capelli (1984)
Creating species concepts on the basis of just one morphological trait may not be the best approach.
Many species of Agaricus can be described as having a almond-anise odor, different people will sometimes perceive odors differently and some fungi will smell different at different points in their life cycle.
Sov, thanks for the invitation to comment. I do not know the species you found, either from experience or from the literature. I believe that the northwestern USA (plus BC) harbors quite a number of undescribed species.
You may have a relative of ‘A. haemorrhoidarius’ although the anise odor wouldn’t normally be present among that group. The spore size is close to that of several other members of section Sanguinolenti.
The name ‘A. haemorrhoidarius’ is no longer used. It is an OLD name from Europe that was applied to several species there, and mycologists have given up trying to figure out which one was ‘true’ (they use newer, clearer names instead). The name has been applied to several more species in North America, causing predictable confusion. More than 20 related species have been found in North America.
If you find your species again, a good preserved collection would be very useful.
