Taxonomic History and Identification

The story of Agaricus subrufescens begins with its first description by the American mycologist Charles Horton Peck. Identified in the late 19th century, this mushroom was originally described from regions in the Northeastern United States and Canada. Over the years, it has been referred to by several names and has often been confused with other species within the Agaricus genus. However, Agaricus subrufescens maintains taxonomic priority as the oldest name, solidifying its place in mycological records.

Richard Kerrigan undertook genetic and interfertility testing, which played a crucial role in distinguishing Agaricus subrufescens from other similar species. These tests found European samples called, previously referred to by different names, were indeed the same species originally described in North America. This revelation has helped clarify the taxonomy of this remarkable mushroom, ensuring that it is correctly identified and classified in scientific literature.

Differentiating from Similar Species

One of the challenges in mycology is accurately identifying species that share similar characteristics. Taxonomy agaricus subrufescens is no exception, often being mistaken for other Agaricus species such as Agaricus hondensis and Agaricus augustus. The latter, known as “the prince,” is primarily found on the west coast and features distinctive stem decorations that set it apart. Despite these similarities, careful observation of specific traits can aid in accurate identification.

Agaricus species comparison:

• Agaricus subrufescens prefers disturbed ground.
• Agaricus nanaugustus typically grows near spruce trees.
• Agaricus moelleri (inky mushroom) resembles Agaricus subrufescens but has a distinctly different odor and appearance.

Observing these subtle differences helps enthusiasts and mycologists accurately identify this valuable mushroom.

Habitat and Distribution

Agaricus subrufescens is native to North America, where it is commonly found growing in large clusters within leaf litter and nutrient-rich soil.
