The English name for Agaricus bisporus is "white button mushroom". Unfortunately I don't have access to the full article, but the link from the paper leads to an abstract that describes this study as a survey of 17 other papers: https://academic.oup.com/advances/advance-article-abstract/doi/10.1093/advances/nmab015/6174025?redirectedFrom=fulltext https://academic.oup.com/advances/advance-article-abstract/d... So likely they're not all based on US consumption of US-common varieties, but I do wish I could find more details.
