More than 100 mushrooms in the genus Tricholoma have been reported in North America. Most are relatively large, showy mushrooms that grow on the ground near many species of temperate forest trees, both hardwoods and conifers. They typically fruit from late summer through early winter or even into spring in warmer areas. Some are fine edibles, including the matsutake. Others are inedible or even poisonous. Filling the gap between technical publications and the limited representation of Tricholomas in general mushroom field guides, this book is the first comprehensive guide to North American Tricholomas. It contains more than 170 of the best documentary photographs available, often with more than one image of a species to illustrate the dramatic variation exhibited by many Tricholomas. The species descriptions provide extensive identification information including scientific and common names, macroscopic and microscopic features, occurrence/habit, edibility, and a comment section that addresses such things as synonomy, comparisons with similar species, varietial differences, explanations of species' epithets, and other useful or interesting information. In addition, the authors provide a general introduction to Tricholomas that discusses identification features, ecology, simple chemical tests (for identification), and how to use the keys provided in this book.

Approximately 75 percent of all fungi that have been described to date belong to the phylum Ascomycota. They are usually referred to as Ascomycetes and are commonly found and collected by mushroom enthusiasts. Ascomycetes exhibit a remarkable range of biodiversity, are beautiful and visually complex, and some, including morels and truffles, are highly prized for their edibility. Many play significant roles in plant ecology because of the mycorrhizal associations that they form. Thus it is remarkable that no book dedicated to describing and illustrating the North American Ascomycetes has been published in over sixty years. Filling the gap between technical publications and the limited representation of Ascomycetes in general mushroom field guides, Ascomycete Fungi of North America is a scientifically accurate work dedicated to this significant group of fungi. Because it is impossible to describe and illustrate the tens of thousands of species that occur in North America, the authors focus on species found in the continental United States and Canada that are large enough to be readily noticeable to mycologists, naturalists, photographers, and mushroom hunters. They provide 843 color photographs and more than 600 described species, many of which are illustrated in color for the first time. While emphasizing macroscopic field identification characteristics for a general audience, the authors also include microscopic and other advanced information useful to students and professional mycologists. In addition, a color key to the species described in this book offers a visual guide to assist in the identification process.
