How to use The Boletes of California

This is an online reprint of California Mushrooms: A Field Guide to the Boletes by Dr. Harry D. Thiers. This version (The Boletes of California) adds some online features not available on the printed page. This page explains how to use those features and gives you a tour of this site's organization.

Navigating the Pages

Several navigational aids help you move through the pages.

The Navigation Frame

If your browser supports frames (as all recent browsers do), you should see a frame at the bottom of the page.  The frame contains navigation controls to help you move through the site's pages:

If your browser doesn't support frames, use the browser's Back and Forward buttons to get back to the main page and find other pages as necessary.

Finding the Content You Want

We've segmented the contents of The Boletes of California into separate web  pages for this site and we've added a few new pages such as this one to support the book in its online form.  These are the main segments.

New Online Content

This material is new content written for the online version of The Boletes of California.

Introductory Material

These pages from the original book introduce you to the book and to boletes in general.

Taxa Descriptions

These pages are the heart of the original book, and describe boletes at different levels of classification.

Additional Material

The original book also included these additional sections:

Using the Keys

To identify boletes to species, you must learn to successfully use either of the two keys offered here: the technical key or the field key.  Each key is presented on its own page.  You'll find at the top of each page a list of links to different parts of the key, typically links to genus, section, or subsection.  If you've identified a specimen already to genus, section, or subsection, just click on the appropriate classification and start working through the key at that point until you find the species you think is appropriate.  If you don't know your bolete's genus, section, or subsection, click on the top link to start at the beginning of the key.

If you haven't used a dichotomous key before, you'll find that it consists of a series of two-statement pairs: couplets.  To work through the key from your starting point, find the statement in the first couplet that best describes your specimen, and look at the link or number to the right of that statement.  If it's a link, click on it to jump to the next part of the key and continue work from there--or, if you've identified it to species, to jump to the species description.  If you see a number, read down in the current key to the couplet with that number and continue to work through the key from there.

Working through a key requires that you know the terminology and characteristics used to describe boletes.  If you don't know them, you can learn them in the page About Boletes.  If you're stymied by a word you don't find there, you may find it in the glossary of Fungi of the Bay Area.

Reading Species Descriptions

Each species description page contains the original description written by Dr. Thiers.  You'll find the species name, citation, and synonyms. You'll also find microscopic and macroscopic characteristics, notes on habit, habitat, and distribution, and observations.  If there's a photo of this species in the microfiche, you'll find a link to that photo at the top of the page.

We've added a few small elements for the online version of this book at the bottom of the page.  If we know about an online photo or description of the species described, you'll find a link to the photo or description here.  In a few instances, if we know of some taxonomic changes that have taken place since this book was published, we'll note them here.
