Cover
The mushroom genus
Gomphus
is represented by four species in the Pacific Northwest.
Gomphus
is placed
in the family Gomphaceae and is typified by often gregarious to ceaspitose habit, gross scales on the cap
surface, and wrinkled hymenium.
Gomphus bonarii
(Morse) Singer, a strategy 3 fungus species from table
C-3 in the record of decision, is presented on the cover. Locally abundant and widespread throughout
northern California, Oregon, and Washington. Photo courtesy of D. Arora.

This handbook is a companion to the
Handbook to Strategy 1 Fungal Species in the Northwest Forest Plan,
Gen. Tech. Rep. PNW-GTR-476, published in October 1999. It includes 73 record-of-decision (ROD)­
listed fungal species not contained in the first handbook, as well as updated site, field, and collecting
forms; an expanded set of artificial keys to all fungal species from both handbooks; and an updated,
partially illustrated glossary. The main purpose of this handbook is to help facilitate the survey, collection,
and handling of potential ROD-listed fungal species by USDA Forest Service and USDI Bureau of Land
Management employees. Each species is represented by a condensed description, a set of distinguishing
features, and information on substrate, habitat, and seasonality. We also present a list of known sites within
the range of the northern spotted owl, a distribution map, and additional references to introduce the avail­
able literature on a particular species.
Keywords: Mycology, mushrooms, sequestrate fungi, truffles, biodiversity, monitoring, rare fungi, forest
ecology.

Introduction
Purpose of This Handbook
This handbook is a companion to the
Handbook to Strategy 1 Fungal Species in the Northwest Forest Plan
PNW-GTR-476 published in October 1999. It includes 73 record-of-decision (ROD)-listed fungal species
not contained in the first handbook, as well as updated site, field, and collecting forms; an expanded set of
artificial keys to all fungal species from both handbooks; and an updated partially illustrated glossary. The
main purpose of this handbook is to help facilitate the survey, collection, and handling of potential ROD-
listed fungal species by USDA Forest Service and USDI Bureau of Land Management employees.
Important Revisions of the ROD That Pertain to Fungi
In January 2001, amendments to the “survey and manage,” protection buffer, and other mitigation mea­
sures, standards, and guidelines were published in which ROD species were placed in categories (A, B, C,
D, E, and F) rather than in the original strategies. Table 1 lists the fungal species, their original ROD strate­
gies, and their new categories. Following is a brief explanation of the categories, excerpted from the above-
mentioned document:
Category A. Rare, predisturbance surveys practical
Species are included in category A when (1) there is a high concern for persistence, (2) the
species occurs rarely or is sparsely distributed within the range of the Northwest Forest Plan,
(3) all known sites or populations are likely to be necessary to provide reasonable assurance
of persistence, and (4) predisturbance surveys are practical. Only one fungus species,
Bridgeoporus nobilissimus,
is placed in category A.
Category B. Rare, predisturbance surveys not practical
Species are included in category B when (1) there is a high concern for persistence, (2) the
species occurs rarely or is sparsely distributed within the range of the Northwest Forest Plan,
(3) all known sites or populations are likely to be necessary to provide reasonable assurance
of persistence, and (4) predisturbance surveys are not practical. The majority of fungi are
placed in category B.
Category C. Uncommon, predisturbance surveys practical
Species are included in category C when (1) there is not a high concern for persistence, (2) it
is likely that not all known sites or populations throughout the species’ range in the North­
west Forest Plan area are necessary for reasonable assurance of persistence, (3) the species is
uncommon, as opposed to rare, and (4) predisturbance surveys are practical. No fungal spe­
cies are placed in category C.
Category D. Uncommon, predisturbance surveys not practical or not necessary
Species are included in category D when (1) there is not a high concern for persistence, (2) it
is likely that not all known sites or populations throughout the species’ range in the North­
west Forest Plan area are necessary for reasonable assurance of persistence, (3) the species is
uncommon, as opposed to rare, and (4) predisturbance surveys are not practical or necessary.
Surveys of habitat across the landscape are likely to be more effective at finding sites needed
for long-term persistence than focusing in areas proposed for projects. Ten species of fungi
are placed in category D.
