Type Locality: Lake Quinault, WA
Technical Description: Morphological habit Sequestrate Fruiting
body rounded with a vestigial stem and columella. 3-10 x 4-17 mm,
glabrous to pitted. Peridum papery but not separating, light to deep
reddish brown, peridum meeting the basal protrusion leaving a gap of 5
mm exposing underlying locules. Odor mild when fresh and strong
resembling that of Lociarias camphorates or of maple syrup when dried..
Gleba chambered, near cinnamon-buff, the chambers empty and more or
less elongated vertically, lined with pale orange yellow spore deposit,
seperating slightly from the columella. Semi-exposed gills, producing a
white unchanging latex in most fresh specimans Colulmella present and
colored like the peridium, precurrent and unbranched. Basidiospores 810.5 x 7.5-9.5 µm, ellipsoid, globose to subglobose, with amyloid
reticulation. Pale, yellow orange spore print. Basidia 1-4 spored Cystidia
scattered, obtuse apex and sometimes not seen. Other Laticiferous
hyphae, clamp connections absent. Hymenium Context of interwoven
hyaline thin-walled non-gelatinous hyphae with only an occasional
Sphaerocyst and these not grouped into nests. Clamp connections
absent.
Life History: Mycorrhizal Fruiting spring (March-July) and fall
(September-November)
Range, Distribution and Abundance: This fungi is known only from a
portion of the NWFP area in Oregon, from approximately 20 sites.

FS/BLM lands in Oregon and Washington: Rogue River-Siskiyou NF,
Siuslaw NF, Coos Bay BLM and Salem BLM.
Habitat Associations: Occurs principally in soil and litter in western
hemlock, tan oak, live oak, sugar pine, Douglas fir, Pacific madrone,
California black oak, Port Orford cedar and Sitka spruce series at
elevations of 3-3385 (1847) feet of primarily moist forest types. It is
known to be associated with the roots of Douglas fir and western
hemlock and sometimes Pacific madrone, and incense cedar. Other
woody associates include Acer circinatum, Berberis nervosa and
Vaccinium ovatum.
Threats: Actions that disturb soil or remove overstory hosts are the
most serious threats, particularly damage to host trees and disturbance
of soil occupied by host tree roots. Activites such as logging that removes
its presumed mycorrhizal host and other actions that cause disturbance
to the soil, particularly road, trail, and campground construction.
Actions that Logging activities could have impacts on mycorrhizae formed
with associated trees and appears to have been extirpated from some
sites that were clear cut, however, Luoma, 2000 indicated green tree
retention was important for sustainability of this species within forest
management practices at these sites. Wildfire may also adversely affect
populations.
Conservation Considerations: Maintain dominance of specific host tree
associates which are necessary for mycorrhizal association. Minimize
loss, disruption or compaction of soil particularly from management,
road construction, or recreational activities. As a mycorrhizal species,
Arcangeliella camphorata forms symbiotic associations with the fine root
systems of plants, growing out into the soil matrix. Consider
incorporation of patch retention areas (as described in Standards and
Guidelines 1994, C-41) with occupied sites wherever possible.
