- ABSTRACT: Investigation of Phaeocollybia in British
Columbia, Washington, Oregon, and California has led to a
better understanding of the characters and biology of the
genus as a whole. Generically significant characters - pseudorhizas,
pellicular veil, tibiiform diverticula, and sarcodimitic tissues
- are examined in depth with four variations of branched and
unbranched pseudorhizal patterns outlined. Basidiome development
is traced from subterrancean initiation to fully mature emergent
basidiomes. Hypotheses on the ontogeny of Phaeocollybia
basidiomes and biological associations are developed based
on extensive observations of primordia and numerous field
excavations. Comparisons between rhizomorphs and the thread-like
pseudorhizal extensions of certain species are made and the
term "rhizomorphic pseudorhiza" is introduced. Possible biological
strategies are explored and evidence for consideration of
Phaeocollybia as a mycorrhizal genus is presented.

Chanterelle preliminary observations and productivity data
(1986-1997). Abstract in Inoculum 49(2): 40.
- ABSTRACT: Cantharellus formosus (the Pacific Golden
Chanterelle) is the principal choice edible ectomycorrhizal
chanterelle commercially harvested from Pacific Northwest
(British Columbia, Washington, Oregon, and California) coastal
forest. In 1986 the Oregon Mycological Society initiated North
America's longest continuous investigation into the impact
of harvesting on subsequent productivity. A total of ten individual
plots (in three replicate blocks) were established in a 120
year old Tsuga-Pseudotsuga stand in the buffer zone
of Portland's Bull Run watershed in Mt Hood National Forest.
Within the plots 292 species of fungi (123 mycorrhizal, 106
terricolous saprophytes, 56 lignicolous saprophytes and parasites,
7 fungal parasites) have been recorded. Since 1986 volunteer
researchers have tracked 5471 chanterelles (individually numbered,
flagged, measured and mapped) every two weeks from July to
December. Beginning in 1989 all chanterelles over 1 cm in
diameter have been removed by cutting (3 plots) or pulling
(3 plots), weighed before and after drying to determine biomass
and retained for future molecular analysis; the remaining
four non-harvest plots are monitored as controls. Nine years
of harvesting data indicate that removal of chanterelles may
slightly stimulate subsequent chanterelle productivity (measured
both as numbers of basidiomes and as biomass) in the short
term. A statistically significant positive correlation between
mean summer temperatures and numbers of chanterelles is suggested,
but there appears to be little to no correlation between productivity
and harvesting method. Other observations include the relatively
slow growth rate (e.g., expansion of the pileus diameter at
a rate of 2-5 cm/month) and long life span with fruiting bodies
observed in situ for as long as 90 days. Factors that
may influence productivity include canopy cover, short and
long term weather patterns, and the presence of coarse woody
debris. The internationally recognized study demonstrates
how collaboration between professionals and amateurs (who
have together thus far generously donated nearly 5000 hours
of labor) can contribute significant and valuable scientific
knowledge. (See also Projects: Chanterelles)

ABSTRACT: Investigation of the agaric genus Phaeocollybia
(Cortinariaceae) in British Columbia, Washington, Oregon
and California has resulted in a revised taxonomic revision
of the genus in the Pacific Northwest and led to a better
understanding of the characters and biology of the genus
as a whole. Generically significant characters - pseudorhizae,
pellicular veil, tibiiform diverticula, and sarcodimitic
tissues - are examined in depth with four variations of
branched and unbranched pseudorhizal patterns outlined.
Basidiome development is traced from subterranean initiation
to fully mature emergent basidiomes. Hypotheses on the monovelangiocarpic
development of Phaeocollybia basidiomes are developed
based on extensive observations of primordia and numerous
field excavations. Comparisons between rhizomorphs and the
thread-like pseudorhizal extensions of certain species are
made and the term 'rhizomorphic pseudorhiza' is introduced.
Possible biological strategies are explored and evidence
for consideration of Phaeocollybia as a mycorrhizal
genus is presented.
Morphological characters obtained from specimen examination
and molecular characters generated from PCR amplification
and single restriction enzyme digestion by 9 restriction
enzymes of ribosomal DNA were subjected to computer-assisted
phenetic and phylogenetic analyses. Analytical results support
recognition of several new species not previously described
from this region and imply separation of other species judged
as conspecific by earlier workers. Analyses of data from
P. kauffmanii and four associated new species within
a species complex demonstrate the importance of incorporating
molecular data and computer analyses in modern taxonomic
research. Preliminary analyses of 25 putative taxa suggest
that sections proposed by previous investigators are probably
polyphyletic. Problems encountered using restriction fragment
length polymorphisms derived from differently sized amplified
regions in phylogenetic analyses are also briefly discussed.
A conspectus of the Pacific Northwest species is accompanied
by an emended generic description, discussion of placement
of Phaeocollybia within the Cortinariaceae, and dichotomous
and synoptic keys to all 25 currently recognized taxa. Full
technical descriptions of nine new species (P. ammiratii,
P. benzokauffmanii, P. luteosquamulosa, P. phaeogaleroides,
P. pleurocystidiata, P. redheadii, P. rifflipes, P. rufotubulina,
and P. tibiikauffmanii) accompany emended descriptions
of sixteen previously described taxa. Phaeocollybia
carmanahensis is synonymized with P. oregonensis.
Phaeocollybia deceptiva is excluded from the genus.
