    CONTENTS: A fully referenced overview of the Oregon Mycological Society's ground-breaking study conducted entirely by volunteers, the first in North America to establish permanent experimental and control plots to compare the impact of sporocarp removal upon subsequent fruiting. Provides a background on possible causes for decline in mushroom productivity in America and overseas (pollution, habitat destruction, over-harvesting), details the experiment site, project design and protocols, and offers the first preliminary conclusions inferred from three years baseline and six years of harvesting data. These data suggest: (i) no statistically significant correlation between sporocarp removal and productivity, (ii) an outcome not influenced by harvesting method (pulling versus cutting); (iii) a significantly positive correlation between chanterelle abundance and average summer temperature; and (iv) no correlation between chanterelle abundance and precipitation. The author also notes that the chanterelle being studied probably represents the endemic Cantharellus formosus and not C. cibarius. [Ten-year harvesting data now imply that chanterelle removal may stimulate future chanterelle abundance, see Norvell & Roger, 1998, above. (See also Projects: Chanterelles)]

    Omphalina sensu lato in North America 4: 0. rosella. Mycologia 87(6): 880-885.
    ABSTRACT: The invalid combination Omphalina rosella is validated. A new variety, O. rosella var. vinacea, is described from western North America. It is illustrated and compared to O. rosella var. rosella from Europe and North Africa, and an unnamed variety from Baja California, Mexico. Omphalina rosella is an anomalous species intermediate between Omphalina and Rickenella. Also included: New records (WA), complete nomenclator, and discussion of generic placement.

    Systematics of PNW Phaeocollybia species: molecular and morphological collusion. Abstract in Inoculum 46(3): 32.

    ABSTRACT: DNA has been extracted and amplified from the ITS1 & ITS2 regions associated with the 5.8S rDNA gene from 130 PNW and extralimital collections of Phaeocollybia (Agaricales, Cortinariaceae). Informative polymorphisms have been generated from nine different restriction enzymes (Cfo1, EcoR1, Hinf1, Nde2, Pal1, Pvu2, Rsa1, Sal1, Xho1), and compared with the morphological and ecological characters of 25 putative species. The molecular data appear to support species hypotheses generated from the more traditional morphological analyses. Phaeocollybia scatesiae has been revealed as synonymous with P. californica [this synonymy is no longer recognized] while four new species are supported as molecularly and morphologically distinct from other PNW species. RFLP generated groupings of collections with the P. kauffmanii complex appear to be linked to subtle anatomical and microscopical differences. Chemical, developmental, and ecological investigations of 600 Phaeocollybia collections made in British Columbia, Washington, Oregon, and California (1991-1994) continue to reveal the unique biology of the genus and its integral place in the old-growth Pacific coast mesic forest ecosystem.

    Strategy 1: Phaeocollybia, Herbaria, and the Perception of Rarity. Abstract in Program: Oregon Native Plant Society Symposium on Conservation and Management of Native Habitat. Corvallis, Oregon.
    ABSTRACT: Phaeocollybia is an easily recognized genus of mushrooms flagged by the Forest Ecosystem management Assessment Team (FEMAT) in 1993 as closely associated with old-growth coniferous forests. With 60 species reported worldwide, the genus reaches its greatest diversity in the PNW with at least 23 species endemic to the Northern spotted owl forests from northern California to British Columbia. These mushrooms have long been considered rare, with neither distribution nor fruiting patterns well documented. The author's intensive sampling of phaeocollybias and evaluation of herbaria collections of Strategy-1 species (Record of Decision, 1994) have revealed the dangers of defining fungal rarity based on herbarium records alone. Striking and distinctive fungal species genuinely rare in the field appear to be disproportionately represented in herbaria, while common nondescript macrofungi are under-represented. Unfortunately, determination of fungal rarity is complicated by the fact that macrofungi -- in fact microorganisms requiring microscopic examination for accurate identification -- produce fruiting bodies that are typically short-lived and unpredictable in their emergence. Additionally, numbers of fruiting bodies present on a given site may indicate only a prolific single organism rather than species [abundance]. Thus basing the perception of rarity on relative numbers of herbarium collections can be both misleading and erroneous. (See also Projects: Phaeocollybia, Northwest Forest Plan; Biodiversity)

    CONTENTS: Where the author ruminates over the difficulties of differentiating Phaeocollybia species in view of conflicting morphological and molecular data. "I spent the whole day describing, chemically testing and microexamining your carefully wrapped specimens of Phaeocollybias spadicea, oregonensis, piceae, fallax, lilacifolia, kauffmanii, benzokauffmanii, and "cryptokauffmanii" - all of which I can recognize and all of which I can't tell you why…" (See also Projects: Phaeocollybia, Agaric Taxonomy and Nomenclature)

    ABSTRACT: Omphalina cyanophylla and Mycena lilacifolia are considered to be synonymous. A new genus Chromosera is described to accommodate C. cyanophylla. North American specimens are described. Variation in the dextrinoid reaction of the trama is discussed as is the circumscription of the genus Mycena. Peculiar pigment corpuscles are illustrated. ALSO INCLUDED: North American distribution (BC, MB, NB, NS, ON, PQ, CA, MI, NY, OR, TN, WA). (See also Projects: Agaric Taxonomy and Nomenclature)

    The Chanterelle (Cantharellus cibarius) -- A Peek at Productivity. IN Proceedings: The Business and Science of Special Forest Products -- A Conference and Exposition January 26-27, 1994. Chris Schnepf, ed. Western Forestry and Conservation Association, Portland, OR. pp. 117-128.
    ABSTRACT: Since 1986 the Oregon Cantharellus Study Project team has been engaged in long-term research of the chanterelle, a commercially harvested edible mushroom associated with economically significant timber species in the Pacific Northwest. Eight years ago Oregon Mycological Society members established 10 plots in a 100 year old hemlock-Douglas-fir stand in the buffer zone of Mt Hood's Bull Run watershed to study whether harvesting chanterelles adversely affects later fruitings. All chanterelles have been numbered, flagged, measured, and mapped every 2 weeks throughout the growing season. Since 1989 all chanterelles over 1 cm in diameter have been removed from 6 of the 10 plots, either by cutting (3 plots) or by pulling (3 pots). No chanterelles have been removed from the 4 control plots. while data reveal a wide fluctuation of overall productivity -- indicated by biomass as well as numbers of fruiting bodies -- from year to year, harvesting data fail to show that picking chanterelles has an impact on the subsequent productivity over the short term. Factors that may influence productivity include canopy cover, short and long term weather patterns, and the presence of coarse woody debris. (See also Projects: Chanterelles)]
