The nomenclatural history of Gomphus sensu lato began with Persoon in
1797. Over 200 years species of Gomphus sensu lato have been variously classified
also under Cantharellus, Craterellus, Chloroneuron, Chlorophyllum,
Gloeocantharellus, Nevrophyllum, and Turbinellus.
Species of Gomphus sensu lato have been historically characterized as
having aboveground fruiting, fleshy basidiomata with...
The Demonstration of Ecosystem Management Options (DEMO) study is a large-scale, multi-year, interdisciplinary project examining the effects of various levels and patterns of green-tree retention on multiple forest features. Six retention levels and patterns were examined and replicated across six blocks of predominately Douglas-fir forested land in western Oregon and...
The survival, growth, foliar nutrient status, ectomycorrhiza (EM) colonization,
and associative N-fixation of ponderosa pine seedlings (Pinus ponderosa var. ponderosa
Doug!. ex Laws.) were studied under different gap sizes in forest canopy during the first growing season. Seedling performance variables were assessed relative to gap size of the forest canopy...
Retreating glaciers and the periglacial areas they vacate for organismal colonization produce a harsh environment of extreme radiation, nutrient limitations, and temperature oscillations. They provide a model system for studying mechanisms that drive establishment and early assembly of communities. Here, we synthesize more than twenty years of research at the...
Recent surveys of belowground fungal biodiversity in Mexico and USA have revealed many undescribed truffle species, including many in the genus Tuber. Here we describe seven new species: Tuber beyerlei, T. castilloi, T. guevarai, T. lauryi, T. mexiusanum, T. miquihuanense and T. walkeri. Phylogenetic analyses place these species within the...
Truffles have evolved from epigeous (aboveground) ancestors in nearly every major lineage of fleshy fungi. Because accelerated rates of morphological evolution accompany the transition to the truffle form, closely related epigeous ancestors remain unknown for most truffle lineages. This is the case for the quintessential truffle genus Tuber, which includes...
Gymnomyces is an ectomycorrhizal basidiomycete genus in the family Russulaceae estimated to contain less than 50 species worldwide, with 23 species known to occur in the Pacific Northwest. Gymnomyces species are common in Pacific Northwest forests that include Pseudotsuga, Abies, Tsuga, and Quercus. They produce sequestrate (truffle-like) sporocarps with ornamented...
Six species of Cystangium, a genus of
sequestrate taxa related to Russula, were collected
in Patagonia (Argentina and Chile) during autumn
2001. Two species, C. depauperatum Singer & A.H.
Sm. and C. nothofagi (E. Horak) Trappe, Castellano &
T. Lebel, were already known from this region, while
four new species,...
