A commercial scale biochar field trial was established on a farm in Québec, Canada in May 2008. A very fine, commercially available biochar from fast pyrolysis of wood waste was applied as received from the manufacturer using standard farm machinery. The target application rate was 5.6 t/ha, but an estimated 30% of the material was wind-blown and lost during handling, transport to the field, so...

Background and Purpose: Mycorrhizal fungi are of high importance for functioning of forest ecosystems and they could be used as indicators of environmental stress. The aim of this research was to analyze ectomycorrhizal community structure and to determine root colonization rate with ectomycorrhizal, arbuscular mycorrhizal and endophytic fungi of poplars growing on pyrite tailings contaminated ...

Suillus quiescens sp. nov. is common under Pinus muricata on Santa Cruz and Santa Rosa Islands in the northern Channel Islands of California, and we subsequently found it fruiting at Point Reyes National Seashore on the central coast of California. Sequences from the internal transcribed spacer region show that it is distinct from all 44 species of Suillus tested, and features of its morphology...

At germination, container-grown shortleaf pine seedlings were inoculated with Pisolithus tinctorius (Pers.) Coker & Couch or left uninoculated, and both groups were fertilized semiweekly with a modified Hoagland's solution supplemented with 0 or 0.4 mM boric acid. After 12, 16 and 24 weeks, seedling root tissue was analyzed for ectomycorrhizal colonization, phenolic concentration and phenoloxid...

The Family Russulaceae comprises of some important agaricoid and gasteroid taxa of Agaricomycetes. Two genera, Lactarius and Russula are distinctive basidiomycetes that possesses heteromerous tissue composed of sphaerocyte cells and amyloid ornamentation on their basidiospores. Some of the important ectomycorrhizal, edible, poisonous and medicinal species have been rested in genera Lactarius an...

Mycorrhizae are obligate fungi that predominate in the roots and soil of higher plants. They form association with plant roots in a host-non specific manner. Seven types of mycorrhizae have been known i.e. arbuscular, ecto, arbutoid, ectendo, ericoid, monotropoid and orchidaceous mycorrhizae. Out of these, arbuscular and ectomycorrhizae are the most abundant and wide spread. They promote plant ...
