Phosphate transporter genes as reliable gene markers for the identification and discrimination of arbuscular mycorrhizal fungi in the genus glomus.

An inorganic phosphate transporter gene sequence (852-bp section) allowed discrimination between 10 Glomus fungal species represented by 25 strains. It was particularly valuable in differentiating between morphologically similar species with nucleotide and amino acid sequence differences higher than 3%. This gene is proposed as a reliable barcode for the Glomeromycetes.

Morchella tomentosa: a unique belowground structure and a new clade of morels.

Mechanisms involved in post-fire morel fructification remain unclear. A new undescribed belowground vegetative structure of Morchella tomentosa in a burned boreal forest was investigated north of Fairbanks, Alaska. The name "radiscisclerotium" is proposed to define this peculiar and elaborate below-ground vegetative structure of M.

A fungal endophyte of black spruce (Picea mariana) needles is also an aquatic hyphomycete.

An aquatic hyphomycete, Dwayaangam sp., was isolated from superficially sterilized black spruce (Picea mariana) needles submerged in aerated water in a small glass chamber (microcosm). The internal transcribed spacer (ITS) sequence of this fungus and of a commonly encountered foliar endophyte isolated from P.

Lophodermium macci sp. nov., a new species on senesced foliage of five-needle pines.

The new species Lophodermium macci is described. It is similar in its morphology, habitat, geographic range and ecology to L. pini-excelsae, L.
