Species Information
Summary:
Features include tiny fruitbodies growing on small diameter roots, the colorless fruitbodies consisting of a dry, powdery, fertile head and a bald stem, and microscopic characters.
Microscopic:
spores 2.5-3 microns, nearly round to lens-shaped, appearing smooth under light microscope but roughened under scanning electron microscope, inamyloid, colorless, thin-walled, 1-celled, usually uniseriate in the ascus; asci normally clustered on a common subhymenial cell, 8-spored, 19-22 x 3-3.5 microns, cylindric, "undifferentiated apically, evanescent", "occasionally formed in chains of 2, or as intercalary units at the bases of the capillitium hyphae"; capillitium hyphae interspersed among the asci, projecting well above the intact asci, 50-100 x 3.5-4 microns, contorted, colorless, thin-walled, septate; stem composed of filaments to only slightly inflated cells, 3-5.5 microns in diameter, with smooth, slightly to notably thickened walls (up to 0.5 microns), "somewhat incrusted in the apical region"
Notes:
Collections were examined from BC and WV (Redhead).

underground on small diameter roots
