Species Information

Summary:
Features include tiny fruitbodies growing on fine rootlets, the colorless fruitbodies consisting of a dry, powdery, fertile head and a bald stem, and microscopic characters.
Microscopic:
spores 7-9.5 x 5.5-6 microns, nearly round to broadly elliptic, 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 cell, 8-spored, 31-53 x 6.3-7 microns, cylindric, "undifferentiated apically, evanescent", occasionally formed in short 1-celled to 3-celled chains that disarticulate easily, or in intercalary fashion as basal cells to the capillitium hyphae; capillitium hyphae "interspersed among the asci, projecting well above the intact asci", 100-230 x 4.5-5 microns, contorted, colorless, thin-walled, septate, occasionally branched at the bases, and occasionally slightly swollen in upper part; stem composed of slightly inflated cells, 3.5-7(9) microns in diameter, with smooth, slightly thickened walls forming textura porrecta tissue
Notes:
Collections were examined from BC (Redhead).

Habitat and Range

SIMILAR SPECIES
Roeslerina microspora has smaller fruitbodies, spores, and asci, and may have different habitat on larger perennial rootlets 0.5-1cm thick versus the smaller primary rootlets 0.05-0.1cm thick for R. radicella, (Redhead).
Habitat
underground on fine rootlets
