Species Information
Microscopic:
spores 7.8-8.7 x 2.8-3.5 microns, narrowly elliptic or cylindric, "smooth, thin-walled, homogeneous in content, with a small but distinct lateral apiculus"; basidia 4-spored, 18-23 x 2.5-3.5 microns, ovate or nearly spherical when young, elongating into cylindric or subcylindric forms, multiguttulate, basally clamped, with hymenium thickening by basidial proliferation from basal clamp connection, "sterigmata short, easily collapsed, weak"; subhymenial hyphae densely packed, 1.5-2 microns wide, thin-walled, colorless, relatively straight next to the contextual part, but becoming tortuous as subbasidial cells, "producing basidia as side branches and then as branch tips"; contextual hyphae thin-walled, colorless, "generally parallel, loosely arranged, gloeous, uninflated", 1-1.5 microns thick, usually with multiguttulate contents, septa with conspicuous clamp connections throughout, (Petersen), spores 7.5-9.0 x 2.5-3.5 microns (McCune)
Habitat and Range
SIMILAR SPECIES
According to McCune(2), Multiclavula coronilla can be once branched (Peterson(27) just says "simple".) McCune(2) differentiate it from M. sharpii by saying that M. coronilla has fruitbodies that are white to pale yellow (as opposed to tan), and spores measure 5-7.5 x 2.1-3.8 microns.Habitat
gregarious, sometimes crowded, associated in BC with algae or moss protonemata, on clay soil
