Microscopic:
spores 7.5-10.5 x 4.5-5.5 microns according to Donk, (but including other authors, limits extend to 4-15 x 2-8 microns), elliptic or ovoid, smooth, white; basidia 4-spored, 20-28 x 5-6 microns according to Donk, (but including other authors, limits extend to 15-40 x 3-8 microns); hyphae 3.5-6 microns wide, thin-walled, with clamp connections, "with a few gloeocystidium-like hyphae, more or less agglutinated throughout the hymenium", "incrusted with crystals in the subhymenium and sparsely on the stem"; medulla of sclerotia "wholly agglutinated, often filamentous in center, hollow in large sclerotia", cuticle 8 microns thick, golden to reddish brown, (Corner); spores 7.4-9.6 x 2.6-3.6 microns, (Bruehl(1), who says these measurements are smaller than for other workers), spores 8-11 x 4-4.5 microns, elliptic, smooth, weakly amyloid; hyphal system monomitic, (Buczacki)
Habitat and Range
SIMILAR SPECIES
Typhula phacorrhiza does not have a distinct head, and is yellowish in color. Typhula idahoensis and T. ishikariensis have a different color of the fruitbody and sclerotium. None of these species are characterized by the occasional digital or radiate cells in the rind of the sclerotium that are found in T. incarnata if several fragments are examined.Habitat
on dead culms and leaves of cereals and grasses, and on herbaceous stems and leaves, often parasitic on cereals: sclerotia in spring, fruitbodies in fall, (Corner), rarely attacks species other than winter cereals and grasses, but can attack roots and basal crown tissues even in the absence of conditions required for typical snow mold development (prolonged snow cover), (Bruehl(1))
