Species Information
Summary: Features include 1) resupinate growth on barkless, rotten hardwood, 2) a watery grayish color often with tint of pink or lilac, 3) waxy consistency, 4) spores that are allantoid, smooth, inamyloid, and colorless, 5) basidia that are more or less constricted, sometimes the basidia developing inside old basidia (internal basidial repetition), 6) absent cystidia, and 7) a monomitic hyphal system, the hyphae with clamp connections.
Galzinia incrustans has been found in BC, ID, ON, PQ, IA, LA, MA, MD, ME, MN, MO, NY, WI, and VT, (Ginns), and Sweden and Norway, (Eriksson). The distribution includes Europe including Switzerland and Asia, (Breitenbach).
Fruiting body: resupinate, thin, mainly about 0.005cm thick; "watery grayish, often with a tint of rose or violaceous"; smooth, ceraceous [waxy] when fresh and wet, pruinose when dry; margin indeterminate [indistinct], (Eriksson), resupinate, "forming inconspicuous isolated spots or continuous thin patches several centimeters across", tightly attached, waxy, soft; gray-ocherish with lilac to pink tint; uneven, slightly undulating-tuberculate, ocher-farinose; margin indistinctly farinose [mealy], (Breitenbach), spore deposit white (Buczacki)
Microscopic: SPORES 4.5-6 x 1.5-2.5 microns, allantoid, smooth, inamyloid; BASIDIA 4-spored, 15-20 x 4-5 microns, subcylindric, more or less constricted, internal basidial repetition observed in a few basidia; CYSTIDIA "normally none, but thinwalled, projecting cystidia-like organs are found in one specimen"; HYPHAE monomitic 2.5-3.5 microns wide, walls thin or somewhat thickened, richly branched, clamp connections at all septa, (Eriksson), SPORES 5.5-7 x 2-3 microns, cylindric, curved, smooth, inamyloid, colorless; BASIDIA 4-spored, 17-27 x 3-4.5 microns, cylindric-clavate, young basidia develop in some of the old, mostly somewhat collapsed basidia (internal repetition), best observed under phase contrast; CYSTIDIA not seen; HYPHAE monomitic: hyphae 2-3 microns wide, septa with clamp connections, (Breitenbach)
