Summary:
Features include 1) resupinate growth on hardwoods, 2) a fruitbody that becomes cream and pinkish buff to wood-brown in the herbarium, more or less colliculose, with broad, slightly elevated granules, the margin narrow, fibrillose, sometimes radiate, 3) spores that are 8-12 x 5-8 microns, smooth, and colorless, and 4) hyphae 2-3 microns wide, mixed with mineral material, somewhat longitudinally interwoven and then ascending to a compact hymenium. According to Hjortstam (1989) quoted by J. Ginns, the type "is obviously an extreme form of the familiar and variable Radulomyces confluens" (Ginns(5), Latin name italicized).
Radulomyces cremoricolor has been found in BC, NS, AL, CA, DC, FL, IL, IN, MA, MD, MI, MN, MO, NJ, NM, MY, OH, PA, TX, and WI, (Ginns(5)).
Fruiting body:
2-10cm long, 1.5-3cm wide, often confluent, broadly effused [spread out], "rather thick, membranaceous, small pieces separable when moistened", in section 0.02-0.08cm thick; becoming cream and pinkish buff to wood-brown in the herbarium; cracking into areolae 0.2-0.3cm across "and with a distinct radial arrangement of the principal cracks frequently", more or less colliculose with broad, slightly elevated granules; "the margin narrow, fibrillose, sometimes radiate", (Burt)
Microscopic:
SPORES 8-12 x 5-8 microns, flattened on one side, smooth, colorless; no gloeocystidia; HYPHAE 2-3 microns wide, rarely wider, "not incrusted but mixed with more or less mineral matter", "somewhat longitudinally interwoven and then ascending to a compact hymenium"; section not colored, (Burt)
