Species Information
Summary: Features include 1) resupinate growth on wood, 2) a pinkish buff to buff fruitbody with a granulose to colliculose surface, the margin pale and radiate-fibrillose, 3) spores that are lobed, irregular, irregularly round, or nearly round, echinulate, and pale brown, 4) basidia with red contents in water mount, and with transverse septa, and 5) hyphae with clamp connections. According to rules of Latin and Latinization, "coerulea" should be corrected to "caerulea", but this is not done here because the change would affect the first syllable: "The liberty of correcting a name is to be used with reserve, especially if the change affects the first syllable and, above all, the first letter of the name.", Article 60.3 International Code of Botanical Nomenclature (St. Louis Code).
