Species Information
Summary:
Features include 1) thin growth spread out on wood, 2) a yellowish, smooth to folded spore-bearing surface, the margin whitish, sometimes with hyphal strands, the context cottony or granulose, 3) broadly elliptic spores that are smooth, dextrinoid, pale yellow, and cyanophilic, with thickened walls, 4) context hyphae with clamp connections and encrusted with scattered cross-shaped or dentate crystals.
Microscopic:
SPORES 4.4-6.0 x 3.2-4.4 microns, broadly elliptic to broadly oval, adaxially somewhat flattened, smooth, dextrinoid or occasionally only weakly so, pale yellow, cyanophilic, wall thickened, apiculus relatively broad and blunt; BASIDIA 4-spored, (17)20-28 x 5-7(8) microns, narrowly clavate, sterigmata 4.5 microns long; cystidia lacking, CYSTIDIOLES not notable, occasionally with elongated, branched apices; TRAMAL HYPHAE "somewhat woven, not gelatinized"; CONTEXT HYPHAE 2.5-5(6.5) microns wide, distinct, "loosely woven, flexuous", colorless, thin-walled, with clamp connections, often branched at a clamp connection, "incrusted with distinctive but scattered, stauroid to dentate crystals", up to 6 microns in diameter; HYPHAL STRANDS scattered to rare, 15(60) microns wide, composed of one or a few broad (up to 9 microns wide) core hyphae that are surrounded by a number of narrower (up to 3.5 microns wide) hyphae, (Ginns(15))
Notes:
Collections were examined from BC, ID, NS, ON, PE, PQ, ME, MT, NC, NH, NM, NY, SD, VT, WI, Estonia, Finland, Norway, Sweden, and Russia, (Ginns(15)), It has also been recorded from AZ and MI, (Ginns(5)), and MB, YT, and AK, (Thorn(6)).
Habitat and Range
SIMILAR SPECIES
Leucogyrophana mollusca and L. sororia have a spore-bearing surface that is "shiny, tough, and brittle", whereas in L. romellii it is "typically dry, dull, fragile, and crustose"; furthermore, L. mollusca further has large spores, and L. sororia has 1) narrower spores, 2) a translucent spore-bearing surface, and 3) a lack of roughened, stauroid crystals in the context, (Ginns(15)). Leucogyrophana lichenicola is a similar species that has been described from NT, ON, PQ - it differs in being lichenicolous (undersides of hyphal mats of Stereocaulon and Cladonia), in producing brightly colored (pale yellow to bright orange) sclerotia, and in certain culture characters (Thorn(6)).

associated with a brown rot of the wood of Abies (fir), Picea (spruce), Pinus (pine), Pseudotsuga (Douglas-fir), Tsuga (hemlock), one specimen on Betula (birch), (Ginns(15)), rarely also on live mosses (Ginns(5))
