Page number:315 
Remarks (public):Cultures of Daedalea confragosa may fail to develop a definite pseudoparenchymatous layer, in which case the key pattern will be identical with those for Fomes scutellatus and Collybia radicata. In the key, mention is made of the macroscopic appearance of the cultures, but in addition it may be noted that Fomes scutellatus is usually limited to Alnus spp., and that fiber hyphae are lacking in cultures of Collybia radicata and numerous in cultures of the other species. Cultures of Daedalea confragosa that form a pseudoparenchymatous layer key also to Polyporus tuberaster, P. brumalis, and Collybia radicata. Polyporus tuberaster occurs very rarely, being known from Canada from only a few localities in Manitoba and Saskatchewan, and never in association with decay. Cultures of Daedalea confragosa differ from those of Polyporus brumalis in the extent of the colored areas on the surface, and from cultures of Collybia radicata in the presence of fiber hyphae, which are lacking in the latter species.

Description:Daedalea confragosa Bolt. ex Fries
KEY PATTERN: 1 2 1 1 (6,9) 2 2 2 2 2 (1,2)
CULTURES EXAMINED: CANADA. Quebec: Chelsea, on Betula papyrifera, 9210; Meach Lake, on Fagus grandifolia, F1577. Ontario: Constance Bay, on. Betula sp., F5213; Ottawa, on Acer sp., 8997.
Cultural characters: (Pl. I, Fig. 5; Pl- II, Figs. 15 to 17).
Growth characters. Growth moderately rapid, plates covered in three weeks. Advancing zone even, hyaline and appressed in zone 1-2 mm wide. Mat white, with patches of "pinkish, cinnamon" (6.OYR6.5/5 . 5), "cinnamon" (5.OYR5 .8/6.0), and "snuff brown" (7.OYR3. 9/3. 5) (two to three weeks), to "bister" (4.5YR3.0/3.0) (four weeks), the newer growth downy to fine woolly and minutely lacunose, becoming felty to chamoislike, and crustose in colored areas. Reverse unchanged or "snuff brown" (7. OYR3. 9/3. 5) to "antique brown" (8.OYR4.2/2.5) in irregular patches. Odor in some isolates fairly strong at two to three weeks of age, suggesting pepper, disappearing with age. On gallic and tannic acid agars diffusion zones strong, no growth on gallic acid agar, trace to 1.5 cm diameter on tannic acid agar.
Hyphal characters. Advancing zone: hyphae hyaline, nodose-septate, frequently branched, 1.5-3.0 µm diameter. Aerial mycelium: (a) hyphae as in advancing zone; (b) fiber hyphae numerous, with walls thick and refractive, hyaline or yellow in crustose areas, the lumina narrow or apparently lacking, occasionally branched, aseptate, curving and interwoven, 1.5-3.0 µm diameter; (c) hyphae from skinlike areas nodose-septate, with numerous short branches or projections, compactly arranged and interwoven with fiber hyphae to produce pseudoparenchymatous areas. Submerged mycelium: (a) hyphae as in advancing zone, frequently branched; (b) crystals short, needlelike.
Type of rot: white mottled rot of broad-leaved trees.
