Description:Carpophores (Figs. 25 to 30, 88 to 98) flabelliform, narrowly attached or, frequently, attenuate at the base and then appearing substipitate, thin and coriaceous when fresh, drying quite rigid, 1.2-3.5 x 1.5-5 x 0.1-0.45 cm, occasionally laterally confluent, coalescing so closely as to appear continuous on upper surface but with separate points of attachment visible from lower surface, the upper surface of young carpophores and margins of mature ones velvety to touch, "moderate reddish orange" (10.0R5/10, 6/10), "vivid orange" (2.5YR6/ 14), "strong orange" (2.5YR6/12, 6/14), and "moderate orange" (2.5YR6/10~, the surface of older specimens smooth, shining, with the appearance of having been seared with a hot iron, usually more reddish orange: "deep red" (7.5YR3/10), "dark red" (7.5R3/8), "moderate reddish orange" (10.OR5/8), "dark reddish orange" (7.5R4/10, 10.0R4/10), and "deep orange" (2.5YR5/10), the surface usually zonate, with alternating zones paler in color and weathered in texture, or the whole surface occasionally faded to gray with only tinges of the original color remaining; the margin acute, fertile almost to edge; the pore surface "strong reddish orange" (7.5R5/12), "deep reddish orange" (7.5R4/12), "moderate reddish orange" (10.OR5/10), "dark reddish orange" (10.0R4/10), "deep orange" (2.5YR5/10), to almost blackish, the pores originating as shallow ridges 1 mm or less from edge, maturing rapidly in narrow zone, 4 to 6 per mm, the dissepiments relatively thick in younger parts, becoming very thin with age.
In section, carpophores 1 to 4.5 mm thick, the tubes 0.5-2 mm long, the context and upper surface continuous and homogeneous, when cut with a sharp scalpel, the alternating bands of white and pinkish orange distinct, separating readily along zone lines; when broken or teased apart the context appearing cottony-floccose, homogeneous; turning black with KOH.
Hyphae of four types make up the carpophores.
(a) Thin-walled, nodose-septate hyphae, the contents homogeneous, hyaline or pale yellow in lactic acid, staining in phloxine, branched and anastomosed, 1.0-3.3 µm diameter, observed in mounts from margin and walls of tubes (Figs. 88, 89). These are "generative hyphae".
(b) Hyphae with walls thin or only slightly thickened, at first staining in phloxine but soon empty and non-staining, aseptate and unbranched over long lengths, frequently coated with orange granules which are persistent in lactic acid but disappear rapidly in KOH, 1.9-4.6 µm diameter, frequent in mounts from margin and upper surface, less frequent in context (Figs. 91, 92, 93).
(c) Hyphae with thin to thick walls which appear layered, suggesting that the thickening is laid down in successive layers and may cease at any stage from slight thickening to complete obliteration of the lumen, rarely branched, with long aseptate, unbranched terminal cells, frequently with bands of orange granules, interwoven hut easily teased apart in the context, compactly bound together by binding hyphae in the transition area at top of tubes, 2.6-6.6 ; diameter, making up most of mounts from context and surface, numerous in mounts from transition zone and walls of tubes (Figs. 90, 94).
(d) Narrow hyphae, 1.9-2.6 µm diameter in the walls of the tubes, up to 4.0 µm diameter in the layer above the tubes, with walls thick or subsolid, frequently branched, the branches usually short, recurved, firmly interlocked with thick-walled hyphae to form the compact tissue of the transition layer between context and tubes, interwoven in the walls of the tubes (Figs. 95, 96). These are "binding hyphae".
Basidia clavate, 4.6-5.2 µm diameter, bearing four spores (Fig. 97); basidiospores hyaline, even, non-amyloid, short-cylindric or ovoid, 4.0-5.2X2.0-2.6 µm (Fig. 98).
