Description:Diagnosis: Can be distinguished from C. congolensis by its more robust stature and frequently fasciculated growth, as well as by its association with Eucalyptus robusta.
Cap up to 15 cm or more, when young very pale, cream to pale yellowish brown or even whitish when remaining covered by dead leaves or other detritus, with appressed, grayish- brownish squamules which become less visible when the cap is expanding, rapidly turning to reddish brown or blackish brown, and finally black. Hymenophore strongly decurrent and well delimited, irregularly and strongly veined-sinuate as well as anastomosing as to almost forming pores, up to 3 mm high, with obtuse edges, pale grayish or isabelline, then turning mouse gray and finally blackish gray to black in an unregular pattern. Stipe short and robust, mostly 20– 30 × 10–20 mm, subcylindrical or slightly narrowing upwards or even ventricose when young, dirty cream or even pure white when young, quickly staining brown or gray and finally blackening with handling or age, smooth, compact and firm. Flesh very firm and thick beneath the cap center, white to whitish with almost some greenish tinges toward the stipe base, rapidly turning to a dirty brownish gray and finally black when cut. Taste mild to even slightly bitter. Smell weak but typical, of apricot. Spore print with distinct yellowish tinges.
Spores ellipsoid, (6)6.5-6.98-7.5(8.1)×(3.7)4-4.35- 4.7(4.8) μm, Q = (1.4)1.5-1.61-1.8(1.9), smooth, filled with one to numerous oily inclusions. Basidia mostly 50-65(74)× 7-8(−9) μm, subcylindrical to weakly clavulate, often sinuate, (3-)5-6-spored; basidiola slender, subcylindrical, sinuate, becoming tardily clavate. Subhymenium filamentous, of slender, strongly septate, hyphal cells, 2-3(4) μm wide like the basidium base. Cystidia none. Pileipellis a loose cutis of ramifying, thin-walled hyphal extremities, measuring mostly 5-8(12) μm diam., terminal cells subcylindrical and hardly differentiated from the subapical ones, but often slightly constricted subterminally and subcapitate, all containing a brown diffuse pigment; no incrusting pigments observed at the surface but present in lower tissues. Clamp connections present everywhere.
