Description:Poria sequoiae Bonar Fig. 115
Jour. Forestry 29:377. 1931 (UC; BPI).
Annual, small to effused, up to 4 mm thick, "difficultly separable" (Bonar), with a faintly resinous taste; margin "thin, closely appressed, 1-2 mm wide" (Bonar); pore surface pale cream, dull, the tubes when dry brittle, up to 4 mm long, pores subround, 3-4 (-6) per mm, edges somewhat thickened, entire; context white, thin, waxy, firm, continuing unchanged into the trama.
Tissue not changing color in KOH; hyphal system somewhat uncertain, probably dimitic, the context hyphae swelling and partially dissolving in KOH, in IKI the skeletal hyphae rarely branched, thin- to thick-walled, nonseptate, mostly 3-6 µm in diameter, generative hyphae fragmentary, sometimes at least often branched, nodose-septate, 2-5 µm, in diameter, and with other (?binding) hyphae very much branched, very irregular and crooked, mostly 2-4 tt in diameter; trama continuous with the context and hyphae almost entirely of the disintegrating type in KOH, "2.5-3.5 µm in diameter" (Bonar) ; hymenium about 12-17 µm thick; cystidia none; basidia slender-clavate, 12-15 x 5-6.5 µm; spores hyaline, smooth, IKI -, oblongellipsoid to ellipsoid, 3-4 (-5) x 1.5-3.5 µm or "4.5-6 x 2-3.5 µm " (Bonar).
On Sequoia tempervirens Endl. in California; associated with a brown pocket rot, see the original account cited above, and Kimmey and Lightle in For. Sci. 1:104-110. 1955, and Kimmey in U. S. D. A. For. Serv. For. Pest Leaflet 25. 1958. Poria cinerascens has been confused with this but it seems to differ in having somewhat longer spores. Additional material and cultures are needed to fix the identity of this species.
