Description : 213. Polyporus Curtisii, Berk. MSS.
Pileo excentrico molli-suberoso sulcato zonato ochroleuco hic illic sanguineo-laccato. Stipite elongato, rugoso, sanguineo-laccato. Hymenio ex albo ochraceo; poris punctiformibus. Curt., No. 549, 577, 908, 979, 1131, 1525.
Pileus 3-6 inches across, excentric, convex, more or less grooved and zoned, of a rather soft corky texture, covered with an ochraceous, often opake, laccate crust, which is in parts sanguineous. Substance towards the tubes cinnamon, above ochraceous, not zoned, traversed with laccate lines parallel to the surface. Margin obtuse.
Stem 2-5 inches high, 0.5-1 inch thick, rough, sanguineo-laccate.
Hymenium white, here and there ochraceous, often partially laccate. Pores punctiform, not angular, cinnamon coloured, within stratose.
This splendid species is closely allied to Polyporus lucidus, but differs in its beautiful pale ochre-yellow tint, its punctiform pores, and in its substance not being zoned. The true Polyporus lucidus occurs in the same district, retaining exactly the character of European specimens. There is also some resemblance, especially in the punctiform pores, to Polyporus ochreolaccatus, Mont., but the habit and whole appearance of the two species is very different.
seems to be a significant diagnostic macro feature.
that all observations labeled G. curtisii so far are centrally stipitate to laterally stipitate with varnish only developing in older specimens and that all specimens have been observed growing at ground level.
