Remarks (internal):LLOYD mistook Umemura 174 for Hydnum amicum (1916, Lett. 63: 9, 14), and Yasuda 361 for Hydnum albo-niger (1916, Lett. 63:9).
ITO (1955:180) recorded the species for his country under the generic name Calodon, but instead of drawing his (Japanese) redescription from the indigenous collection, he faithfully copied Atkinson's data, thus avoiding possible control.
It would seem appropriate to range under the present species a collection from New Guinea for want of a better place:
The material, although very poor, is well dried; it consists of three contorted bits, two of which show small pilei. Pileus up to 20 x 8 mm, ligulate, radiately rugose, rough and dull near the base, smoother and shiny towards the margin, (dark grey-brown) black-brown at the base, (isabella) dingy ochraceous at the margin, (yellowish brown) dark fulvous to tawny in between, without colour zones but mottled with a few collapsed and blackened patches. Stipe apparently none, the pileus springing laterally from an ochraceous to orange-brown, cottony basal pad which encloses bits of decayed wood and soil. Spines immature, up to 0.7 mm long, 0.2 mm thick, blunt, white. Context up to 3 mm thick, indistinctly duplex in the pileus, very clearly so in the basal pad, dingy white to isabella near the margin, passing into grey-brown to warm brown farther back, conspicuously zoned with dark lines, staining olivaceous in KOH. Odour of fenugreek when dry.
Context of pileus monomitic. Generative hyphae 3.6-5.8 µm wide, not inflating, thin-walled, branched, septate, without clamp-connections. Basidia 4-spored, without clamp at the base. Spores (taken from a greyish patch on the underside of the pileus) 4.9-5.2 x 3.6-4.2 µm (measured without spinulae), broadly ellipsoid, spinulose, colourless, with oblique apiculus.
The colours mentioned between brackets are those noted by the collector. The attempt at identifying a collection from New Guinea with a species thus far only known from the southeastern part of the United States is apt to raise the strongest doubts, but the following facts should be considered.
(i) Phellodon putidus, as appears from the foregoing, is also known to occur in Japan. (ii) It is stated (COKER & BEERS, 1951:25) to be a species of deciduous and mixed woods, which is borne out by the find of the New Guinea material in Lithocarpus-Castanopsis forest. (iii) Although the spores of the material from New Guinea are rather larger than those of the Japanese specimen (3.6-4.5 x 3.1-3.5 µm) or of the type (4-4.7 x 3.3-4 µm), it should be pointed out that the difference is most probably due to difference in age, neither the Japanese specimen nor the type being anywhere mature when they were collected. It is significant that L. R. Hesler 12382, cited by COKER & BEERS (1951:26), and compared by me with the type, has the spores 4.5-5.4 x 3-3.8 µm (measured without spinulae).
In the surface and the colour pattern of the pileus the New Guinea collection resembles P. plicatus, but differs from it in the thicker and conspicuously zoned context, in the presence of a thick basal pad, and in the somewhat larger spores.

Description:PHELLODON PUTIDUS (Atk.) Banker-Figs. 41-43
Pileus up to 55 mm across, irregularly orbicular, lobed (or perhaps made up of two confluent pilei), plano-convex to depressed in centre, slightly colliculose-uneven and locally finely wrinkled (probably owing to drying), otherwise smooth, tomentose and dingy cream at the margin, matted or glabrescent and yellowish grey-brown towards the centre, not zoned or with a fairly broad, incomplete, and vaguely delimited darker zone, somewhat shiny; margin thick, reflexed in places. Stipe 15-25 x 6-13 mm, single or confluent, stout, ventricose, tomentose, then matted with a shiny surface, hence seemingly glabrous, cottony at the base, dingy orange-brown to fulvous. Spines up to 2 mm long, somewhat decurrent, crowded, subulate, dingy yellowish, the older ones with a slight greyish tint. Context up to about 3 mm thick in the centre of the pileus, not clearly duplex, but soft and tomentose above, gradually passing into firmer flesh below, yellowish grey-brown; context in the stipe conspicuously duplex, the core being darker than and of a different colour from the tomentum.
Context of the pileus monomitic. Generative hyphae up to 5.4 µm wide, not inflating, thin-walled to slightly thicker-walled, branched, septate, without clamp-connections. Basidia about 27 x 6-7 µm, clavate, without basal clamp, 4-spored, with sterigmata 2.7-3.6 µm long. Spores 3.6-4.5 x 3.1-3.5 µm (measured without spinulae), subglobose, spinulose (spinulae up to 0.9 µm long), colourless, with oblique apiculus.
