_Paxillus rhodoxanthus_ seems also to be very near if not identical with _Clitocybe pelletieri_ Lev. (Gillet, Hymenomycetes =1=: 170), and Schroeter (Cohn's Krypt, Flora Schlesien, =3=, 1: 516, 1889) transfers this species to _Paxillus_ as _Paxillus pelletieri_. He is followed by Hennings, who under the same section of the genus, lists _P. flavidus_ Berk., from N. A. The figure of _Clitocybe pelletieri_ in Gillet Hymenomycetes, etc., resembles our plant very closely, and Saccardo (Syll. Fung. =5=: 192) says that it has the aspect of _Boletus subtomentosus,_ a remark similar to the one made by de Schweinitz in the original description of _Agaricus rhodoxanthus_. _Flammula paradoxa_ Kalch. (Fung. Hung. Tab. XVII, Fig. 1) seems to be the same plant, as well as _F. tammii_ Fr., with which Patouillard (Tab. Anal. N. 354) places _F. paradoxa_ and _Clitocybe pelletieri_. =Paxillus atro=tomentosus= (Batsch) Fr.--This plant is not very common. It is often of quite large size, 6--15 cm. high, and the cap 5--10 cm. broad, the stem very short or sometimes long, from 1--2.5 cm. in thickness. The plant is quite easily recognized by the stout and black hairy stem, and the dark brown or blackish, irregular and sometimes lateral cap, with the margin incurved. It grows on wood, logs, stumps, etc., during late summer and autumn. [Illustration: FIGURE 161.--Paxillus atro-tomentosus, form hirsutus. Cap and stem brownish or blackish (natural size, small specimens, they are often larger). Copyright.] The =pileus= is convex, expanded, sometimes somewhat depressed, lateral, irregular, or sometimes with the stem nearly in the center, brownish or blackish, dry, sometimes with a brownish or blackish tomentum on the surface. The margin is inrolled and later incurved. The flesh is white, and the plant is tough. The =gills= are adnate, often decurrent on the stem, and easily separable from the pileus, forked at the base and sometimes reticulate, forming pores. =Spores= yellowish, oval, 4--6 × 3--4 µ. Stevenson says that the gills do not form pores like those of P. involutus, but Fig. 161 (No. 3362 C. U. herbarium) from plants collected at Ithaca, shows them well. There is, as it seems, some variation in this respect. The =stem= is solid, tough and elastic, curved or straight, covered with a dense black tomentum, sometimes with violet shades. On drying the plant becomes quite hard, and the gills blackish olive.
