This plant has been long known in Europe. There is a rather poor figure of it in Schaeffer Table 37, and a better one in Gillet Champignons de France, Hymenomycetes, =1=, opposite page 76, but a very good one in Bresadola Funghi Mangerecci e Velenosi, Tavel 18, 1899. A good figure is also given by Barla, Les Champignons des Alpes--Maritimes, Pl. 19, Figs. 1--6. The plant was first reported from America in the 41st Report, State Museum, N. Y., p. 82, 1888, under the name _Tricholoma peckii_ Howe, from the Catskill Mountains, N. Y. Figure 86 is from plants (No. 3991, C. U. herbarium) collected in the Blue Ridge mountains, at Blowing Rock, N. C., during September, 1899. The European and American description both ascribe a bitter taste to the flesh of the pileus, and it is regarded as suspicious. There does not seem to be a well formed annulus, the veil only being present in a rather young stage, as the inrolled margin of the pileus is unrolling from the surface of the stem. It seems to be more in the form of a universal veil resembling the veil of some of the lepiotas. It shows a relationship with _Tricholoma_ which possesses in typical forms a delicate veil present only in the young stage. Perhaps for this reason it was referred by Howe to _Tricholoma_ as an undescribed species when it was named _T. peckii_. If its affinities should prove to be with _Tricholoma_ rather than with _Armillaria_, it would then be known as _Tricholoma aurantium_. TRICHOLOMA Fr. In the genus _Tricholoma_ the volva and annulus are both wanting, the spores are white, and the gills are attached to the stem, but are more or less strongly notched or sinuate at the stem. Sometimes the notch is very slight. The stem is fleshy-fibrous, attached to the center of the pileus, and is usually short and stout. In some specimens when young there is a slight cobwebby veil which very soon disappears. The genus is a very large one. Some species are said to be poisonous and a few are known to be edible. Peck, 44th Report, N. Y. State Mus., pp. 38--64, describes 46 species. [Illustration: FIGURE 88.--Tricholoma personatum. Section (natural size).] =Tricholoma personatum= Fr. =Edible.=--This plant occurs during the autumn and persists up to the winter months. It grows on the ground in open places and in woods. The stem is short, usually 3--7 cm. long × 1--2 cm. in thickness, and the cap is from 5--10 cm. or more broad. The entire plant often has a lilac or purple tint.
