Figure [146] is from plants (No. 3295, C. U. herbarium) collected on the Ithaca flats from a willow trunk, Oct. 10, 1899.
Pholiota aurivella Batsch, which has been found in the United States, is closely related to P. adiposa.
Pholiota squarrosa Müll., widely distributed and common in the autumn, both in Europe and America, on stumps and trunks, is a large, clustered, scaly plant, the scales "squarrose", and abundant over the pileus and on the stem below the annulus. It is brownish or ferruginous in color.
Pholiota squarrosoides Pk., as its name indicates, is closely related to P. squarrosa. It has erect, pointed, persistent scales, especially when young, and has a similar habit to squarrosa, but differs chiefly in the pileus being viscid, while that of P. squarrosa is dry. P. subsquarrosa Fr., occurring in Europe, and also closely related to P. squarrosa, is viscid, the scales are closely appressed to the surface of the cap, while in squarrosa they are prominent and revolute.
Pholiota cerasina Pk., occurs on decaying trunks of trees during late summer. The plants grow in tufts. They are 5–12 cm. high, the caps 5–10 cm. in diameter, and the stems 4–8 mm. in thickness. The pileus is smooth, watery when damp, cinnamon in color when fresh, becoming yellowish in drying, and the flesh is yellowish. The stem is solid, and equal, the apex mealy. The annulus is not persistent, and the gills are crowded and notched. The spores are elliptical, and rugose, 5 × 8 µ.
