being always erect. Lady Arden favoured me with a specimen of a curious variety, with the skin of the pileus cracked into dquares, leaving white reticulations between.
I cannot help suspecting that the following four species of Dr. Withering will, on mature examination, prove varieties of that now before us, viz. Umbracuhem, p. 289, agreflis, ibid. gracilis p. 313, and splendens p. 334.—For the 1st fee his reference to Batsch, t. 4. The 2d seems to describe imperfect specimens gathered late in the season and in wet weather. The third expresses the state of its maturity in fine weather; and the 4th as I have found it when the gluten is dried up after a dewy morning. In the early part of the season, about August, I have observed a thick gluten on the pileus at 7 in the morning, changed by 11 into a varnish, quite resplendent in the fun, the heat of which hastening the progress of the fungus to maturity, the gills become reddish, and the feeds are found, as Dr. Withering describes them, at their edges. Many Agarics, especially the parasitic ones, are disposed to have long roots. I have found that of A. radicatus 12 inches in length, and Mr. Relhan sent a still longer specmien to the Linnaean Society.

Found in the crevices of stumps of trees, and other damp places, growing in all directions. At first it might be taken for a group of small insects' eggs, being white and nearly sessile, but it is of the consistence of cream. It next acquires a crimson hue, with a partial skin, which separates at length, disclosing a woolly texture replete with fine powder.

The progress of growth in this species is similar to the last; but the long form of its head, and the continuation of the stalk through its woolly substance, are sufficient marks of distinction.
