o the peculiar way in which it is formed.

Some of the stages of development are illustrated in Figs. 64--67. The
buttons are queer looking objects, the bulb being the most prominent
part. It tapers abruptly below, and on the upper side is the small
rounded young cap seated in the center. The volva is present as a rough
floccose layer, covering the upper part of the bulb and the young cap.
As the stem elongates and the pileus enlarges and expands, the volva is
torn into areolate patches. The lower patches, those adjoining the
margin of the cap and the upper part of the bulb, are separated in a
more or less concentric manner. One or more of them lie on the upper
part of the bulb, forming the "limb" of the "ocreate" volva. Others lie
around the margin of the pileus. Sometimes an annular one bordering the
pileus and bulb is left clinging part way up on the stem, as shown in
Fig. 66. The concentric arrangement on the pileus is sometimes shown for
a considerable time, as in Fig. 67, the elongated areas being present in
greater number at this age of the pileus. However, as the pileus expands
more, these are separated into smaller areas and their connection with
the surface of the pileus becomes less firm.

The formation of the veil and annulus can be easily followed in these
figures. The margin of the cap in the button stage is firmly connected
with the outer layer of the stem at its lower end. This probably occurs
by the intermingling growth of the threads from the lower end of the
stem and the margin of the cap, while the edges of the gills are quite
free from the stem. Now as the stem elongates and the cap expands the
veil is "ripped" up from the outer part of the stem. This is very
clearly shown in Fig. 66, especially where two strips on the stem have
become disconnected from the margin of the cap and are therefore left in
position on the outside of the stem.

This species is related to _A. excelsa_ Fr., which is said to have a
superior ring.
