them. There are a few Hymenogasters that are not hypogeal. The<br />

most frequent, epigeal species we have is Rhizopogon, and in the<br />

South, Hydnangium Ravenelii.<br />

Nothing has been written as to the habits of Hydnangium Ravenelii,<br />

but we judge from the specimens that it grows on the surface<br />

of the ground. There is a statement that when fresh it exudes a<br />

milky fluid when cut. If true, it is one of the few Hymenogasters so<br />

characterized. The surface of the dried plant is smooth with a pinkish<br />

color. The gleba formed of cells, empty to the eye, has a pale pinkish<br />

cast. Collection notes as to habits, color when fresh, color of gleba<br />

when freshly cut, milky juice, if any, etc., are earnestly desired.<br />

Hydnangium Ravenelii was named by Berkeley as a variety of<br />

Hydnangium Stephensii of England. We do not know the latter<br />

plant excepting from description, and Tulasne's figure of the spores.<br />

The spores of the American plant are not the same as Tulasne's spores.<br />

They are globose or slightly compressed when young, and the spines<br />

are more blunt.<br />

We use the word spines as usually applied to the spores of<br />

Hydnangium, but are suspicious that it is a mistake. We think they<br />

do not have spines but are reticulate, the edges of the reticulations<br />

appearing as "spines" as seen under the microscope.<br />

Hydnangium Ravenelii was referred to the genus Octaviania by<br />

Tulasne, as found in Saccardo. The distinction between these two<br />

genera is not obvious to us, and we have studied species of both<br />

genera from Europe. The "cottony" peridium that characterizes<br />

Octaviania according to description is not in evidence in dried specimens.<br />

The trama is the same, and hardly vesicular as attributed to<br />

Hydnangium, nor are the cells of the species "filled with spores."<br />

We believe it would simplify matters to call both Octaviania, as<br />

Vittadini originally did.<br />

Hydnangium Ravenelii seems frequent in the South. We have<br />

specimens from G. C. Fisher, Florida; F. S. Earle, Dr. R. P. Burke,<br />

and A. S. Bertolet, from Alabama.<br />

ANTHURUS MACOWANI (Fig. 779). We reproduce the figure<br />

of this species that was published recently in Marloth's Flora of<br />

South Africa It is quite a rare species and seems to have been<br />

named in honor of the fact that it was never collected by MacOwan.<br />

The genus Anthurus is known now by only two species, Anthurus<br />

aseroeformis (cfr. Syn. Phalloids, fig. 46) in Australia, and this from<br />

South Africa and in addition there is a very imperfectly known<br />

species in India, Anthurus calathiscus (fig. 49, 1. c.) On comparing<br />

the figure published by Dr. Marloth, with that of the Australian<br />

species published in our pamphlet, it will be seen that they closely<br />

approach each other. They differ in shape, but not so much but that<br />

they can be a modification of the same. If the South African species<br />

proves in time to be the same as that of Australia, I presume I am<br />

to blame, for the drawing was submitted and passed on by me before<br />

it was published. At that time, however, we had no illustration of<br />

the Australian species, and only knew it imperfectly. There is an-<br />
