tagne's herbarium, from Leprieur, French Guiana. It does not follow,
however, that it is such a rare plant, but only that the plants of the
region have been scantily collected. Our figure is a photograph of the
types.

CAMILLEA TURBINATA (Figs. 830-833).--Plants obconic or turbinate, about
a cm. tall and broad, growing in a dense cluster from a common, mycelial
carbonous base. The summit is truncate, and marked with a raised central
disc, which is thin and in old plants breaks irregularly. A section of a
young plant (Figs. 831 x6) shows the lower part composed of rather soft,
carbonous tissue, the upper filled with a light brown powder, composed
of spores mixed with hyphae tissue. In old plants the tops break in, the
powder is dissipated, and there remains (Fig. 833) a bundle of carbonous
tubes, the walls of the perithecia. Finally, these break up and
disappear, leaving the upper part of the plant hollow. The spores are
elliptical, 6-7 x 16-18 mic., smooth, light colored. The asci which
disappear at at very early stage, are shown by Moeller as oval, each
containing 8 spores.

This is at common plant in our American tropics, and was named by
Berkeley, as Hypoxylon turbinatum, but in a later paper he referred it
to Camillea turbinata. It is compiled in Saccardo as Hypoxylon. I doubt
not but that it was named Sphaeria caelata by Fries many years "prior."
Spegazzini found it abundantly, and noting that it was not a good
Hypoxylon, puzzled over it in two or three papers and finally also
concluded that it was at Camillea. Moeller also "discovered" it, and
although the common plant was well known in other centers, the rumors
had not reached Berlin, hence he "discovered" it was a new genus, which
he dedicated to his friend, Dr. Hennings and called it Henningsinia
durissima. Fortunately, he gave a good figure by which his "discovery"
could be interpreted.

We have beautiful specimens from Dr. J. Dutra, Brazil, from which our
figure was made, also we have specimens from Rev. Rick.
