often forming patches 6—9 cm. long and broad; the hypothallus
although thin, is tongh, and can he peeled off the matrix.
Sporangia about 5 mm. diameter and not quite so h ig h ; before
dehiscence yellowish olive and resembling a crowded Perichaena.
Tubulina speciosa, Speg.
Sporangia densely gregarious, fasiculate, fascicles subcircular,
1—2 cm. long and broad, 1— mm. high, seated on a slightly
convex hypothallus; sporangia cylindrical, apices rounded,
dehiscing irregularly, at first flesh-eolour then cinnabar, shining ;
spores warted, rusty-oohre; depressed, dry concavo-convex, with
a thiokish margin.

I have had no opportunity of examining the present species,
the spores of which are described as concavo-convex when
dry, hut in all probability become spherical when moist.
Tubulina stipitata, Rost.
Hypothallus stem-like, often snlcate, spongy within; sporangia
crowded in a suh-glohose head, cylindrical, apices
rounded; walls very thin, evanescent; mass of spores brownish-
umber ; spores globose, 4—5 g diameter, abend three-fonrths of
the surface with a regular small nehuorh, the remainder with
much larger meshes. Rost., Mon,, p. 223, £ 2; Cooke, Myx. Brit.,
f. 2; Sacc., Syll, 7, n. 1392.

On dead wood, bark, &c. Stem 2—4 mm. thick and high,
umber, porous within ; sporangia 1'5—2 mm. long. The spores
are globose when thoroughly soaked.
Dr, G. A. Rex of Philadelphia has recently sent specimens
of the present species having the hypothallus very much
reduced, and also informs me that sessile forms are not uncommon,
hence the specific distinction between T. cylindrica
and the present species turns mostly on spore differences.

Tubulina guaranitica, Roumeg.
Gregarious; sporangia globose, sometimes slightly attenuated
below on passing into the stem; wall single, thin; dingy
oohraceous with a tinge of olive, sometimes greyish below,
about 1 mm. diameter; stem rather thick, slightly incrassated
downwards, and passing into a hypothallus, 1'5—2 mm. long,
ochraceous-hrown; mass of spores umber; spores globose, smooth,
7—8 g diameter.

On decayed bark. Guarapi; Argentine Republic.
With the general appearance of a small specimen of Tubulina
stipitata, differing in having only a single sporangium, or
aethalium surrounded by a thin, friable cortex. The dimorphic
capillitium described by Spegazzini as consisting of septate
threads is clearly nothing more than the mycelium of some
minute fungus spreading in the mass of spores. The tail-like
appendages to the spores mentioned by the author are to be
explained in the same way. The above description is drawn
up from the specimens in Roumeguere’s exsicc. These specimens
were supplied by Balansa, and may therefore he considered
as authentic, inasmuch as Spegazziui’s Fiongi guaranitica
is an account of the Fungi collected by Balansa.
P. Aethalium naked.
Tubulina cylindrica, Rost, (f 1—6).
Sporangia usually crowded and forming a naked cake-like
brown aethalium, rarely scattered, seated on a well-developed
flat or slightly convex hypothallus, cylindrical or subangular
from mutual pressure, more or less elongated, apex rounded;
wall single, thin, often iridescent; mass of spores brownish-
umher; spores globose, about threefourths of the surface loith
a regular, fine-meshed network, the remainder with scattered
ridges and warts, 7—9 g diameter. Rost., Mon., p. 220;
