but must constitute a new genus, which exactly illustrates
the difference between Licea and Lindbladia or Tubulina
respectively; whereas the only distinction given by Rostafinski
between Tubulina and Lindbladia amounts to saying that in the
former the sporangia are elongated; in the latter, shorter.
A well-defined hypothallus is often present, and in some
species, as T. stipitata, B. and C., forms an elongated, stem-like
structure which possibly consists of sterile, modified sporangia.
Dr. Geo. A. Rex has kindly furnished me with a sequence of
specimens, all belonging to Tubulina cylindrica as defined in the
present work, which to my mind show clearly the transition
from Tubulina to Siphoptychium, and thus furnishing a connecting
link between the Peritrieheae and the Oolumelliferae.

A. Sporangia, regular or plasmodiocarp.
Tubulina minima, Mass.
Sporangia scattered, sessile on a broad base, hemispherical or
variously elongated, little depressed; wall thin, smooth; from clear
to obscure brown; torn above into severalyigreisigjii, irregular teeth;
mass of spores umber, spores globose, minutely warted, 10—12 g
diameter.

(Specimen from Fries in Herb. Berk.)
Britain (Bulmer, Yorks).
On pine wood and sawdust. Germany ; Sweden ; Finland.
An obscure species, which, from its scattered habit, is easily
overlooked; when circular from ’5—1 mm. across; frequently
2—3 mm. when elongated. The colour varies from almost chestnut
to blackish brown; ruptured above in an irregularly stellate
manner.
The inner surface of wall of sporangium has numerous
coloured cells or masses arranged in groups.
Rostafinski’s gratuitous suggestion that the present species
is a Phelonitis is altogether wrong.
Tubulina flexuosa, Mass.
Sporangia scattered, sessile on a broad base, circidar or variously
elongated and flexuous, wall thin, single, shining; deep olive or
tinged with brown; mass of spores olive; spores globose, pale
olive-brown, minutely warted, the warts showing a tendency to
form very short ridges, 12—15 g diameter.

On decaying wood, especially pine. Britain (Aboyne, N. B.);

From 1—1’5 mm. when circular, often 2—3 mm. when
elongated. The wall of the sporangium is furnished inside with
a layer of fine granules of organic matter.
