Stemonitis typhoides, Auct.
Stemonitis maxima, Sz.
Sporangia crowded, stipitate, springing from a well-developed
hypothallus; sporangia cylindrical; wall blackish, reflectino-
metallic tints, evanescent; columella reaching almost to the
apex of the sporangium; capillitium dense, branches often
arcuate, sometimes more or less irregularly dilated, especially
at the nodes, peripheral meshes much larger than the diameter
of the spores; mass of spores hlaclcish hroton; spores globose
vei-y minutely verruculose, 5—10 g diameter; stem filiform’
black, shining, shorter than the sporangium.

Cuba; United States; Australia; Cape of Good Hope.
A fine large species, distinguished amongst the dark-spored
species by the large peripheral meshes of the capillitium.
Lumps of organic matter are sometimes met with in considerable
quantities on the threads of the capillitium; 1 '5 - 3 cm
high.
Stemonitis typhina, Mass.
Gregarious, but not usually crowded, springing from a delicate
hypothallus; sporangia cylindrical, obtuse at both ends, wall
very thin, brownish, disappearing; columella reaching to the
apex, capillitium dense, threads originating a t numerous points
from the columella, dingy brown, copiously branched and forming
a dense, irregular network, thickest at the point of origin
and tapering towards the periphery where they are very slend°er,
and form a network of irregular pattern, with the meshes usually
not larger than the diameter of the spm-es; stem erect, slender,
cylindrical, usually rather shorter than the sporangium, blackish;

mass of spores brovmisli-black, lilac-brown by transmitted light,
globose, very minutely asperate, 5—8 g diameter.
Rostafinski gives the following forms, hut it is not unusual
to meet with both in the same cluster.
a. Genuina.—Sporangium with stem 2^—4 mm. high.
/3. Pumila.—Sporangium with stem 2 mm, high.

From 4—7 mm. high. Closely allied to G. pulehella, but
distinguished by the dark brown colour of the spores in the
