ENDOSPORE^E. 
[COMATRICHA. 
apices of the component sporangia; columella brown, slender, 
capillary, aggregated, but for the most part individually free ; 
capillitium loosely interwoven into a common mass ; mass of 
spores brown. 
Hah. On decorticated pines. — Germany. 
This description applies to S. splendens^ y.flaccida ; but without the 
character of the spore-markings, which could not be discerned by the 
older authors, no certain conclusion as to the species can be arrived at. 
7. S. fluminensis Speg., in Ann. Soc, Cient. Argent, xii., p. 255 
(1881). Hypothallus very thin, broadly effused, mucedinous, 
black, rather shining ; stem erect, rather rigid, black, shining, 
0"5 to 1 mm. long, 0-6 to 0*7 mm. thick; smooth when moist, 
rugulose when dry, subcontorted, extending into the sporangium 
as a columella, not reaching to the apex ; sporangium cylindrical, 
rarely subclavate, rounded at both ends, 0'8 to 1"2 mm. long, 
0'2 to 0'3 mm. thick, black, opaque, wall persistent for a long 
time ; capillitium arising from the columella, forming a rather 
dense network, the superficial meshes equal to or twice the 
diameter of the spores, with uncinate incurved tips ; spores 5 to 
8 /A diam., smooth, smoke-brown. 
Hah. On old bark and moss. — Brazil. 
This description applies to a small form of Comatriclia typhoides.

Genus 1 6.— COMATRICHA Preuss, in Linnsea, xxiv,, p. 140 
(1851), Sporangia cylindrical, ovoid or globose, gregarious or 
scattered ; sporangium-wall evanescent (subpersistent in C. 
typhoides), stipitate, the stalk extending within the sporangium as 
a columella for half its length or more, branching above, and 
continued into the crisped or flexuose capillitium, which consists 
of numerous threads rising from all parts of the columella, 
combined into a more or less uniform network, not forming 
a superficial net,
