154 BRAZILIAN MOSSES. 
Moist rocks, Corcovado, z. 4, (1). 
30. Leptostomum ? pusillum, n. sp. Caule breviusculo, fo- 
liis imbricatis erectis ovato-lanceolatis acutis, nervo subcon- 
tinuo, capsula clavato-pyriformi nutante, operculo hemi- 
spheerico-apiculato brevi. 
Summit of the Organ Mountains. 
About one fourth of an inch high, and not unlike a small 
state of Bryum polymorphum, Br. and Sch., but the peristome 
wholly absent, and the inflorescence bisexual. In habit, this 
moss belongs to Bryum, but has also some resemblance to 
Mielichoferia. An annulus is present. 
31. Bryum acuminatum? Bruch, and Sch. Bryol. Europ.—var. 
peristomio interno ciliis instructo. Summit of the Organ 
Mountains. 
32. Brachymenium Hornschuchianum, Hornsch. in Fl. Bras. 
Organ Mountains, on the trunk of an old tree. March, 
1837. b, at the summit of the mountains, n. 25, (2). 
33. Rhizogonium eruginosum, nov. sp. Caulibus simplicibus 
fasciculatis compressiusculis, foliis oblongo-lanceolatis nervo 
excurrente (perichetialibus ovatis acuminatis nervatis), 
capsula subcylindrica erecta, operculo capieaceg bata in- 
curviusculo. 
On the stem of a tree-fern, Organ Mountains, n. 3, (2). 
Stems half-an-inch high, or more, crowded, bearing the 
fructification at the base. Leaves of a light verdigris green; 
sub-erect, slightly denticulate at the apex, papillose, reticula- 
tion minutely granular. Perichztial leaves reddish, erect and 
appressed. Seta shorter than the stems. Capsules, when old, 
wide-mouthed. Operculum nearly as long. Calyptra dimi- 
diate. 
The specimens are not in a state to show the peristome, if 
there be any, in this moss. The foliage, as in Schistostega, is 
not easily wetted. 
34, Bryum argenteum, Linn. 
Rio Comprido, n. 19, (1).
