fornia, as well as by Mr. Coville's plant No. 336, collected Feb. 20, 1891, on the 
Death Valley Expedition, in the canyon of Mesquite Spring, in the Funeral 
Mountains west of the settlement of Amargoza, southern California. Coville's 
plant was named by the late Charlec R. Barnes, and was by me reported as Grim- 
mia plagiopodia pilifera L. & J. 
The recent collection was made by Mr. George L. Moxley, on Big Rock Creek, 
vSan Gabriel Mountains, Califo/nia, and was communicated to the writer by Dr. 
P. O. Schallert, of Winston-Salem, North CaroHna. 
The latter collection shows several fruits, all old; but one has a good peri- 
stome, which agrees well with :he one figured in Limpricht's Laubmoose, Vol. 1, 
p. 729. But here the similarity of this plant with Grimmia plagiopodia practic- 
ally ends. 
First, a hand-lens examination leads one to suspect that the small cushions 
have two species mixed: the sterile plants are dark green with all the leaves 
rounded at the apex, their costa ending well below it; scattered among these are 
groups of three or four leaves with long white hair-points as long as their lamina 
which turn out to be the perichaetial leaves of the fruiting plants or branches. 
Then, the seta, strongly crooked as in the other Gasterogrimmias is twice 
to thrice as long as the capsule, carrying the latter well to the top of the hair- 
points of the enveloping leaves. 
The spores which, according to Limpricht, I.e., measure 11 to 13 microns 
in Grimmia plagiopodia here measure 14 to 16 microns. 
Finally, the plant has leaf-margins rolled back and the lamina strongly keeled 
towards the apex and throughout unistratose, while Grimmia plagiopodia has the 
leaves described by Limpricht as flat (" flach-randig") agreeing with the sections 
in plate 236 in Bryologia Europea. 
Austin's species, like Grimmia plagiodia, is autoicous, the perigonial buds 
standing below the perichaetium. But the perigonial leaves are small, the inner 
ones reaching not over a third of the length of the stem leaves. They are closely 
rolled around the several antheridia and are with difficulty unrolled. These 
buds were too old to show whether paraphyses were present or not. The Man- 
ual says of the var. pilifera, p. 138; "perigonial leaves longer." Unless this is 
an error in observation, that variety may be a separate plant. 
Austin's plant is evidently a good species, distinct from Grimmia plagiopodia, 
distinguished by the entire absence of hair points on all stem-leaves, which are 
rounded at the apex and rolled hack at the margin, and by the long seta, and by 
the perceptibly larger spores. 
In closing, I wish to correct an error. In Minnesota Botanical Studies, 
in my report on the moss- flora of the Minnesota River, p. 115, I reported Grimmia 
Brandegei Aust. This is clearly not the same as the above described California 
plants, but is rather referable to Grimmia plagiopodia, simply with somewhat 
longer hair-points.
