pears to be a good species though all the specimens I have 
seen have immature spores. 
12. Asterella Pringlei, n. sp. 
Gametophyte 1-1.5™ long, 2-4™" wide, bright green, 
fleshy, thalloid, closely adherent to the soil, depressed along 
the center, the margins thin, areolate-veiny, irregularly 
crenate-undulate, greenish below with a few slender whitish 
lanceolate scales, and numerous root hairs along the midrib; 
@ branch slender, 1-1.5™ high, brownish, lighter above, 
naked throughout; receptacle subglobose, much wrinkled when 
dry, with one or two somewhat divergent involucres; inner 
involucre white, about 12-cleft, the divisions cohering at 
their apices. Sporophyte sessile, with large brown or almost 
black spores that are tetrahedral, 118-135 in diameter, narf- 
rowly winged and covered with narrow reticulations; elaters 
about two and a half times as long as the diameter of the 
spores, with 2-3 spiral fibers. 
Wet cliffs near Gaudalajara, Mexico, Pringle (Sept. 1! 
1890). 
13. Asterella Austini, n. sp. : 
Gametophyte 1-2™ long, 2-3 wide, thalloid, plane, thin, 
green above and beneath with here and there occasional 
spots of purple, with narrow brownish scales and more or less 
copious root-hairs near the midrib beneath; @ branch I” 
or more high, brownish, sparingly pilose but the hairs becom 
ing more abundant at the apex; receptacle somewhat tuber- 
culate above with 1-3 more or less divergent involucres; inner 
involucre brownish or dirty white, about 8-cleft, the divisions 
coherent at their apices. Sporophyte a sessile yellowish cap- 
sule; spores yellow, 110-118#in diameter, broadly winged and 
distinctly reticulated; elaters about twice as long as the di- 
ameter of the spores with two irregularly coiled spirals. 
Cuba, C. Wright. Distributed by Austin as Fimbriarta 
elegans (Hep. Bor.-Am. 136 c) which (as represented in my 
herbarium) forms the type of this species. The specimen of 
this number in the Gray Herbarium agrees with mine except 
that it lacks mature spores. The set in the Herbarium of 
Columbia College lacks this number. I should be pleased to 
have others who possess sets of Austin’s exsiccate compare 
their specimens with the above statements. 
14. Asterella Wrightii, n. sp. 
Gametophyte 1-2™ long, 2-3™ wide, thalloid, deeply
