Before bringing this paper to a close, a few words must be said on Stahl’s 
discovery of the sexuality of Lichens. See his Beitrage zur Entwickelungsge- 
schichte der Flechten, 1877. The spermagones had been discovered for quite 
a while, and several investigators had already made extensive studies regarding 
them and their enclosed spermatia. Tulasne, 1852, for example, had studied 
them and believed that they were peculiar reproductive organs closely related 
to the apothecia. Lindsay also studied them, and was inclined to believe them 
male reproductive organs. Stahl now concludes that in Collema, one of the ge- 
latinous Lichens, the spermatia are the male reproductive organs. The female 
reproductive organ he calls a carpogone. It consists of a spirally rolled portion, 
the ascogone, and a slender hyphal portion the trichogyne; the ascogone is in- 
side the thallus some distance below its surface; the tip of the trichogyne pene- 
trates the surface. Fertilization takes place by the spermatia coming in con- 
tact with the tip of the trichogyne, later resulting in the formation of an apothe- 
cium with asci and spores. Stahl’s results have been verified and similar repro- 
ductive organs have been found in other species of Lichens. However, not all 
Lichens behave in this way, as many of them form their fruits apogamously; in 
fact, there are a number of different ways, many of the supposed apogamous 
Lichens, for example, are now believed to have internal trichogynes and internal 
spermatia. Then again some investigators have demonstrated that the sper- 
matia will develop a hyphal net-work, even developing new spermagonia, which 
would seem to show that the spermatia, in some cases, are true spores instead of 
sexual organs. As a matter of fact, our knowledge regarding the formation of 
reproductive organs, apothecia, and other structures is very meager, and many 
more investigations must be made before we can feel sure of the results.

MOSSES OF THE CASCADE MOUNTAINS, WASHINGTON 
COLLECTED BY J. A. ALLEN 1 
M. E. Seymour 
The mosses collected in the vicinity of Mt. Rainier by J. A. Allen and his 
father were distributed in sets, several years ago. As there are still a number 
of these sets which have not been disposed of it may be well to put on record the 
names of the mosses as they are a very fine set of specimens, in good fruiting 
condition, and include some rare or unusual species. 
Alsia abielina, Amphidium lapponicum, Anhtrichia californica, A. curli- 
pendula, var. gigantea. 
!The names used in this article are those under which the mosses were distributed, thus differ- 
ing in some instances from present usage.
