but I found two fruiting plants, at the base of each of which arose a plant. The 

 leafy bud at its end had a few small club-shaped paraphyses, but no antheridia. 

 These may have disappeared, being very delicate; and the plants would thus 

 seem to be autoicous. Re-examination is necessary. 



The spores in the two plants differ considerably. Mr. Baker's plants are 

 younger, less mature. Mrs. Britton's description of size and markings applies 

 to the spores of the Nevada plant. In the Canadian plant the spores are of 

 the same shape, namely, kidney-shape; but they are larger, measuring 30X45 

 to 50^1. Their surface is distinctly and clearly spiny, there being now no "sinu- 

 ous lines of papillae," such as Mrs. Britton describes. I am persuaded that 

 this difference in size and surface marking in the spores of the two collections is 

 due to the difference in maturity, the Nevada plant being collected in June, 

 the one from Canada in July,

Note II — -Under date of March 18, 192 1, Dr. Holzinger writes as follows: 

 Since writing the remarks on Mrs. Britton's note on Physcomitrium pygma- 

 eum I have found, among material not yet distributed in my herbarium, a third 

 collection, made in Minnesota by the late Dr. J. H. Sandberg, which enables 

 the certain determination of this species as autoicous. From a common stem 

 arise two naked branches terminating in one leafy antheridial and one leafy 

 archegonial bud. Only in the antheridial buds could I find the strongly club- 

 shaped paraphyses similar to those figured in Engler & Prantl for Funaria hy- 

 grome/nca ( Die natiirlichen Pflanzenfamilian, 1 : 3 : 204, j^g, 1909). They 



appear to be entirely absent in the archegonial buds,

NOTES ON CURRENT LITERATURE OF MOSSES 



In a recently received article, M. Theriot^ clears up the confusion that has 

 existed regarding Syrrhopodon Taylori Schwaegr., S. Gardneri (Hook,) Schwaegr., 

 and Leucoloma Taylori (Schwaegr,) Mitt. From a study of the original speci- 

 mens in the Schwaegrichen herbarium, M. Theriot concludes that Syrrhapodon 

 Taylori Schwaegr. is really a Leucoloma, as Mitten concluded; that the plate 132 

 in the Supplement. II, i, correctly represents it, save the figures of the peristome 

 Nos. II and 12, which were by accident drawn from 6". Gardneri, as was all of 

 plate 131. The latter is a good species, founded on Calymperes Gardneri Hook. 

 M. Theriot also adds that according to specimens sent him by M. Cardot, C. 

 Mueller's Leucoloma sarcotrichum is wholly synonymous with L. Taylori. In 

 the same article M. Theriot states that Duby's Fabronia longidens is identical 

 with Dimerodontium pellucidum (Hook.) Mitt. 



M. Theriot has also favored us with copies of the list of mosses contributed
