CURRENT LITERATURE 
In the December issue of Rhodora , Dr. Evans 1 continues his series of notes 
upon hepatics, bringing up to date the local flora records for the New England 
States, and giving more detailed accounts of certain species. There is a note 
upon the probable identity of Sphenolobus ascendens Warnst. with Lophozia 
porphyroleuca, and a discussion of the distinctive features, ranges, synonomy 
and general history of Riccia Frostn, Aust., Scalia Hookeri (Lyell) Gray, Har- 
panthus Flotowianus Nees, and Calypogeia fissa (L.) Raddi. All these species 
have recently been found within the limits of New England. 
In the same journal Dr. Howe 2 has published a list of seven species of lichens 
that are additions to the two lists of Nantucket lichens previously published 
by him in Rhodora. 
In the December issue of Broteria there is a continuation of Senhor Sam- 
paio’s 3 lists of Portuguese lichens. There is an annotated list of fifty species 
or varieties, and a list of new localities for species mentioned in previous lists. 
One new variety is published in Alectoria, and the descriptions of six new species, 
recently published in "Annaes scientificos da Academia polytechnica do Porto, 
Vol. XII,” are given in full. In the last case, however, there are apparently 
some changes of name, so that there are three new combinations in the present 
article. 
"Because there was an older Thamnium Klotsch, the moss of that name 
must receive another. Thamnobryum may be suggested.” 
With this introduction, Dr. Nieuwland 4 makes new combinations for eight 
species of the genus Thamnium. Of these species five are American, one is 
British and local, and two are Sumatran (according to Brotherus).

Sullivant Moss Society Note 
When it was announced that the 1918 meeting of the American Association 
for the Advancement of Science would be held in Boston, plans were made 
immediately for holding a meeting of the Sullivant Moss Society at the same 
time and place. Recently, however, word has come from the Secretary of the 
Association that the Committee on Policy has changed the place of the meeting 
from Boston to Baltimore, and that it is planned to make the meeting a limited 
one, in the sense that the programme will be largely confined to definite working 
problems relating to the war. In view of this decision of the main association,
