Cladonia cariosa corticata Wainio, Mon. Clad. Univ. 2 : 53. 1894. The 
cortex subcontinuous or partly areolate with the areoles contiguous. 
Examined from Indiana (L. M. Underwood) and from Tacoma Park, D. 
C. (T. A. Williams). Also a peculiar form from Maine (G. K. Merrill) doubt- 
less belongs here, though squamules are present at the tops of the podetia. 
The specimens seen are less branched than the usual forms of the species. 
Miss Clara E. Cummings also lists this variety from Alaska, and Dr. Wainio 
thinks that most of the forms given by Tuckerman under C. symphycarpa 
probably belongs here. Known also in Europe. 
Cladonia cariosa squamulosa (Mull.) Wainio Mon. Clad. Univ. 2 : 57. 
1894. Squamules of the primary thallus somewhat elongated, and squam- 
ules present on the podetia. Cortex of podetia sometimes subcontinuous. 
Podetia sometimes simple. 
A specimen sent by Prof. John Macoun, collected on the lower St. Law- 
rence, in Ontario, is this at least in part, squamules being quite numerous on 
some of the podetia, even to the top. Collected on humus over rocks. 
Known elsewhere only in Europe. Grinnell, Iowa. 
MUSCI ACROCARPI BORE ALI= AMERICAN A. 
(Prepared and Distributed by Prof. J. M. Holzinger.) 
Prof. Holzinger has just issued the last fascicle of Century n, of this 
interesting and valuable series. In the last two fascicles we note the 
following interesting species: Oligotrichum parallelum (Mitt.) Kindb. 
Pogonatum erythrodontium Kindb., Fissidens Ravenelli Sulliv., Blindia 
acuta fiexipes R. & C., Distichum inclinatum (Ehrh.) Bry. Eur., Grimmia 
glauca Card., G. Muhlenbeckii Sch., Rhacomitriwn patens (Dicks.) Hueb., 
Scouleria marginata E. G. B., Barbula amplexa Lesq., B. Bakeri Card. 
& Ther., Pottia Nevadensis Card. & Ther., Aphanorkegma serratum 
(Hook. & Wils.) Sulliv., Orthotrichuin papillosum Hpe., Schlotheimia Sul- 
livantii C. M., Ulota phyllantha Brid., Timmiella anomala (Bry. Eur.) 
Limpr., Splachnum sphaericum L., Tayloria serrata B. & S., Pyramidula 
tetragona Brid., Bartramia glauco-viridis C. M. & K. , Bryum Bailey i 
Holz., B. polycladum Card. & Ther., Rhizogonium spiniforme Bruch. 
Dr. J. W.hBailey and Mr. A. S. Foster in the Northwest, and Mr. Severin 
Rapp in Florida, 'are doing remarkably good work as collectors, and are adding 
extensively to our knowledge of the moss flora of their respective regions. 
Several other members of the Sullivant Moss Chapter have contributed 
to Century 11, and it is safe to say that Prof. Holzinger’s Exsiccati, as well 
as my own, have been very greatly indebted to the work of the Chapter. 
Mr. Rapp, living in one of the most interesting regions bryologically of all 
North America, is doing specially fine work. 
To my own Exsiccati he has contributed such things as Hookeria var- 
ians , Leptodon trichomitrion immersum , Pilotrichella cymbifolia, Papil- 
laria nigrescens, Clasmatodon parvulus , Entodon Drummondia , and others 
of equal interest. A. J. Grout.
