NOTES. 
No. 2515, Polyporus Telfairii , Klotzscb, appears to be an 
undescribed species. Tbe type specimens of P. Telfairii , from 
which Klotzsch drew up tbe diagnosis published in “ Linneea,” 
Yol. Yin., p. 484 (1833), are in the Kew herbarium, and in a very 
good state of preservation. The pileus is very thin, shrinking 
and becoming incurved when dry ; pores large, irregular, dis- 
sepiments very thin and becoming torn ; altogether closely 
resembling tbe pores in Polystictus abietinus. The words “ poris 
minutissimis ” can only be regarded as a slip of the pen, and such 
slips are very rare in Klotzsch’s work. 
Mr. C. Rea, who is desirous of making an exhaustive examina- 
tion of the Russulae, would be greatly obliged if British and 
Continental mycologists would kindly aid him in the study by 
forwarding fresh specimens to 34, Foregate Street, Worcester, 
during the present and succeeding seasons. 
MUSCINEiE. 
The British Moss-Flora , Part XV. By R. Braithwaite, M.D., 
F.L.S. 
The fifteenth part of this excellent work concludes the descrip- 
tions of the species of Bryum, and contains the whole of the 
Bartramiacese. The genus Bryum is divided into 38 species, as 
against 37 admitted in the last edition of Hobkirk’s synopsis. 
Of the reductions of species we note the following: — 
Bryum origanum , Bosw., becomes Bryum pallens , Swtz. 
Bryum Barnesi , Schpr., becomes Bryum ar gentium, L. 
Bryum obconicum. Hornsch., becomes Bryum capillare } var. 
obccnicum , Huebn. 
Bryum Schleicher i, var. latifolium , becomes Bryum turbinatum , 
var. latifolium. 
The synonomy (as in previous parts) has been worked out in 
detail, and has resulted in many changes of nomenclature. Of 
these s ome are due to the working of the law of priority, but it is 
doubtful what advantage can be derived from changing Bryum 
Donianum , Grev., into Bry. Donii , which, although “ Grev. ” is 
placed after it, should be “ Braithw.” Again, Bryum roseum , 
ISchreb. (1771), gives place to Bry. proliferum , published by 
Sibthorp twenty-three years later, the name having been used by 
Linnaeus in 1753 in a varietal sense only as Minum serpylli- 
folium , var. proliferum , L. Changes like these tend to confuse 
rather than elucidate. 
The Bartramiacese are divided into five genera, viz., Conostomum, 
Bartramia, Philonotis, Brentelia, and Catoscopium. Here it has 
not been found necegsary to introduce much change of nomen-
