348 CACOMA PINIQUATORUM. 
of Meggy's Burn, near Blyth. Mr. T. J. Foggitt has just shown it to 
me, also from the Durham coast, near Seaton Carew. It is new to the 
Tyne province, and Mr. Watson (' Cybele,’ iii. p. 338) considers that 
its occurrence at all on the east side of Britain requires confirmation. 
Good specimens of P. microspermum, Jord., were obtained near the 
- same place in Northumberland, yy Aras 
Juncus diffusus, Hoppe. Banks of the little stream not far from 
Bardon Mills Station, where the Hieracium, formerly called by Babing- 
ton rigidum, variety pictum, grows. í 
Triticum acutum, De Cand. Plentiful at St. Mary’s Island, and 
growing also upon Hartley Links. Leaves with closely-placed, rough, 
hairy ribs, hardly at all enrolled, except quite at the apex, and the 
point not sharp, axis of the spikelets smooth. : $

ON THE NATURAL ORDER CHARACEÆ. 
Professor A. Braun, in his monograph of this Natural Order, stated 
at the above-mentioned meetings, that according to the latitude al- 
lowed by different authors to species, the genus Nitella comprised 
from 50-76 species (13-16 European), To/ypella from 6-1. (4 Euro- 
pean), Lychnothamnus from 3-5 (2-4 European), and Chara from 
56-80 (22-28 European). Some of them enjoyed a most extensive, 
others a very limited geographical distribution. . He exhibited a Chara 
from Lake Titicaca, Bolivia, which could not be distinguished from 
Chara Baltica; and as the most recent European discovery, Nitella 
ornithopoda, found by M. de Rochebrune about Angouléme. 3b 
; CACOMA PINIQUATORUM, De. Bory. | 
This Fungus, which has hitherto been found only about Hanover, has 
recently been discovered by Professor Ratzeburg near Neustadt-Bbers- 
walde, and is curious because it disfigures the Pine-trees by producing 
most singular contortions of their branches. It may possibly turn vp 
in other parts of Europe also. a
