OF FILAMENTOUS, FRUTICULOSE, AND FOLIACEOUS LICHENS. 203 
Specimen 1.—On old trees, Inverary ; in Herb. Botanical Society, Edinburgh ; 
coll. by MauecuHan; apothecia abundant. The spermogones are plentiful, scattered 
about the periphery of the thallus as regularly formed, very prominent cones or 
papillee, readily visible to the naked eye. The ostiole is brown, circular, apical, 
distinct. The sterigmata are ramose, thick, irregular in outline, formed of short, 
cubical, or irregularly shaped articulations or cellules, which have very thick walls. 
With age, they acquire a greenish tint. From among these project a number of 
long, sterile, ramose, articulated filaments, of the character of those of Ramalina ; 
but neither so delicate nor soramose. The spermatia are longer than is usual 
in Sticta, being about sth to snth long; they are found in abundance only in the 
youngest spermogones. 
Specimen 2.—On young oak, Cawdor Wood, Nairn; coll. A.CroaLu; in Herb. 
Hooker, Kew. Spermogones are plentiful, but there are no apothecia. Appin ; 
coll. CARMICHAEL; in very large patches, with both apothecia and spermogones ; 
also in Herb. Hooker. 
Specimen 3.—Kerry, Ireland; in woods; TayLor in Herb. Mackay, Dublin. The 
spermogones are abundant; the older ones become flattened, and have a stellate- 
fissured, large, brown ostiole. The spermatia are apth to anth long, and smth 
broad ; the sterigmata are about anth broad. 
Specimen 4.—Killarney ; in Herb. Royal Botanical Garden, Edinburgh ; with 
apothecia. Spermogones large and abundant. 
Specimen 5.—Lachen, Sikkim, Himalaya, alpine region, at 11,000 feet, Dr 
Hooker ; in Herb. Hooker, Kew; withapothecia. Some of the spermogones are 
seated directly on the margin of the thallus, forming a kind of teeth, as in the 
denticulate form of Parmelia perforata. Their form is more that of a barrel than 
of a cone. 
Specimen 6.—South Africa, DrecE (sub nom.' Sticta quercizans, Ach.); Dax, 
Pyrenees, Spruce’s ‘“‘ Lich. Pyrenzi;” in Herb. Hooker, Kew. In both the sper- 
mogones are plentiful. 
Specimen 7.—LEIGHT. exs. 75 (sub Sticta, Delise, “‘ Eng. Bot.” 294); Ayrshire. 
The spermogones are subperipheral, large, and frequently confluent. 
Specimen 8.—ScH&RER exs. 560 (sub Parmelia letevirens a. simplex). On 
trunks of trees about Vire, PELVEr. Spermogones are plentiful. The spermatia 
are about sth long; the sterigmata th to mth long, 
Specizs 2. R. glomulifera, DN., 
Which occurs in Europe, America, and Asia. 
(Syn. Sticta amplissima, Kors, 68 ; Parmelia, Ach.) The spermogones are 
exactly those of the preceding species, but they are scarcely so prominent.
