60 CRYPTOGAMIA ANTARCTICA. [Auckland and 
5. SPHÆRIA (foliicole) depressa, Berk.; gregarea, minor, atra, peritheciis tectis subglobosis levibus 
callo destitutis siccitate depressis, sporidiis lanceolatis. (Tas. LX VIII. Fig. V.) 
Has. Campbell’s Island ; on the dead leaves of Luzula crinita. 
Gregaria, epidermide atro-punctato omnino tecta. Perithecia minora, subglobosa, callo destituta, siccitate depressa. 
Asci lineares, paraphysibus tenuioribus immixti. Sporidia biseriata, lanceolata, endochromio bipartito sed non septato. 
The only species with which the present can be compared are the S. duplex and $. saxifricola; from both these 
it will be found to differ by the external characters given above, and, from the latter in particular, by the simple 
pellucid and neither triseptate nor yellowish sporidia.

and paraphyses; 4, sporidia, shewing the endochrome collected at either extremity ; magnified. à 
6. DOTHIDEA*, Fries. 
1. Dornrpza hemispherica, Berk.; hypogena, solitaria, erumpens, macula subeffusa epiphylla nigra, stro- 
mate hemispherico carbonaceo, cellulis ellipticis obtusiusculis, ascis breviusculis, sporidiis uniseptatis oblongis.

Has. Lord Auckland's group; on the leaves of Veronica odora. 
* [ take the present opportunity of describing two new species of Dothidea, contained in the Herbarium of Sir 
W. J. Hooker. 
1. DOTHIDEA circumscripta, Berk.; innata, gregaria, maculis suborbicularibus irregularibus depressis nigris 
nitidis cireumscriptis, cellulis paucis magnis depresso-globosis, collo brevi, ostiolo papilleeformi, ascis clavatis, sporidiis 
oblongo-lanceolatis. (Tas. LXVIII. Fig. VI.) 
Has. Andes of Columbia (Jameson). Chacapoyas, Peru (Mathews) ; on various species of Vaccinium. 
Hypophylla, rarissime epiphylla, innata. Macule 3 lin. late, suborbiculares v. confluentes, irregulares, depresse, 
nigre, nitidee, quandoque leviter undulatze, minutissime granulate, ostiolis paucis papilleeformibus notate, linea nigra 
plus minusve evidenter cireumscriptee, demum omnino fatiscentes, et scutellam epidermide marginatam exhibentes. 
Cellule fructifere paucissimee, magne, globose, depressse, collo brevi, ostiolo papilleeformi. .4sci clavati. Sporidia 
octona, oblonga, hinc acuminata. : 
A very pretty species, remarkable for the small number of fructifying cells and the dark line enclosing the stroma, 
which is especially evident when the latter is abortive; beyond this line there is sometimes a coloured ring. The 
sporidia are almost of the same shape with those figured by Corda, in Rhytisma Bugeniacearum ; when young they 
are filled with distinct granules which become less evident as they are more developed. In age the stroma com- 
pletely decays and falls out, leaving a scutellum surrounded by the cuticle. "This follows from the dark line indi- 
cating a harder substance than that of the stroma, which is not always externally visible, but will be found on making 
a vertical section. 
PrATE LXVIII. Fig. VI.—1, a branch of Vaccinium and fungus of the natural size; 2, a section, slightly mag- 
nified ; 3, asci, slightly magnified; 4, sporidia, highly magnified. 
2. DOTHIDEA bullata, Berk.; epiphylla, bullata, suborbicularis, nigra, superficialis, crassiuscula, rugosa, granu- 
lata, intus nigra, cellulis ellipticis, ostiolo papilleeformi, ascis oblongis, sporidiis oblongis uniseptatis.
