brown, 3'5-5 /x thick, branches opposite or alternate, anastomosing ; hypho- 
podia alternate or unilateral, 2-celled, occasionally sessile, 1 -celled, 10-15 x 
8-12 fJL, most frequently palmately 3-4-lobed and obliquely septate between the 
first and second lobes ; thus the stipe cell is gibbous and the terminal cell 
has 2-3 blunt lobes. Thyriotliecia 100-160 /x diam., hemispherical, dehiscing 
by an irregular central fissure, which later becomes stellate ; composed of 
radiating cells, 3-3*5 /jl diam., margin fimbriate. Asci aparaphysate, spherical 
to obovate, 30-50 x 25-30 fx, 8-spored. Spores conglobate, brown, oblong, 
18-22 X 7-10 /X, upper loculus sub-globose, lower loculus narrower. Pycnidia 
similar to the thyriothecia but smaller, about 70 /x diam. ; conidia continuous, 
brown without a hyaline band, ovate to pyriform, 17-20 x 6-10 /x.

Theissen (Die Gattung Asterina) makes this a variety of A. pseudo- 
felliculosa, from which it differs in the 2-celled liyphopodia, on the grounds 
that in the Brazilian specimens of A. i)eraffinis 1-celled liyphopodia are also 
found. In my specimens 1-celled hyphopodia are rare or absent, and it 
appears to me that the fact that the majority of the hyphopodia are 2-celled 
is sufficient to separate this species from A. pseudo'pelliculosa, where they 
are constantly 1-celled. Theissen also mentions f . africa^ia = Asterina 
Stroijhanthi P. Henn., Engl. Bot. Jalirb. 38, p. 125, on Strojohanthu^ 
hispidus, Togo, Africa, Eelim. Ascom. 1624, Herb. Berlin. This form, 
which is not represented in the National Herbarium, has some 1-celled and 
some 2-celled hyphopodia, and is an intermediate form between A. peraffinis 
and A. pseudopellictdosa.

Mostly epiphyllous ; hyphae brown, undulate, 3*5-5 /x thick, with cells 
20-24 ju, long ; branching irregularly to form a network of anastomosing 
hyphae ; hyphopodia alternate, stipitate, straight or curved, the terminal 
cell lobed, 9-13 /i high and 6-10 (a, broad. Thyriothecia 85-100 /u diam., 
hemispherical, dehiscence stellate, margin fimbriate ; composed of radiating 
hyphae 3-3-5 yu thick, cells 4-5 /x long. Asci ovate to globose, 23-30 x 
26-33 fi, aparaphysate, 8-spored, thickened round apex, not stained blue by 
iodine. Spores dark brown, epispore strongly echinulate, rounded at both 
ends, 2-celled, constricted, 16-18 x 8-9 /x, rarely 20 /x long, upper loculus
