THAXTER. — MONOGRAPH OF THE LABOULHENIA* EA . * 3' 3 
Laboulbenia minima Thaxter. 
The figures drawn from the material available at the time my Monograph was published, giw hut an 
inadequate idea of the appearance of full grown sp< im ens of this well marked and rather variable specie^

Agra sp., South America: Paris Collection; No. G8-0!) on Callida spp., VenesoeU. All these forms, 
though undoubtedly referable to this species, show a certain amount of variation, in coloration, in the 
degree and conspicuousness of the punctation, which is sometimes very marked even on the perithectum 
in the conformation of the tip of the peritheeium, which is sometimes flat topped and peculiarly modified, 
and in the development of the appendages. The latter arise in crot-like serii from the basal evils: on- 
such series from the outer, which may consist of seven or eight members which arise by successive prolifer- 
ation from the inner angle of the basal cell and are variably branched and suffused; the inner basal cells 
producing a somewhat similar series on either side. The general tv]>e is similar to that seen in L. hmgi- 
coll is which, although so very different in general appearance must be considered as not remotely related 
to it. On species of Agra in the Hope Collection, and in the British Museum, specimens occur in which 
the differences are so considerable that I think these forms may perhaps be specifically separated; but 
I have preferred to defer any further account of them until I have an opportunity properly to illustrate 
the present species, figures of which could not conveniently be included in the accompanying plates. 
Laboulbenia Brachini Thaxter. 
This species replaces L. Rougetii on American Brachini, but although very similar in form and color, 
cen 
<• 
peel- 
septa of their branches, and in the grouping of the antheridia. Simple forms of tins 
there is no proliferation of the basal cells, are hardly distinguishable from some South African specimen 
of L. Rougetii, and in one instance typical L. Brachini was obtained on a specimen in the British Museum 
labeled "B. oblongus Dej. Tangier, Africa." That there is some error, either in my own, or m the Museum 
label, I feel quite sure; since this is the only instance among the very large number of ha.stern-1 hm..- 
phere Brachini which I have examined, in which a form like L. Brachini has been observed. L Roup** 
var. Japanensis, with its dense stout appendages bears a superficial resemblance to tins species, but then- 
is no doubt in my own mind as to the distinctness of the two.
