tions lead him to aes that the epiphyllous cryptogam in question 
supports the view that a en is a compound organism composed 
stellate patches, greyish green blotches, clear grey spots, and white 
shining circles,—but these pass imperceptibly into one another, and 
vary in size from a speck to a quarter eg an inch in diameter. 
The reddish sept of the earlier Seon an Alga, # which ane

hyphe, which produce black dots, viz., the fruit-bodies. The author 
describes in detail the peculiarities of growth and reproduction of 
the Alga and fungus, and formation of the Lichen. He alludes to 
and criticises Dr. Cunningham’s account of Mycoidea parasitica, 
which latter is evidently closely related to that described by himself. 
Assuming that Mycoidea and Ward’s Alga are se Re, 
same, either Cunningham discovered a female organ of jay nie star te 
which becomes fertilized and produces zoospores, or he confounded 
this with fertile hair-organs. As regards the systematic fact of 
the Alge, a eg aR with Colecheta suggests that there is very 
little in common, be mode growth, of the disk-like thallus 
and the produstion of eens s from certain cells. The genus 
h agree in several 
important oints, viz., orange-r red oily cell-contents, habitat, 
ar of zoospores in ovoid cells developed terminally and 
latera The structure of the thallus and relative positions of the 
ei oe of fungal and algal portions agree with what occurs in 
heteromerous crustaceous Lichens, as Graphidea; but the peri- 
thecia indicate an angiocarpous alliance, bringing this form nearer 
such families as Pertusaria and Verrucaria, to the latter of which 
it may ultimately be referred. i :
