All the white-spored branched species given in the preceding 
table are terrestrial. C. trichopus I have found only among 
sphagnum. C. cristata rarely occurs with branches obtuse, and 
not crested. C. spenulosa rarely may be found without white tips 
to the branches, but in every instance of such exceptional forms 
coming under my observation, they have been associated with a 
great abundance of the normal form. C. inequalis grows especi- 
ally in swamps and sometimes singly. It is quite fragile. C. 
mucida is remarkable for the green confervoid stratum that covers 
the moist rotten wood on which it grows. 
Genus—ACIDIUM Pers. * 
Peridia tubular or cup-shaped, at length open at the top with the 
margin lobed or lacerated ; spores subglobose, colored. 
The peridia normally occupy the lower surface of the leaves of 
plants, sometimes scattered over the whole of that surface, but 
more often collected in little orbicular clusters. They open at the 
top, revealing the globose or ovate, yellow or orange-colored spores 
within, and are not inaptly termed ‘* Cluster cups.’ The margin 
of the cup or peridium is generally fringed or scalloped with little 
rounded, reflexed lobes. The subiculum or spot on which the 
cups are seated is usually more or less discolored, yellow and red 
being the prevailing hues. The spermogonia, minute pustules 
which occur with the'cups and are thought to be the male plant, 
are not always readily detected. They usually occupy the center* 
of the spot on one or both sides of the leaf. More than thirty 
species of A‘cidium have been found in the State, of which the 
following is a synopsis. 
a. Peridia scattered over the whole under- « 
surface of the leaf, or over indefinite portions 
of it.
