PITHOPHORA. 131 



Syn. Cladopliora Vauclierioides, Wolle, 1878. 



Plate CXIII, figs. 1, 2, 3, parts of three fertile stems with 

 inclosed and terminal spores ; figs. 4, 5, sporal branches ; 

 figs. 6, 7, two parts of filaments as first found, in an im- 

 mature condition. 



PITHOPHORA .EQUALIS, Wittr. 

 Yar. FLORIDENSE, Wolle. 



Principal filament of the cauloid part of the thallus in 

 fertile specimens on an average 175 /* thick (Wittr. 102), 

 more or less swollen, either with branches of two degrees, 

 (those of the first, few and long, those of the second, short) 

 or with branches of only one degree, numerous and short ; 

 spores single or more rarely double, inclosed in the prin- 

 cipal filaments or in the branches of the first degree ; more 

 seldom terminal ; the inclosed spores cask-shaped with 

 somewhat rounded ends, on an average 120 /* (Wittr. Ill) 

 thick and 215 ^ (Wittr. 250) long ; the terminal spores cask- 

 shaped, with upper end conical and the apex somewhat 

 rounded ; on an average 90 ^ thick, and 270 /* long. 

 Collected by J. D. Smith, Florida, 1878. 



A character peculiar to this variety is noticed in the swol- 

 len cells and in their larger diameter. 



Plate CXIY, figs. 1, 2, two fragments of fertile filaments ; 

 figs. 3, 4, 5, three spores, simple and branched. 



PITHOPHORA KEWENSIS, Wittr. 



Principal filament of the cauloid part of the thallus in 

 fertile specimens on an average 59 /^ thick, with solitary 

 branches of only one degree, or rarely of two degrees ; 

 spores single, partly inclosed, partly terminal ; the inclosed 

 spores cask-shaped, but more elongated ; on an average 81 ^ 

 thick and 205 // long ; the terminal spores cask-shaped, with 

 upper end conical ; apex somewhat rounded, on an average 

 88 // thick and 219 ^ long ; the rhizoid part of the thallus 

 as a rule unicellular. 



Found in Florida (March '85) on the planked sides of the 

 outlet of the large sulphur springs at Green Cove Spring, 

 growing just above the water line, a plant, in caespitose 

 clusters one-half to one inch long; it has the size and the 

 features of this Pithophora, but being sterile at the time of 

 collection could not be identified with certainty. The diag- 

 nosis above is from Wittrock's Monograph.
