CHLOROGLOEA 13 
indefinite extent, the patches being sometimes 15 mm. or more in 
diameter; the cells are mostly 1-2.5 шіп the longer diameter, are 
subglobose or oblong, 1-2 times as long as broad, in obvious 
vertical rows and compactly imbedded in a rather inconspicuous 
jelly; the color of the colonies as they come to us preserved in 
fluid is a dilute yellowish green, though individual cells show a 
bluish tinge under the higher powers of the microscope; the struc- 
ture of the protoplast is clearly of a Cyanophyceous character. 
In the thickness of the stratum and in the number of cells in the 
rows, Dr. Coker’s plants apparently resemble the original figures 
by Hangsirg more than the later figures by Wille. It may, how- 
ever, be remarked that we have been unable to see sheaths for 
individual cell rows so distinctly as figured by these authors. 
Chlorogloea endophytica sp. nov. 
Forming endophytic yellowish-green corticicolous colonies, 
these mostly 20-1104 broad and suborbicular or irregularly 
stellate or radiate in surface view, penetrating thallus of host about 
30-170 и and often a little protuberant; cells somewhat angular, 
ellipsoidal or subspheric, 0.7-2.5 и (mostly 1-1.5 и) in diameter,
