the sporangium, subclavate, filled with cells like the stem ; 
capillitium dense, almost colourless in every part, originating 
from the apex of the columella and at once forming an irregular 
network, without the usual primary undivided branches ; threads 
irregular in thickness, arcuate, often flattened, and triangular at the 
nodes, spores globose, dingy purple, coarsely ecbinulate, 18-22 
/a diam.

2040. Lamproderma Listeri. Massee Mon. p. 97. 
Sporangia stipitate, globose, blackish-purple, iridescent, lower 
portion often persistent as a ragged frill round the stem ; stem 
elongated, straight, or subflexuous, conical, smooth, blackish-brown, 
filled with amorphous lumps of organic matter, expanding at the 
base into a hypothallus ; columella slender, about one-third the 
height of the sporangium, slightly incrassated or expanded in a 
discoid manner at the apex; capillitium rather dense, the main 
branches springing from the apex of the columella 3-4 p thick, 
simple for half their length, then 2-3 times dichotomously branched ; 
branches becoming thinner towards the tips, straight, sometimes 
anastomosing laterally, free tips colourless, other parts dark ; 
spores globose, dingy purple, coarsely spinulose, 15-17 p diam.

Section 3. Calotricheas. 
Wall of sporangium without an external deposit of lime, 
capillitium present, not springing from a columella. 
Sub-Section ). Arcyrise. 
Threads of capillitium either attached by one end, with the free 
tips more or less branched, or combined to form an irregular net- 
work. 
Genus 6. FEHICHJENA. Fries. 
Sporangia sessile, gregarious, dehiscing irregularly or in a cir- 
cumscissile manner; wall usually double, the outer often containing 
granules of lime, or a layer of granules of organic matter ; 
capillitium variously developed, in some species forming an 
irregular network, in others almost obsolete ; threads of capillitium 
without definite markings ; spores globose.

Sporangia spherico-depressed, crowded, dehiscing in a circum- 
scissile manner ; lid convex, brown, bluish-purple, sometimes 
whitish, smooth ; mass of capillitium and spores pale yellow ; 
capillitium scanty, sometimes almost obsolete ; threads thin, 
smooth, or here and there notched ; spores globose, warted, warts 
variable in size, sometimes very indistinct, at others well developed, 
never smooth, 9-12 p diam.
