[bnerthenema. 
0-75 mm, broad, Var, oblonga, sporangia 0-75 to 1 mm. long, 
0'3 to 0'5 mm. broad. 
Hah. Near Cracow. 
This description applies to a form of C. ohtusata with spores rather 
more distinctly warted than usual. 
Genus 17.— ENERTHENEMA Bowman, in Trans. Linn. Soc, 
xvi., p. 152 (1830). Sporangia stipitate ; columella reaching to 
the apex of the sporangium ; capillitium springing from beneath 
the superficially extended end of the columella. 
1. E. elegans Bowm., I.e., p. 152, tab. 16 (1830). Plasmodium 
watery- white. Total height 1 to 1-5 mm. Sporangia globose, 
stipitate, erect, gregarious, 0-5 to 0-75 mm. diam., dull black, 
crowned with the small iridescent salver-shaped apex of the 
columella; sporangium- wall evanescent. Stalk conical, black. 
Columella slender, cylindrical from a conical base, traversing the 
sporangium and expanding on the surface into a membranous 
umbilicate disc O'l to 0*2 mm. broad. Capillitium threads 
spreading from the expanded apex of the columella, long, slender, 
black, sparingly bi-anched, straight or flexuose. Spores greyish- 
brown, spinulose, 8 to 10 /x diam. — Mass., Mon., p. 105. Stemo-

Plate XLVII.jA. — a. sporangia, x 20 ; sporangia with spores dispersed, 
showing capillitium ai^ising from under the apical disc of the columella, x 
35 ; e. sporangia with capillitium arising from the whole length of the 
columella, and anastomosing to form more or less of a network ; found in 
company with sporangia with normal capillitium, x 35 ; d. spore, x 600 
(England). 
Occasionally the capillitium threads are much branched and spring 
from all parts of the columella, which may then terminate below the 
apex of the sporangium ; but all conditions between this and the normal 
form occur in the same group of sporangia. The account with the 
figure of Ancyrophorus crassipes Eaunkiaar, I.e., well describes this 
variety. In what remains of the type of E. Berheleijanum Eost., from 
S. Carolina (K. 1643), no spores of an Enerthenema can be detected ; 
the specimen is beset with clusters of brown spores or dividing cells of 
a parasitic fungus. Berkeley and Broome describe this specimen as 
having the " spores produced in little heads surrounded by a common 
vesicle at the free apices of the flocci," and of this being " almost the 
only case in which the spores of a Myxogaster have been observed in 
situ ■ Ptychogaster is the single exception." The sporangia are of the 
typical form of E. elegans, and it appears possible that the mould was 
mistaken by Berkeley "and Broome for the true spores.
