8. H, chrysospora Lister. Plasmodium? Sporangia sub- 
globose, sessile, crowded or scattered, 0-5 to 1 mm. diam., glossy, 
bright yellow ; sporangium-wall membranous, with minute 
thickenings in the form of a broken irregular reticulation. 
Capillitium a network of branching, yellow threads, 5 /a diam., 
with four to five narrow bands arranged in a close, regular spiral, 
and connected by longitudinal strise ; the threads provided with 
many shortly pointed free ends, and attached to various parts of 
the sporangium-wall. Spores yellow, reticulated with narrow, 
sharply defined bands, forming a regular net with six to nine 
meshes to the hemisphere, 16 to 18 [x diam. ; border 1-5 to 2 fj. 
broad. — Hemiarcyria chrysospora Lister, in Grev., xv., p. 126

This species was first found on fallen twigs and moss in a larch 
plantation near Lyme Eegis, November 1886. A small gathering was 
obtained in another larch plantation near the same place in November 
1890, agreeing in all respects with the above, except tbat the capilUtium 
consisted of long free elaters.

9. H. calyculata Speg., in Annal. Soc. Cient. Argent., x., 
p. 152 (loSO). Sporangia simple, gregarious, stipitate, globose 
or ellipsoid, 1 to 2 mm. diam,, dull fulvous-brown. Stalk 2 to 5 
mm. long, 0'2 to 0"25 mm. thick, terete, glabrous, firm, expanded 
above into a cup which is half the height of the sporangium, 
the base expanded, fibrillose, concolorous. Capillitium and spores 
dull yellow ; elaters 7 to 8 /a thick, branches few, with pointed 
free ends, cylindrical ; spiral bands three to five, even, somewhat 
inconspicuous, with interspaces of equal width, spiuulose. Spores 
discoid-lenticular, margin muricate, 10 x 3 /a.

This description suggests a form of Hemitrichia elavata. 
10. H. melanopeziza Speg., I.e., xii., p. 257 (1881). Sporangia
