Differs from the typical form in the smaller size of the
sporangium and longer stem.
United States.
lachnobolus Rostafinskii, Racib.
Sporangia stipitate, ovate-conoid, apex rounded, yellmuish-
grey, lower portion o f spcrrangmm with a distinct membrane,
hemispherico-patelliform, the upper portion destitute o f a membrane,
capillitium well-developed, forming a net adnate to
the peridium by numerous branches, the upper portion with
numerous free h'anches; threads with thin, plate-like processes
forming a reticulation, varying from 4'2—8'2 g diameter; spores
yellow, membrane firm, smooth, 7'5—8'3 g diameter.

Very closely allied to Lachnobolus globosus.
Poland.
Lachnobolus arcyrella, Rost.
Sporangia pirifm-m, fulvous or almost straw-coloured, stem as
long as sporangium, or slightly shorter, sub-gilvous; capillitium
not elastically extruded, forming a lax irregular network, threads
2'5—8'3 g diameter, attached at many points to the sporangial
wall, sometimes descending into the hollow of the stem, ornamented
with numerous obtuse, small ivarts; spores smooth, 7 — 8 g
diameter.

Lachnobolus inoarnatus, Schroet.
Sporangia when free globose or elongated, sessile, usually
clustered and forming a plasmodiocarp, wall thin, brittle, pinkish,
becoming broion, smooth, shining, dehiscing irregularly; mass of
spores fiesh-colour; threads of capillitium combined to form a
dense n e t; 4— 3 g thick, orna/mentcd with warts and' short,
irregular lands, incrassated at the nodes ; spores globose, smooth,
6—8 g diameter.

H eteeotkichia, Mass. (Nov. Gen.).
Sporangia densely crowded or scattered, stipitate ; wall single
thin, upper portion disappearing at maturity, leaving « ’e basal
portion as a calyculus; stem filled with large, thiok-walled cells
that are sub-angular from mutual pressure; these become smaller
upwards, and pass gradually into normal spores ; capillitium
free from wall of sporangium, its lower branches passing between
the cells filling the stem, central portion composed of very thm
tubes anastomosing to form a loose, irregular network; towards
