On rotten pine wood. Scotland ; Sweden ; Germany.
Gregarious, several often springing from a common hypothallus;
2 3 mm. high, resembling superficially some forms
of C. macrocarpa, but at once distinguished by the large,
iiiegularly stellate, distinct nodes of the network, connected by
slender strands.
Cribrarla maorocarpa. Schrad. (f. 110).
Sporangia broadly obovate, stipitate, erect, upper portion
yellmoish-h'omi, calyculus h'oionisli-purph, funnd-slmped, occupying
one-third or more of the sporangium; sometimes perforated
towards the very irregular margin, the projections of
which are prolonged as flattened, granulose, coloured, irregularly
curved bands of varying width, and anastomosing a t various
points, with numerous lateral projections which are continuous
with the projections of adjoining ribs as thin strands bridging
the irregular meshes formed by the larger ribs; stem stouL
erect, simple, or 2—3 more or less grown together, purple-
broivn, rugulose, expanded at the base into a spreading hypothallus;
spores pale yellow, globose, smooth, 7—10 g diameter.

On decayed wood. Britain (Glamis, N. B.) ; France ; Switzerland
; Germany ; Sweden.
Crowded or scattered, sometimes 2—3 more or less combined
to foim an aethalium. The obovate sporangia and peculiar
structure of reticulation characterize the present species, the
broad, flattened, primary ribs by irregular bifurcation, combine
to form a network of irregularly elongated meshes, which are
bridged over by lateral thin strands from the sides of the
larger ribs. Well-defined distinct nodes connected by thin
strands are absent.

(1797). '
Trichia mcwrocarpa, Poir., Ency., 1. c. viii., no. 30 (1808).
Gribraria purpurea, Schrad, (f. 109).
Sporangia globose, stipitate, dark purple, calyculus well-
developed, with thickened ribs, sometimes irregularly perforated
near the dentate margin; nodes of network containing purple
granules, small, usually elongated, hut very irregular in form,
with numerous processes, connecting threads thin, some o f the
processes arc prolonged into simple or branched irregularly bent
threads that remain free at the tips, and not connected with
other nodes or threads; stem elongated, flexuous, purple; spore-
mass dark purple, spores almost colourless, or with faint tinge
of rose, globose, smooth, 5—7 g diameter.

On decayed pine trunks. Germany; Britain (specimen in
Herb. Kew marked, “ Herb. Dawson Turner, British ”); Sweden
(specimen collected by Lindblad, and communicated to Berkeley
by Fries).
Gregarious or scattered, about 1’5 mm. high, stem 3—4
times as long as sporangium, usually more or less flexuous.
Agrees in colour with G. elegans, but readily distinguished by
the smooth spores and numerous free ends in the permanent
network of the sporangium. Distinct from C. macrocarpa in
the globose sporangium and long, slender, flexuous stem.
Gribraria aurantiaea, Schrad. (f. 104).
Sporangia globose, usually more or less cernuous, orange
brown, calyculus occupying one-third or more of the sporangial
wall, furnished with ribs which pass upwards to form the network,
nodes coloured, containing granules, large, irregular, united
by thin, colourless bands; stem elongated, attenuated upwards,
whore it is curved, bright brown, expanding at the base into a
