white in rotten wood. Sporangia subcylmdrical or ellipsoid, 
stipitate or nearly sessUe, crowded, 1 to 1-5 mm. high, 0-6 mm. 
broad, flesh-coloured, more rarely red; cup of sporangium^wa i 
membranous, even or interruptedly plicate, spmulose. Stalk 
weak, 0-1 to O'S mm. long, flesh-coloured, filled with spore-like 
cells.' Oapillitium a very loose elastic network of pale pmk 
threads, 3 to 5 diam., sparingly and somewhat irregularly 
branched, with here and there broad perforated or ring-like 
expansions, often swollen at the axils of the branches ; thickenings 
in the form of sharp cogs, half rings, or spines arranged as a 
border or in a loose spiral, and of minute scattered spinules ; free 
ends present, more or less numerous, clavate or pointed, spinose. 
Spores pale flesh-coloured, smooth or with a few scattered warts,

This species is closely allied to A. punicea, from which it is chiefly 
distinguished by the capilHtium having free ends and being without 
attachments to the cup, and by the more diffusely expanding net ; but 
intermediate forms are of not infrequent occurrence.

Sporangia cylindrical, stipitate, crowded, 1 to 1*5 mm. high, 
0*6 mm. broad, copper-coloured, or deep brown with a carmine 
tinge ; sporangium-wall irregularly evanescent above, the cup 
plaited and smooth below, papillose at the rim. Stalk cylindrical, 
0"5 to 1 mm. long, red-brown or brownish-black, filled with 
spore-Hke cells, and rising from a membranous hypothallus. 
CapUlitium an elastic network of freely branching red threads, 
2*5 to 3'5 fx. diam., marked with a border of broad-based spines

covered with minute spines in addition ; with many free clavate 
ends and few attachments to the cup. Spores pale red, smooth, 
or with few scattered warts, 6 to 8 /a diam. — Leangium stipatum
