Family Clathraceae 



FAMILY CLATHRACEAE 



The members of the family Clathraceae have a volva similar 

 to the volva of the Phallacece. The volva ruptures, and the 

 receptacle issues in a similar manner. The members of this 

 family have the spore receptacle latticed or branched instead of 

 tubular or cylindrical, and bear the spores on the inner surface 

 of the receptacle rather than on the outer surf:ice. 



Latticed Clathrus 



Clathnis cancellatus 



Receptacle not stalked. The 

 bars of the lattice-work are ob- 

 lique and transversely wrinkled. 

 The outer surfiice may be cinna- 

 bar red or white or yellowish. 

 The inner surface of the bars is 

 red.

Arms 



Stalk 



Volva 



Anthurus borealis 



Receptacle stalked, hollow, divided above 

 into arms, which do not join at their apices, and 

 which bear the spore masses on their inner sur- 

 faces, enclosing the spore mass when young, 

 but later diverging. 



Stem of receptacle white ; arms narrow 

 lance-shaped, with pale flesh-coloured backs, 

 traversed their entire length by a shallow 

 furrow.
