Remarks (internal):By the kindness of Dr M. H. Homrich, Porto Alegre, it has been possible to study two gatherings in her charge of this apparently endemic species, each a single fruit body preserved in spirit. ICN 6131 differs from Moller's description in having six columns united above into a ring perforated at the centre. This formation of a mesh approaches the receptacle of a Clathrus. ICN 6534 is said to have had a white receptacle, though all other material known is orange to yellow.
Superficially this species is very similar to Clathrus columnatus from which it is clearly separated by the peculiar glebiferous membranes. There is also a difference in colour, red to orange in C. columnatus, orange paling to yellow or white in B. rhacodes. It would appear from the illustrations and from the limited personal observations that the tubes of the receptacle are not as frequently intercommunicating and fenestrate as in C. columnatus and the arrangement of the tubes certainly appears much more regular.
A feature of this species regarded as primitive is the distribution of the gleba along the whole length of the columns. In this it is more primitive than C. columnatus. In the next species, B. angolensis, the gleba is restricted to the upper part. Another primitive feature is the massive construction of the receptacle, with its numerous large tubes.

Description:Blumenavia rhacodes A. Moller in Schimper, Bot. Mitt. a. d. Tropen 7: 57 (1895).
Laternea rhacodes (Moll.) Lloyd, Synops. Known Phall.: 50 (1909).
Egg cream to pale grey-brown, the outer surface sometimes cracking into angular brown scales, ellipsoid, up to about 3.5 x 3 cm, rooting by abundant thick mycelial strands, dehiscing by large irregular rents from the apex. There is a fairly thick gelatinous layer traversed by conspicuous peridial sutures corresponding to each column of the receptacle, immature glebal mass about 2 cm diameter, in large radially orientated blocks alternating with blocks of compressed receptacular tissue. Expanded receptacle 8.5-13 cm high and about 8 cm wide, clear orange to yellow above, paling to whitish below, occasionally completely white, ovoid to obovoid with from 3 to 6 robust columns, each up to about 1.5 cm diameter at the widest part, narrowing above where they are united, free below, with a median groove down the outer surface, fertile over most of their length. Sections of columns are triangular from the upper parts, becoming trapezoid lower down, and show a number of small tubes around the meso-abaxial groove, laterally and inwards from these are a few rather wide tubes, then the innermost tube is very large, V-shaped in section, surrounding the other tubes on the inner and lateral faces and incomplete at the point of the V. It tears along this line at maturity swinging outwards and forwards to form a ragged crest along the anterio-lateral angles of the column; this crest carries the gleba. Gleba restricted to the lacerate-dentate glebiferous crest, running virtually the whole length of the columns except where they are hidden in the volva, olive-brown, smelling of rotting fruit, finally nauseous. Spores 3-4 x 1-1.5 µm. Fig. 16.
Type locality: Blumenau, Santa Caterina, Brazil.
