Remarks (internal):The possible record for Chile is that by Montagne (1850, 1854) as Laternea triscapa, the description and illustration both suggest B. angolensis in colour and habit but the structure of the glebifer is not indicated. Eichelbaum (1906) recorded a gathering of five fruit bodies from the Drakensberg Mts, South Africa and gave the spore size of fresh material as 6 x 2µmsconfirmed ay j separating the African d South AmericanIfthi fungiiscon as diffrmeerentit taxam butustify this is scarcely advisable in thane
present scanty state of our knowledge. Hennings (1902) gave a detailed description of the spirit material on which he founded B. usambarensis, noting the glebifer, `ramis ... albidis, intus lateraliter appendicibus membranaceis triquetris vel dentiformibus, interdum incisis, usque ad 5 mm diametro, glebam olivaceo-atram sustinentibus praeditis' and found spores 3-3.5 x 1.5 µm as in South America.
In Blumenavia angolensis the receptacular columns are less spongy-textured than in the previous species, as would be expected since the receptacle is much less massive and hence needs a more rigid type of construction to maintain the required degree of strength. It is the most regularly tubular member of the series but still less so than species in the Clathrelloid series of Clathrus. It also differs from B. rhacodes in restriction of the gleba to the upper part of the fruit body, in having a white receptacle and in lacking the groove along the middle of the outer side of each column. In sections of the immature receptacle the glebiferous wings can be seen to be developed from the sides of a large adaxial chamber the wall of which is specially thickened except on the adaxial side, where it is defective. At maturity it ruptures along this vertex and the thickened side walls are left free to fold sideways and forwards, as irregular flaps, carrying the greater part of the gleba with them. Thus in both species of Blumenavia the gleba comes to occupy a position lateral to the column at maturity, reminiscent of its position in Lysurus, though in that genus the displacement is achieved by other means. There appears to be a trend throughout the Clathraceae towards making the gleba more accessible by removing it from the interior of the fruit-body, either by fragmentation, opening at the apex and recurving of the arms, suspension from an apical glebifer exposed at the sides or transference to the sides of the arms.
The eggs of the American material are dark coloured, brown in Dennis' collection, almost black in Dring's, with the outer surface cracking into large scales to reveal the whitish tissue beneath. The sketch by Welwitsch in Herb. Currey (K) of the type of B. angolensis does not indicate a dark volva but that of B. usambarensis was evidently coloured: `volva ... extus pallida, subolivaceo maculata'.

Blumenavia usambarensis P. Hennings, Engler Bot. Jahrb. 33: 37 (1902).
Egg subglobose, up to 4 cm diameter, with longitudinal furrows corresponding to the peridial sutures, opening by a number of large, irregular, apical lobes. Receptacle white, long-ovoid, up to about 10 x 3 cm, consisting of from 3 to 5 unbranched columns, each up to 1 cm wide where it emerges from the volva, narrower above where they are united at the apex, free below, subtriangular or quadrangular in transverse section; tubes about six, somewhat irregular in shape and position, sometimes intercommunicating, innermost tube with a specially thickened wall except at the point nearest to the axis of the fruit-body, where it is absent. At maturity the two halves of this thickened wall swing outwards to form a pair of raggedly dentate glebiferous wings extending the whole length of the inner angle of the sides of the columns. Gleba of the usual type but restricted to the upper quarter or one third of the receptacle. Spores of the usual type, 3-3.5 x 1.5 µm. Fig. 15F - G.
