by Michael Kuo
Originally described from Angola, this interesting stinkhorn began to be documented in the Houston, Texas area in the early nineties; it may have been introduced through Houston shipping from the Caribbean, South America, or Africa. On casual inspection it looks like a white version of Clathrus columnatus, but its spore slime is produced in conspicuous membranous "glebifers" that are attached to the inner surfaces of the arms.
Thanks to Tom Taroni for collecting, documenting, and preserving Blumenavia angolensis for study; his collection is deposited in The Herbarium of Michael Kuo.
Ecology: Saprobic; growing alone or gregariously--often near stumps or woody debris; Texas, the Caribbean, South America, and Africa; fruiting nearly year-round.
Fruiting Body: When young appearing like a whitish to brown or black "egg," but soon "hatching" and developing into a cage-like structure measuring up to 10 cm high and 4 cm wide; oval in shape, composed of 3-5 unbranched, white arms that are joined at the top; arms about 1-1.5 cm wide, in cross-section more or less triangular or four-sided, with the outer surface fairly flat (lacking a pronounced longitudinal groove) and the inner surfaces more rough, punctuated by membranous flaps of tissue; the edges between outer and inner surfaces often appearing jagged or "toothed"; spore slime dark brown, produced on the flaps on the inner surfaces of the arms over roughly the top half of the structure; bases of arms free, but encased in a whitish to dark gray, dark brown, or nearly black volva; base attached to prominent white rhizoids.
Microscopic Features: Spores 3-4 x 1-1.5 µ; cylindric; smooth; hyaline in KOH.
