|Major Groups > Stinkhorns > Blumenavia angolensis|
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.
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.
