The sporocarps of this species also contain thiaminase, an enzyme that robs the body of vitamin B1. In small quantities this enzyme will do no harm to people eating an adequate diet that is rich in vitamin B, though large quantities can cause severe health problems. Fairly resistant to heat, the quantity of enzyme can be greatly reduced by thoroughly drying or cooking the plant[

Cultivation Details

We have very little information on this species, and do not know if it will be hardy when grown outdoors in Britain, though judging by the plants native range, there is a good chance that forms from the south of its range could prove hardy at least in the milder areas of Britain.
Most species produce sporocarps as their habitat dries. Spores of some species retain viability within the sporocarp for nearly 70 years; thus species can survive in areas of infrequent rainfall[

Propagation

Spores. The plant produces sporocarps, these need to be lightly abraded and then immersed in water. The sporocarps will then swell and burst to release the spores. The spores germinate immediately, the highly developed prothallus remains inside the large seed-like spores. The gametophyte generation is completed in 24 hours and the first roots and shoots appear in 2 - 3 days. Mature plants bearing sporocarps can develop in as little as 3 months[

Spore germination in the family occurs after rupture of the sporocarp wall allows the sporocarp contents to be hydrated. A gelatinous structure emerges from the sporocarp, breaking it into valves and carrying the sori into the water. Spore germination (gametophyte growth) and fertilization occur immediately[
