Abstract Chemical extraction procedures have shown that sporopollenin is a major component of the ascospore wall of Neurospora crassa and Neurospora tetrasperma. The sporopollenin is about 12% total dryweight of ascospores, and is localised in the ribbed perispore layer. Radioactive β-carotene is efficiently incorporated into the sporopollenin, and it is suggested that carotenoids are the natural precursors that are polymerised in the perispore. However, three carotenoid-deficient mutants of N. crassa produced perispores of normal appearance and properties.
