Comments

According to Walker (1971) the correct spelling is vuyckii, after the Dutch botanist Laurens Vuyck (1862–1931), although both specific epithets vuyckii and vuijckii are used in the literature. Hämet-Ahti (1982) first reported this smut fungus in Australia, and this also represented its first record for the Southern Hemisphere. Hämet-Ahti (1972) noted that the most distinctive symptoms were found in the anthers and ovaries. In particular, the anthers were unopened after anthesis, shorter but with longer filaments than healthy specimens, sterile and filled with conidia c. 2 × 1 µm.
