Novel mechanism of spermatization
- S. T. TILAK
The fungus genus Sphaerostilbe was erected by TULASNE (1865) with Sphaerostilbe/lammea as the type species. The genus is widely distributed in the tropics and is an important pathogen of Tea where it causes red root rot of Tea and other crops. Some species have been reported on scale insects. The development of ascocarp by VINCENS (1917) and LUTTRELL (1944) definitely suggests the perithecial nature of ascocarp and presence of pseudoparaphysis. However, no report has been made about the occurrence of spermogonial bodies in this genus. Since the classical researches of HIGGINS (1920, 1929, 1936) on the occurrence of these bodies and their function in initiation of spermatization, several workers have confirmed their occurrence and function in different genera of Ascomycetes. However there is no report about the occurrence of spermogonia in this genus. I t is presented as new to science on comparative morphological studies and host specificity.
