11. Most women with Ascus , or No . 2, results, are not developing cancer. 12. The ascus initial itself forms as a radiating spur branch at the top of the hook. 13. Initially about 3 ?m thick, the ascus walls thin to roughly 1 ?m when mature. 14. The zygote grows into the ascus , an elongated tube-shaped or cylinder-shaped capsule. 15. The spore dimensions are 32 43 by 25 38 asci contain 6 to 8 spores per ascus . 16. It counts with 8 spores per ascus , which are ellipsoid and measure between long and wide. 17. The spores, which number two ( more rarely three ) per ascus are characteristic for this species. 18. That means it can take over a year to be sure that an ASCUS result was a false alarm. 19. With no special mechanism, ascospores are all forcibly discharged from the ascus to sit on the leaf surface. 20. Large masses of yeast cells, asci or ascus -like cells, or conidia can also form macroscopic structures.
