11. Ceratobasidiaceae have aseptate basidia, but the sterigmata are quite large and irregular and the spores are self-replicating. 12. The basidia ( spore-bearing cells ) deflate after ejecting their attached spores, and no sterigmata were detected. 13. In some Basidiomycota the spores are not ballistic, and the sterigmata may be straight, reduced to stubbs, or absent. 14. They have eight sterigmata ( slender extensions that attach to the spores ), as well as a clamp at their base. 15. For example, Dacrymycetaceae possess very large and irregularly shaped sterigmata as well as self-replicating spores, but have aseptate basidia. 16. The spores are attached to the end of the basidia by four projections called sterigmata that are 1 3.5 �m long. 17. Eventually, from the stomata, hyphae extend out and elongate, branching into sterigmata or conidiophores ( spore-bearing structures ). 18. They measure 14 to 22 by 3.5 to 5 ?m, and each sport four " curved and remarkably thin " sterigmata . 19. The sterigmata are formed on the basidium as it develops and undergoes meiosis, to result in the production of ( typically ) four nuclei. 20. Basidia ( spore-bearing cells ) are club-shaped with two to four sterigmata , and measure 15 20 by 5 8 �m.
