WebThe chlamydospore has been defined as a thick-walled, non-deciduous, intercalary or terminal, asexual spore formed by the rounding of a cell or cells (Ainsworth 1971 ). The asexual nature of the chlamydospore distinguishes it from the teliospore of the Leucosporidiales, Sporidiales and Ustilaginales from which the basidium is produced. WebThe haploid nuclei that result from meiosis are generally incorporated in spores called meiospores. Fungi employ a variety of methods to bring together two compatible haploid nuclei (plasmogamy). Some produce specialized sex cells ( gametes) that are released from differentiated sex organs called gametangia.
