Reproduction
Both
Sexual

- involves the union of two compatible nuclei

(karyogamy) followed by meiosis

- involves specialized structures and spores

Teleomorphic

Asexual

- an increase in the vegetative mass or the development

of asexual reproductive structures and spores

- no union of nuclei or gametes
