(i) Mycelium Mycelium is coenocytic and non-septate
or aseptate. Septa are formed only in connection with
separation of old senescent parts and delimitation of
reproductive structures.
(ii) Eucarpy and holocarpy In eucarpy, only a portion
of sornatic body is transformed into reproductive body.
In holocarpy, transformation of the whole somatic
body into reproductive structure is found in only some
primitive forms.
(iii) Asexual reproduction It involves the formation of
sporangia. The sporangia function as conidia in dry
habitats as zoosporangia under wet conditions.
