Phycomycetes

Phycomycetes is an obsolete[1][2][3] polyphyletic taxon for certain fungi with aseptate hyphae.

[5] Asexual reproduction takes place by zoospores (motile) or by Aplanospores (non-motile).

These gametes are similar in morphology (isogamous) or dissimilar (anisogamous or oogamous).

The class Phycomycetes has been abolished and in its place exists Zygomycetes, Chytridiomycetes, Plasmodiophoromycetes, Hyphochytridiomycetes, Trichomycetes (including Harpellales, Asellariales, Eccrinales and Amoebidiales) and Oomycetes.

The members of this group are found in aquatic habitats and on decaying wood in moist and damp places or as obligate parasites on plants.
