Which one of the following matches is correct?
| Phytophthora | Aseptate mycelium | Basidiomycetes |
| Alternaria | Sexual reproduction | Deuteromycetes |
| Mucor | Reproduction by conjugation | Asocmycetes |
| Mucor | Reproduction by conjugation | Asocmycetes |
B.
| Alternaria | Sexual reproduction | Deuteromycetes |
(i) Phytophthora belongs to Phycomycetes (algal fungi). They contain either unicellular thallus or non-separate coenocytic mycelium. They are mostly plant damaging Oomycetes (water molds).
(ii) Alternaria is Deuteromycetes (fungi imperfecti), which lacks sexual reproduction.
(iii) Mucor also belong to Phycomycetes. They have mycelium which is coenocytic (multinucleate) and profusely branched. They reproduce vegetatively via conjugation.
(iv) Agaricus belongs to Basidiomycetes (where karyogamy and meiosis occur). They contain well-developed filaments, branched and septate mycelium. They are saprophytic but parasitic.
So, hence (b) option is correctly matched.
