Identify the group of fungi that is not correctly matched with all the characters given below:

1. Phycomycetes:   Mycelium – aseptate and coenocytic / Asexual reproduction by motile zoospores or by nonmotile aplanospores / spores – endogenously produced in the sporangium
2. Ascomycetes: Mycelium – unbranched and septate / Asexual spores are conidia / Conidia produced endogenously on conidiophores.
3. Basidiomycetes:   Mycelium–branched and septate / Asexual spores are generally not found.
4.   Deuteromycetes:  Only the asexual or vegetative phase of these fungi are known.
