1 Alternaria
2 Colletotrichum

Which group of fungi is commonly known as imperfect fungi?
1 Phycomycetes
2 Ascomycetes
3 Basidiomycetes
4 Deuteromycetes
Explanation:
(d) Deuteromycetes is commonly known as fungi imperfecti due to absence of perfect sexual stage. They are classed by the colour and structure of the conidia. Since most of the conidia structures look like ascomycetes type, they are believed to be derived from. ascos which does not have the ability to reproduce sexually.

Dikaryon formation is the characteristic feature of
1 ascomycetes and basidiomycetes.
2 phycomycetes and basidiomycetes.
3 ascomycetes andphycomycetes.
4 phycomycetes and zygomycetes.
Explanation:
(a) In fungi (ascomycetes and basidiomycetes), kayrogamy is delayed and occurs just before meiosis. In the stage intervening between plasmogamy and karyogamy the cells often contain two nuclei or dikaryons $\left( n+n \right)$. Such cells are calied dikaryotic cells. The phase is known as dikaryophase.
