Cythium : it is a parasitic oomycetes. It causes damping of disease in the seedling of tomato, chillies and mustard.
Puccinia : Puccinia is heteroecious obligate parasite which completes its life cycle on two hosts; Primary host-wheat Secondary or alternate host-basberry It has macrocyclic life cycle with five types of spores: uredospores (n + n), teleutospores (n+ n) on wheat plant, basidiospore (n) in soil, pycniospores (n) and aeciospores (n + n) on barberry leaf.
Hence, the correct answer is option (D)
Note: Basidiomycetes are the most advanced and most commonly seen fungi. They are among the best three composers of the wood. They are able to decompose both cellulose and lignin. Lignin is not metabolised by any other kind of fungi, and not even by the bacteria, only these Fungi are responsible for the decomposition of the Lignin.
