A) Aspergillus
B) Albugo
C) Penicillium
D) Erysiphe
Correct Answer: B
Solution :
The mycelium of Albugo consists of branched, aseptate, coenocytic hyphae. The hyphae live and ramify in the-intercellular spaces of the susceptible host tissue, which produce intracellular haustoria in the mesophyll cells of the host. Aspergillus is a saprophytic fungus. The mycelium is well developed and made up of a loosely interwoven mass of hyaline bright or pale coloured, extensively branched, septate hyphae. Under certain conditions the mycelium develops into a sclerotium. The mycelium of Penicillium is well developed and copiously branched. It is composed of colourless slender, tubular, branched and septate hyphae. Baker (1944) observed anastomosing between hyphae of two mycelia resulting in a heterokaryotic mycelium. The mycelium of Erysiphe is known as ectomycelium. It consists of hyaline branched septate hyphae. The septa between the cells have each a central pore.
