Pankaj: yes thank you, truly... it answers the curiosity for a while... but if I sit down to ask really scientifically tough question it would take a lot of time and may be bore the other members...
being a physician, I learnt to look at fungi as opportunistic infectious agents... that if given a chance would kill.like the aspergilous in lung or brain or histoplasmosis ... etc.. and then there is candida.. a boon to the modern drug industry... we are always primed to kill fungi as soon as we see them... BUT but trying to sprout banana seeds in my cold nyc apt I needed to wait till some airborne fungi took pity on my seeds in the bottle on a wet gauze and coated them with their slimy growth , and then my seeds sprouted... I developed a sort of fondness for them...
