Thanks for all the information Kiran Srivastava added some more interesting information which he got from a photograph that he had posted earlier
'Some fungus have a mycorrhizal relationship with trees. This special relationship means that the fungus wraps its mycelia around tree roots. The fungus then gives the tree special nutrients from the soil that it couldn’t get by itself. This helps the tree stay healthy and strong. In return, the fungus can pull different nutrients from the tree roots that it would not get on its own. Therefore the fungus and tree help each other. Mycelia: The vegetative part of a fungus, consisting of a mass of branching, threadlike hyphae. Mycorrhizal relationship is same as symbiotic relationship i.e., Like we see between Langurs and Chital deer.' Sindhu Ramchandran from Pune replied thus: Good Info..the photo you have posted is of cauliflower mushroom. Ecology: growing from the roots or bases of trees; Sparassis (also known as cauliflower mushrooms) is a genus of parasitic mushrooms characterised by their unique look. Its look can be described as similar to a sea sponge, a brain, or a head of cauliflower, from which it has been given its popular name. regards mohina
