The fungus looks like a Xylaria species (Ascomycete), some species of which can cause white rots of hardwoods, but this photo looks very similar to Xylaria polymorpha, with the common name Dead man's fingers, which you can see at the link and photo provided. This particular fungus is a saprophyte that lives on dead wood in the soil. So, this fungus may not actually be growing on the living roots (causing a rot) as it may appear, but on dead wood of the root or in the adjacent soil.

UR Guess is correct sir...we r not observe this ?. characterstics. maybe it is dry rot..just we taken images...only. Thank u for clarification..i will try nxt time..plan to material collection...Thanking you.

I think it is Xylaria polymorpha (Dead Man's Fingers), Fruiting bodies
Alphus Dan wilson sir.
It is Xylaria polymorpha (Dead Man's Fingers), Thank you for Identification.
Dear Chennakesavulu Naik Mudavath
Based on your pictures the structures ( fruiting body) looks like stroma of Xylaria polymorpha, This species commonly known as dead man's fingers. It is a common inhabitant of forest and woodland areas, usually growing from the bases of rotting or injured tree stumps and decaying wood. Xylaria causes a white rot of wood, decomposing both lignin and cellulose. In fact the fruit bodies can attached to a wood substrate underground but appear on the soil. By the way you can prepare a cross section of the stromatic structures for observation of the peritheciums.
Regards
What is the purpose of knowing, only name. It holds good for a angiospermic or gymnospermic taxon. In case of microbes, identification can not be by ocular morphology. it is better to restrict only fungal fruiting body. for further you need to follow microscopic study. Xylaria polymorpha may be correct but need to establish by systematics.
Dear Chennakesavulu;
It is unmature stromata of the genus Xylaria. For morphological identification of the fungus you must wait for maturation of the stromata and check its mature stromata (such as shape, size, width, surface, tip and ...) and ascospore (such as shape, size, germ slit and ...) and comparing it with relevant literature of key to species of the genus Xylaria.
