Nice to know that you could confirm Laetiporus sulphureus is distributed ubiquitously in India.
I am only assuming that the photographed mushroom is a very young form of the mushroom.
Laetiporus sulphureus is mostly found associated with tree trunk which they eventually decompose.
Hence my speculation is completely based on probability , there is ever possibility that the fungus
which you have recorded may be something different.
