Well-done!
Great photo and clear labelling.

How can you be sure it is "Phallus indusiatus"? Members under the same genus may look very similar.

Most fungi disperse their spores via ejection from the fruiting body, allowing them to travel by air to other places. The stinkhorn, however, relies on insects for spore dispersal! The ridged surface of the cap covered in brown spore-containing substance called gleba, giving off the stench of rotting flesh. It attract insects and flies to consume the slime and disperse the spores through defecation. Usually, by the time the fruiting body begins to wilt, all the slime has been consumed, leaving a white, exposed cap, just like the stinkhorn showing here.

To identify stinkhorn, we can check whether there is a delicate lacy skirt-like veil that hangs down below the cap.
