One should take this with a grain of salt. First of all according to the article the authors of the paper themselves admit that they do not have conclusive evidence that the observed structures are actually mushrooms. And if you go through the paper everything you see just looks like pebbles.

And something else to consider are some of the other papers of the main author that suggest at least to me that they probably are not an expert in this field:

• Quantum Physics of God: How Consciousness Became the Universe and Created Itself
• Quantum Entanglement with the Future: Lincoln Dreams of His Assassination
• The Time Machine of Consciousness Quantum Physics and the Time Machine of Consciousness: Past Present Future Exist Simultaneously. Entanglement, Tachyons, Relative Time, Circle of Time, Quantum Time, Dream Time, PreCognition, Retrocausation, Deja Vu, and Premonitions
