Hi Ammar,

Yes, people already grow edible mushroom on compost with some animal manure (dung) or animal wastes. See the paragraph and photos of "Growing Agaricus bisporus" on this website: http://www.botany.hawaii.edu/faculty/wong/BOT135/Lect020.htm

Attached is a picture of the Common Mushroom (Scientific name: Agaricus bisporus.)

Yes! They grow well in animal stools. This is the reason, Indian call them Gobbar-Chattah (Gobar meaning animal stool and Chattah meaning Umbrella like structure)

For identification, refer the link below

I have  questions to the post Dr. Ammar Bader

(1) What is the temperature of  growth for all the above shown Mushroom

 (2) Any humidity in the environment other than the substrate.

  (3) Are these mushrooms seasonal

  (4) Is that  place a camel farm or camel migrants  

I would like to thank all contributors,

for Dr Anish Joseph: Makkah is one of the hottest places in the world, the temperature now in December  is 28-33 C°in the day and 22-25 C° in the night, the temperasture can reach to 52 C° in the summer, the environment is dry but recently the we got the rain, I do not know if these mushrooms are seasonal, but I have seen them for the first time. the camel are migrants, but they pass frequently in this place.

As many other organisms   , the  mushroom requires a  sources of  high nitrogen and water contents  for nutrition and growth and the animal manures specially in desert districts  is the good  the only available source for their requirement .   

Please note that Korea newspaper article below. I hope this helps.

"Mushroom that grows in sand unrecorded two species, the nation's first discovery."

The first two photos appear to be Montagnea arenaria.  The last two I'm not certain, but likely another gasteromycete.  Neither are likely associated with camel dung in this case, though there are many fungi which do occur, exclusively, on dung.  The fungi pictured here are typical for desert habitats.  I would encourage you to upload each set of images (separately) to Mushroom Observer, with as high of resolution images as possible, where a more confident ID may be obtained.
