Fruiting inside an old Adobe home

Linda Garvin emailed this inquiry:

A man brought these in the other day. They are growing in a closet where the roof is leaking.
It’s an old adobe home. He wants to rent the place and wanted to know if they are poisonous.

I told him he needed to fix the leak then the dark moist environment where the mushrooms are thriving would be eliminated and thus the mushrooms.

Any idea as to what they are? They are creamy to light yellow in color, the cap is about 2" across, and the stem 4" long
