The spores are released into the air when the mold is mechanically disturbed, particularly when wet. It is considered an uncommon contaminant of most indoor air. [12] Not all strains of S. chartarum produce mycotoxins, and under certain conditions some of these may gradually lose the ability to produce such toxins.
Rhizopus stolonifer is commonly known as black bread mold. [1] It is a member of Zygomycota and considered the most important species in the genus Rhizopus . [ 2 ] It is one of the most common fungi in the world and has a global distribution although it is most commonly found in tropical and subtropical regions. [ 3 ]
A printable chart to make a spore print and start identification. The spore print is the powdery deposit obtained by allowing spores of a fungal fruit body to fall onto a surface underneath. It is an important diagnostic character in most handbooks for identifying mushrooms. It shows the colour of the mushroom spores if viewed en masse. [1]
The most infamous species, Stachybotrys chartarum (previously known as Stachybotrys atra) and Stachybotrys chlorohalonata, are known as black mold or toxic black mold in the U.S., and are frequently associated with poor indoor air quality that arises after fungal growth on water-damaged building materials.

The sporangiospores are asexual mitospores (formed via mitosis), produced inside sporangia (thousands of spores) or sporangioles (single or few spores).They are released when mature by the disintegration of the sporangium wall, or as a whole sporangiole that separates from the sporangiophore.

"We don't recommend cutting mold off of bread, because it's a soft food," Marianne Gravely, a senior technical information specialist for the United States Department of Agriculture, told NPR ...
The spores are wind-dispersed and they are often extremely abundant in outdoor air. Indoors Cladosporium species may grow on surfaces when moisture is present. Cladosporium fulvum , cause of tomato leaf mould, has been an important genetic model, in that the genetics of host resistance are understood. [ 4 ]
