"Showing One of the More Common Molds found on Fruits and Bread. The tiny stalks grow verticallyinto the air. The end of each thread swells into a small round knob, from the inside of which hundreds of minute bodies, called <em>spores</em>, burst. As <em>a</em> is seen a large knob filled with spores." — Blaisedell, 1904
