Calicium is a genus of leprose lichens.[1]: 234  It is in the family Caliciaceae, and has 40 species.[2]

The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin (called a mazaedium), hence the common name pin lichen.[1]: 15  They are also commonly called stubble lichens.[1]: 234 

They have been used as indicator species for old growth redwood forests.[1]: 234
