  
      Argyrochosma jonesii (Jones' lipfern, formerly Notholaena j.) is rare in IFNM, where it is near the southern limit of its distribution. | 
        
          Astrolepis cochisensis (left) and A. sinuata are common and widespread in the desert. They were formerly in the genus Notholaena. A. cochisensis is usually found on lime-rich soils. | 
    
    
        
        Cheilanthes pringlei (Pringle lipfern) was a candidate endangered species, but was rejected when it was found to be common in the Tucson Mountains and Sonora.  | 
        
        Cheilanthes yavapensis (Yavapai lipfern) is a recently described species commonly confused with C. wootonii.  | 
    
    
        
        Cheilanthes wrightii (Wright lipfern)  | 
        
        Notholaena standleyi (Standley cloakfern) is about as common and widespread as Astrolepis. | 
    
        
        Pellaea truncata (cliff brake) is widespread. | 
        
        Pentagramma triangularis (golden fern, formerly Pityrogramma t.) is widespread.     | 
    
        
        Most mushrooms are delicate and ephemeral, but this desert mushroom dries to a woody consistency and persists for a year or more.  | 
        
        Biological soil crusts (cryptogamic crusts) are important components of arid ecosystems. See the caption under soil crusts.  | 
    
    
        
        Lichens are actually not plants. They  are a symbiotic pairing between an alga and a fungus or a cyanobacterium. All three types of organisms belong to different kingdoms. This community of several species of lichens is in the Sawtooth Mountains. |
