Don’t you think  
              It’s rather weird  
              To study  Usnea  
             Or Old Man’s Beard?  
                   Whose location, habits  
              And distribution  
              Would hardly start  
              A revolution.  
                   Yet otherwise  
              Intelligent folk  
              When faced with lichen  
               Drool – no joke!  
                   They’ve learned each genus  
              Has its brood  
              Of disputed categories  
              Strict or rude.  
                   But is it spatting  
              Over species  
              (Which do at times  
              resemble faeces)  
                   That fascinates  
              These rapt apologists  
              For fungi/alga:  
              Lichenologists?  
                   Or is it that  
              Famed symbiosis  
              (Which, some say, brings  
              Swift sclerosis  
                   To any grand  
              And rich synopsis  
              Of the world,  
              All for  Placopsis?)  
                   No! I cannot  
              Cop this schema  
              Those who ponder  
              O’er  Collerna,   | 
               Or decide which  
              One is hairier,  
              Neuropogon  
            Or Lobaria,  
                   Are the finest  
              Folk around  
              Noses always  
              On the ground  
                   Getting up to  
              Genetic tricks  
              With Relicina  
            or Bulbothrix  
                   While searching for  
                      Baeomyces’ thallus  
              Or even  
              Coccocarpia’s phallus…..  
                   Yet those untrained  
              In spotting lichens  
              See them more  
              As mould than icons.  
                   They realise not  
              The childlike glee  
              Felt at each  
              Discovery!  
                   Now, one solution  
              To this plight  
              Is to shine  
              A gaudier light;  
                   Lichenologists  
              Could do worse  
              Than pen their papers  
              In peppery verse.  
                   (With this final  
              Curt provisum  
              What the hell  
              Rhymes with Leptogium?)   |
