ONE of the commonest, and at the same time 

 most beautiful of our smaller fungi, Nectria 

 cinnabarina, presents itself under the appearance of 

 bright pink or coral-like pustules, about half the 



brown and wrinkled surface. Sometimes a pustule 

 may be met with presenting the characters of the two 

 apparently distinct plants, which are now known to 

 be conditions of one of the same plant. If a section

 branches ; this fungus illustrates the very common 

 phenomenon of dimorphism, or alternation of gene- 

 rations.* If a few twigs bearing this parasite be 

 examined the greater number of plants will probably 

 be more or less pink and perfectly smooth. Mixed 

 with these are sometimes a few of a deeper red or
