•The specimens of Lentinus chrysopeplus reported in Bulletin No. 3 have since been 

 compared with Berkley and Curtis's type specimens in the Cryptogamic Herbarium of 

 Harvard University, and are evidently very dififerent. The specimens previously 

 reported were evidently Dr. Peck's Omphalia scabriuscula. In regard to this species, 

 Dr. Peck writes as follows: "I received from you this morning the specimens of a smal^ 

 yellow mushroom. I have compared them with our specimens of Omphalia scabrius- 

 cula, a.nd I find no essential difference. Yours are a little smaller. I think them the 

 same species."
