In article XII of this series the above genera were h'sted and 

 described in their proper order, but the species were omitted for 

 lack of space. The present paper deals with the published spe- 

 cies only of these three genera. 



BJERKANDERA Karst. Medd. Soc. Faun, et PL 



Fenn. 5 : 38. 1879 



Merisma Gill. Champ. Fr. i: ^'iZ. 1878. Not Merisma Per- 

 soon. 



Myriadopoms Peck, Bull, Torrey Club II : 2^. 1884. 



This genus was based on BJerkandera adusfa (Fr.) and six 

 other species, and described as f6llows ; 



** Receptaculum pileatum, sessile, carnoso-Ienlum, molle, elasticum, anoclermeum. 

 Pileus azonus. Hymenlum heterogeneura. Pori colorati, integrl." 



Merisma of Gillet was based on Merisma imberbc (Bull.) and 

 twelve other species. The name had been previously used by 

 different authors for groups of fungi in which the sporophore was 

 branched. Persoon used it for a group of the Clavariaceae. 



Myriadopoms of Peck was founded upon Myriadopoms adust us 

 Peck, which is only an abnormal form of BJerkandera adiista 

 (VVilld.) Karst., and hence a synonym.
