HEMI-BASIDIOMYCETES 



'Jew's Ears' Fungus 

 (^Hirneola auricula-judae^ Berk.) 



Enumerated by Prillieux and Delacroix {Bull, du Minis- 

 tere de rAgric, xii.. No. 5, Sept. 1893) as a wound-parasite, 

 attacking the mulberry-tree. 



The fungus is very thin, and flexible like indiarubber, 

 more or less shaped like a human ear, flesh-coloured or lurid, 

 the sterile side minutely velvety. Common in Britain on 

 living branches of elder {Saf/ibuais nigra), which it kills.
