TREMELLODON 



Cap fan-like, or incompletely funnel-form, more or less stalked, soft, jelly-like, 

 the lower or spore-bearing surface consisting of teeth. This fungus will be sought 

 first among the tooth fungi, but its texture and structural characters place it among 

 the jelly fungi. The name refers to the gelatinous texture and the teeth. 



Tremellodon gelatinosus Jelly Spine 



../ 



Cap 2-8 cm. wide, more or less clear, with bluisli tinge, roughened with small 

 ■dots, jelly-like, trembling, usually fan-shaped, somewhat stalked ; teeth soft, white ; 

 spores globoid, clear, 7-8/x. The name refers to the jelly-like texture. 



On decaving wood, autumn and winter : said to be delicious when slowlv stewed. 



HIRNEOLA 



Cap mure or less cup-shaped or ear-like, jelly-like but firm when wet, horny 

 when dry, the hpiienium often veined or folded, but without teeth. The name refers 

 to the cup-like form.
