its apex. Spores oblong, curved, producing on germination a 

 branched promycelium bearing several strongly curved sporidiola. 

 (Fig. 112.) 



A genus of fungi greatly resembling Stereum in habit, and 

 perhaps more nearly allied to the Thelephoracea than the Tremel-

linacea ; the fructification is, however, very different from that of 

 Thelephora, while the strigose cartilaginous pileus differs from typical 

 Tremellinacecz. The next genus Hirncola is clearly allied to Auricularia 

 in habit, substance and fructification. Species 2001, 2002 



2001. A. mesenteriea Pers. (from a fancied resemblance to the 



mesenteric membrane) a b c. 



P. resupinate, then reflexed, entire or slightly lobed, villous, 

 yellowish, often green at base from algal growths ; z. brownish. 

 Hym. costato-plicate, brownish-violet, livid-purple or grey-liver. 



Taste insipid ; odour none. Trunks, stumps, beech, elm, walnut, vine, 

 chestnut, furze, broom, yew ; frequent. Jan.-Nov. 8 in. Sometimes 

 terrestrial, springing from buried wood, and then sometimes not unlike 

 Sticta pulmonaria in appearance. 



2002. A. lobata Sommerf. (from the lobed pileus) a b c. 



P. effuso-reflexed, much lobed, strigose or velvety, warm yellowish- 

 brown; z. darker, often green at base from algal growths. 

 Hym. broadly reticulate -ribbed, fuscous-livid. 



Bark of trees, elm ; not uncommon. 4 in. Closely allied to, if not 

 identical with the last ; the fruit is the same.
