 reflexed, entire, villous, fasciato-zoned. Hymeniumcostato-plicate, 



fuscous-violaceous. 



On stems of trees. Frequent. 



5-7.5 cent. (2-3 in. ) broad, gelatinous in 

 wet weather, hard and cartilaginous when 

 dry, reviving with wet. Hymenium pow- 

 dered with a beautiful bloom. M.J.B.

2. A. lobata Sommerf. — As much 

 as 17.5 cent. (7 in.) long, 5-12.5 cent. 

 (2-5 in.) broad, 2-4 mm. (1-2 lin.) 

 thick. Pileus fuscous - whitish, ef- 

 fuso-reflexed, lobed, variegated with 

 strigoso - tomentose, velvety and 

 smooth zones. Hymenium fuscous- 

 livid, reticulato-ribbed with distant folds.

LXXXVII. Auric7tlaria mesen- 

 terica. One-third natural size. 



Corticium. Genus XLVIII. — Corticium {cortex, bark). Fr. Epicr. p. 556. 



Hymenium amphigenous, even or tubercular, springing imme- 

 diately from the mycelium without an intermediate stratum; in 

 typical species fertile and swelling when moist, fleshy-soft, con- 

 tracted and hence commonly cracked when dry, or the whole 

 breaking up. There are other species added to the genus with 

 the hymenium arid and incrusting. Sporophores 4-spored, rarely 

 single-spored. Resupinate, growing on wood, often sterile. Fr. 

 Hym. Eur. p. 646. 



I. Lomantia (A.w/xa, a fringe). Resupinate, but free at the circumference, 

 determinate, marginate, commonly cup-shaped then expanded. 



II. Himanti^s (tftas, a strap). Resupinate, effused, immarginate, clothed 

 with flaxy fibrils or strigosely hairy at the circumference and beneath. Often 

 sterile, fibrillose (mycelia). In their perfect state they are furnished with a 

 remarkably well developed, waxy -soft hymenium.
