c. Resiipi)iate-effnsed, with a hyssinc border. 



4. M. HiMANTioiDES, Fr. Effused, bombycine, very soft, 

 fibrous-silky underneath ; the border byssine. Folds porose, then 

 gyrose ; dirty yellowish, then subolivaceous. 



On rotten wood of Beech; rare. The whole of a silken text- 

 ure, loosely adherent and variable in form; the margin loosely 

 tomentose. The folds at length poriform, crisp, flexuous; the color 

 gray, violaceous, olivaceous, dirty yellow, etc. 



5. M. MOLLUScus, Fr. Effused, thin, soft, membranaceous; 

 the margin byssine white. Folds porose-gyrose, flesh-color. 



On rotten wood of Sugar Maple; rare. Extensively effused 

 for several feet along the side and underneath a rotten log, form- 

 ing a soft loosely adhering membrane, the color fleshy or creamy- 

 white. The dried specimens are orange or brownish and the folds 

 in some places shrunken into ridges and tubercles. 



6. M. PORiNoiDEs, Fr. Crustaceous-adnate, thin; the border 

 byssine, white. Folds poriform, distant, dirty yellow. 



On rotten wood of Oak; rare. Effused to the extent of 2 or 

 3 inches, crustaceous, thin, persistent; younger specimens are all 

 villous and white; the pores are round or linear and flexuous. 



Genus VII. POROTHELIUM, Fr, 



The fungus composed wholly of the interwoven mycelium, 

 resupinate-expanded and submembranaceous; from which project 

 papillae at first distinct, soon porose-opened, at length elongated 

 and tubular. 



I. P. FiMiiRiATUM, Pers. Effused, membranaceous, tena- 

 cious, white; the border with a fringe of terete lacinia:;. Warts of 

 the pores hemispheric, superficial, at first and on the border dis- 

 tinct, afterward confluent in the middle. 



On the lower side of logs and wood of all sorts; connnon. 

 A very elegant fungus. Widely effused and membranaceous, with 

 a white fringed margin. The mass of the pores becomes crowded 

 and confluent, while only the marginal ones remain distant and 

 distinct; yet the hymenium never looks like that of a Polyporus. 



Genus VIII. SOLENIA, Hoffm. 



Receptacle none, tubules membranaceous, subcylindric, dis- 

 crete and free from each other; the mouth connivent. 



I. S. FAscicULATA, Pcrs. Grcgarious, subfasciculate, clava.te- 

 cylindric, somewhat silky, white.
