256 OUTLIXES OF BRITISH FUNGOLOGY. 



On (lead wood. Rare. Twycross, Rev. A. Bloxam. Not 

 separable, like M. corium. 



7. M. pallens, B. ; adnatc, thin, inseparable, pale-reddish, 

 flesliy, subgelatinous ; folds poriform ; margin indeterminate. 

 — Ann. of Nat. Hist. ser. 1. vol. vi. p. 358. 



On fir-wood. Hare. Nottingliamsliirc and Leicestershire. 

 Pores minute. 



8. M. Carmichaelianus, B. ; white, extremely thin, form- 

 ing efiFused, entirely resupinate, irregular, interrupted, con- 

 fluent patches; folds forming regular angular reticulations; 

 dull brown when dry. — Grev. t. 22^. 



On bark. Very rare. Appin, Capt. Carmichael. Forming 

 a mere pellicle, with minute, often hexagonal, extremely shal- 

 low pores. 



9. M. lacrymans, Fr. ; large, fleshy but spongy, moist, 

 ferruginous-yellow, arachnoid and velvety beneath; margin 

 tomentose, white; folds ample, porous, and gyroso-dentate. 

 (Plate 2, fig. \.)—Hiiss. i. t. 3. 



In cellars and hollow trees. Too common. Often dripping 

 with moisture. Sometimes several feet in width. I do not 

 consider M. imlverulentus more than a mere form of the same 

 thing. Dry Rot is caused mainly by this fungus. 



10. M. aurantiacus, Klotzsch ; pilous tough, carnoso-co- 

 riaceous, effuso-reflexed, zoned, tomentose, between yellow and 

 dirty-white, here and there cinereous; folds minute, subpori- 

 form, dull-orange. 



On dead beech-trees. Rare. Scotland, Klotzsch. Allied 

 to the last. 



24. POROTHELIUM, Fr. 



Ilymenophorum mycclioid, covered with distinct papilhc, at 

 first closed, then open like pores.
