AUIIICULAHINI. 269 



On tl)C ground, in woods. Not uncommon. Bristol. 

 Northamptonshire. The hymenium, with its quaternate 

 spores, is a pretty, opaque object under the microscope. 



13. T. byssoides, P. ; irregularly effused, at first byssoid, 

 ochraceous-white, then compact and fleshy, pulverulent, fer- 

 ruginous-yellow ; eircumfereuce byssoid, nearly white. 



On the ground, especially amongst fir-lcavcs, making patches 

 a foot broad. Not uncommon. The ferruginous spores at 

 once separate this from every form of T. mollissima. 



14. T. puteana, Schum.; roundish and effused, fleshy, rather 

 thick, brittle, yellowish, then tawny-olive, at last brownish- 

 olive, dusted with the spores; circumference muccdinous, white; 

 hymenium somewhat undulated. 



On stumps, wood in cellars, etc. Not uncommon. Some- 

 times dripping with moisture. Occasionally large, globular, 

 solid or hollow lumps, are formed upon the hymenium, giving 

 the plant a very singular appearance. 



15. T. laxa, Fr. ; membranaceous, soft, loosely adherent, 

 arachnoid beneath, white as well as the byssoid circumference ; 

 hymenium papillose, pallid, then ferruginous-olive, dusted with 

 the ferruginous spores. 



On lichens, moss, etc. Rare. King's Cliffc. Oswestry, 

 Rev. T. Sahvey. 



1 6. T. arida, Fr. ; membranaceous, soft, arachnoid beneath, 

 and white as well as the byssoid circumference; hymenium 

 papillose, pallid, then ferruginous-olive. 



On decayed pine-wood, in cellars and woods. Common. 

 Not so thick as T. puteana. 



17. T. olivacea, Fi\; membranaceous, effused, adnate; cir- 

 cumference white, fimbriated ; hymenium dull-olive, sctuloso- 

 tomentose. 



On pine-wood, Northamptonshire, etc. Probably common. 

 I have authentic specimens of this species from Fries.
