Exidia.] FUNGI. 217 



with my plant, as does the figure of the sporidia. I have once seen 

 specimens of a small white opaque nucleus at the base, exactly as in 

 Ncematelia nucleata. All the specimens, however, on the stick had 

 not the nucleus, and similar bodies are sometimes found inunersed in 

 other parts of the frond. I do not find these to consist of masses of 

 sporidia, as figured, possibly by some mistake, by Sowerby.

 clustered twisted tumid brown shining and gelatinous, when 

 dry thin and membranous." Eng. Bot. t. 1^70. With, v, 4.

On beech-wood. St. Leonard's forest, Sussex, Mr. Borrer. Car- 

 niyle, Hophirk. — " In perfection in very wet weather only, when it 

 forms numerous soft and pulpy clusters, twisted and tumid like the in- 

 testines of some animal, of a darkish dull brown, but with a shining 

 surface, obscurely dotted. Inside paler and almost white, except that 

 when cut longitudinally brown vertical streaks are discernible near the 

 surface." Sm. I. c. I am inclined to think that this is one of the various 

 forms oi Exidia glandulosa. At least I have found on a felled decor- 

 ticated oak, a production so similar, that 1 cannot but think it identical, 

 uhich I am pretty certain is a barren or immature form of that plant. It 

 differs only from the figure and description in Eur/. But. in being of a 

 deep cinereous tinge, verging upon black. 



8. T. sarcoides, With. {fiesh-Hke TremeUa) ; clustered soft 

 viscid of a purplish flesli-colour at first clavate, at length com- 

 pressed lobed and plicate. With. v. 4. p. 68. Eng. Bot. t. 

 2450. Furt. v. 2. n. 885 {in part). Fr. Sijst. Mtjc. v. 2. p.

2.— r. amethijstca, Bidl. t. 499./. 5. 



On stumps of trees, &c. Winter ; frequent—Distinguishable at once 

 on analysis from Bidgaria sarcoides, by its minute oblong and some- 

 tin)es curved, free sporidia. T. amtthystea, With., though some of 

 the synonyms belong to the present species, is apparently B. sarcoides, 



9. T. clavdta, Pers. {chih-shaped TremeUa) ; solitary simplff, 

 apex incrassated flesh-coloured inclining to red, base blackish. 

 Fers. Ic. pict. t. 10./. 2. Fr. Syst. j\Iyc. v. 2. p. 218. 



On rotten wood. Appin, Capt. Carmic/iaet.— Xhout 1 inch high. 

 2 lines broad, blackish below and slightly twisted. Capt. Carniichaers 

 specimens exactly correspond with Persoon's figure, but 1 am doubtful 

 whether his plant is entitled to rank as a species. 



38. Exidia. Fr. Exidia. 



Fcccptaclc gelatinous, homogeneous, covered above only with 

 the papillate* hymcnium. Sporidia at length bursting forth 

 €'lastically. — Named from cxudo, to exude. 



1. E. Auricula Judtc, Linn. (Jew's Ears) ; sessile concave 

 flexuous venoso-plicate w ithout and within, beneatli subtomen- 

 tose olive-cinereous. Fr. Syst. Nye. v. 2. p. 221. Moug. ^■
