1920] The Lower Basidiomycetes of North Carolina 151 



The following- are translations of Sehweinitz's original descriptions 

 of species of Exidia and Tremella with notes added by us : 



Exidia lurida Schw. (No. 1100. Syn. Fung. Amer. Bor p: 185: 1832) "Effused 

 gyrose-plieate, pale, circular; rather thick. Shrunken on drying. Dotted over 

 Avith a few papillae. It occurs here and there on branches of Celastrus, Beth- 

 lehem. ' ' A plant in the Schweinitz Herbarium has the general aspect of E. 

 gelatinosa but seems different in tiie absence of scurfy particles. A preparation 

 showed basidia of the Exidia type. 



Exidia spiculata Schw. (No. 1101. Syn. Fung. Amer. Bor. p. 185:) "Adpressed, 

 effused, thick-lobed, rough, wrinkled, olivaceous-green, very slightly shrunken 

 on drying, but black in color. Papillae frequent on the upper side; margin 

 divided into small obtuse lobes. Bather rare on the cut surface of trunks 

 of Platanus, Bethlehem." On examination the type showed no papillae when 

 wet ; dark, effused, crumpled, extensive. Not shrunken to a membrane. A 

 slide revealed no facts of value. 



Exidia applanata Schw. (No. 1102. Syn. Fung. Amer. Bor. p. 185.) "Applanate- 

 expanded, closely adpressed, margin at length subfree, oblong in shape, mod- 

 erately thick, 2-3 lines long; drying black and somewhat pulverulent-scurfy; 

 marked on the surface with a few wrinkles or veins. Papillae scattered. On 

 the inner bark of Rhus glabra, Bethlehem." This may be E. gJandulosa but 

 a slide from the type shoAved no characters of value. 



Tremella crenata Schw. (No. 1141. Byn. Fung. Car. Sup. p. 89: 1822). "Rather 

 large, thick, wavy-applanate, ribbed, fuscous brown; margin beautifully crenate. 

 Occasional on branches." This is E. gelatinosa. 



Tremella crassiloba Schw. (No. 1112. Syn. Fung. Amer. Bor. p. 185.) "Erum- 

 pent, firm, with thick, fleshy-tremellose, rounded white lobes forming a globose 

 mass. In the wet state, surface apparently squamulose ; when dry, black and 

 pulverulent. Bursting forth from fallen branches, Bethlehem. ' ' A specimen 

 in the Schweinitz Herbarium shows low, black, pulvinate, somewhat uneven 

 warts about 1-1.5 mm. broad, coming through small holes in the bark of decid- 

 uous branches; when wet becoming murky clay-color and gelatinous, about 

 consistency of Exidia glandtdosa but does not seem to be that or E. recisa. 

 There are no papillae and the surface is not obviously granulose. Basidia sub- 

 spheriea.1, 4-celled, 11-13(U in diameter. 



Tremella corrugata Schw. (No. 1113. Syn. Fung. Amer. Bor. p. 185.) "Cespi- 

 tose, corrugated, with rather thin, flabby lobes, margin elevated, veiny; black- 

 ish-purple in color. Sub-squamulosc in the dry state. An inch in diameter. 

 Rare on Avood and liranches, Bethlehem." This is Exidia gelatinosa. 



Tremella palmata Schw. (No. 1117. Syn. Fung. Amer. Bor. p. 186.) "Rooted, 

 penetrating the wood with a tomentosc root. Stem compressed; palmately ex- 

 panded, horny when dry, of elegant golden color, sub-diaphanous, apex capitu- 

 late, gyrose-plieate, compressed and dilated; the head conlluent witli tlie stem. 

 In form and habit related to Cantharcllus spathularia, n. 292, on dead wood, 

 Bethlehem." This looks much like TUtiola radieata from the specimen in the 

 Schweinitz Herliariiim, but T (•()ul<l get very little from a preparation made 

 from it.
