a distance of 15 em. ; individual plates are centrally attached and 

 spread out flat on the bark, about 5-10 mm. broad and 1.5-2 mm. 

 thick except where crumpled by pressure, then at times up to 6 cm. 

 high, with much the habit of larger masses of Naematelia; at first 

 firmly gelatinous then softer on exposvire ; color amber to pale amber, 

 with a faint olive tint, later with brownish red tints in parts ; not root- 

 ing; surface glabrous, not glaucous. 



Spores (of No. 4070) elliptic, smooth, light greenish-yellow under 

 microscope, 6-7.4 x 9.3-12.9/^. Basidia oval, 12.5-14 x 15-16;a, four- 

 parted. 



That this is T. virens seems certain. It is different from anything 

 else we have, grows on dogwood and, in large groups, always shows 

 a distinctly greenish tint. It is not confined to dogwood, but is 

 also found on oak. Tremella virescens Schumacher (Enum. Plant. 

 Sfell. 2:439. 1803) does not seem very different as understood by 

 Brefeld. He was confused on the name of the last and treats it as 

 "T. virescens n. sp. formerly Naematelia virescens Schm." (Bre- 

 feld I.e. p. 128, PI. 8, figs. 25-28). Naematelia virescens (Schm.) 

 Corda is supposed to be the same, but Corda speaks of the inside veined 

 with white and figures the center pale (Icon. Fung. 3 :35, PL 6, fig. 90. 

 1839). The spores of T. virescens are given by Lindau as ovate, 

 12-15/x long; basidia olive green, 15-20/a thick (Krj^pt. Fl. Mark 

 Brand. 5a:920. 1914).

Plant forming small, convoluted, flattened pustules which touch 

 and crowd each other over considerable areas or in part may be only 

 gregarious. Individual pustules about 1-8 mm. broad and up to 4 mm. 

 high, wet but not viscid ; color pallid white to creamy yellow and 

 often with a distinct flesh tint so as to be more flesh color than yellow ; 

 texture firmly gelatinous.
