trem1.jpg (6046 bytes) Phragmobasidiomycetes - Tremellales -  stained, cruciately septate basidia.  Nuclei are dark. 
Note the long epibasidia..

X 2/3
trem5.jpg (4855 bytes) Phragmobasidiomycetes - Tremellales - basidioma of Pseudohydnum.  The 'teeth' make this look hydnaceous, but the jelly-like consistency and the cruciately septate basidia soon put you on the right track.
