Of the 52 collections examined, 21 had echinate macroomamentation; 19, aculeate; 6, cristate; 5, psilate; and 1, laevigate (Appendix I).
Of the three macroornamentation types, the designation "cristate" proved most problematical in this study because it is difficult to distinguish between very broad bullae and narrow cristae.
Corner (1957) stated: "Both Singer's collections have spores up to 17 X 5 [micro]m, and the branch-tips tended to be cristate
, which is unusual." The latter character, basidiome color, and spore shape are the three leading separating characters for L.
Lateral carinae of pronotum absent, medial carina of the pronotum nodular and to some degree cristate
, with a prominent projection in the prozona and one or two lower ones at the rear of the metazona.
