Brief Description:

Literature :
Ryvarden, L. 2004. Neotropical Polypores. Part 1. Introduction, Hymenochaetaceae and Ganodermataceae. Synopsis Fungorum. 19:1-227

Page number : 99
Remarks (internal) : The species is above all recognized by the dark resinous bands in the pale brown context, reminiscent of the core seen in Amauroderma. As usual in Ganoderma, its basidiocarps can vary considerably from sessile to laterally stipitate. The cuticle is difficult to crush and is rather thick especially on the stipe.
