    Description

    This chapter provides a brief synopsis of previous studies on the ecology of agaric decomposers that form litter 'mats' in tropical forests, augmented by data from temperate forest studies. Description of several experiments in tropical forests of the Luquillo Mountains in Puerto Rico is included. These studies showed higher rates of mass loss in leaves that were decomposed on basidiomycete mycelia (i.e., white-rot) than in the absence of basidiomycetes. The density of litter mats that were bound by basidiomycetes decreased with elevation and increased with slope. Addition of nitrogen inhibited mycelial growth. Capture of new litter by basidiomycetes was inhibited by nitrogen at high elevation. Litter-binding basidiomycetes exhibited differential responses to moisture, associated with full and partial shades. Micromphale bevipes was the only species that grew better in partial than in full shade. Marasmius crinis-equi had the highest rates of new attachments to litter in both full and partial shade, and was considered most suitable for use in restoration of steep road cuts and landslides to reduce erosion.
