Spider Fungi: New species of Marasmius and Pusillomyces in the aerial rhizomorph web-maker guild in Amazonia.

ABSTRACT: Rhizomorphs are hair- or wire-like melanized structures with structural differentiation analogous to plant roots that help fungi spread over an area and find food resources. Some species of multiple groups of the Ascomycota and the Basidiomycota produce different types of rhizomorphs. In the Agaricales, the structures are largely found in Marasmiineae, particularly in the Omphalotaceae, Marasmiaceae, and Physalacriaceae. Many rhizomorph-forming species spread over the forest floor (ground level), while others form aerial litter-trapping rhizomorph systems that hang on living branches of the forest understorey. Here, we describe three new species that form aerial systems, two in Marasmius and one in Pusillomyces, all of which in
