Clastoderma debaryanum is recognized by its small size, until 1,2mm total height, stalk brownish filled with granular material bellow, translucent and tapering abruptly upwards after a droplet-like swelling; filament of the capillitium with membranous platelets attached at the tip (Barbosa, et al., 2016).

Although to be a well distributed species, in Brazil this species need attention because many records are from endangered biomes. Thus, I suggest this species to be categorized in Least Concern

The species is known in 51 countries. In Brazil it is known in 8 of 26 states (AL, BA, PB, PE, PI, RN, SP and SC).

There are about 1030 records among 51 countries, 70 of records are from Brazil.

In Brazil the species is found on dead leaves, decomposing trunk and living tree bark in disturbed and preserved areas, caatinga, savanna, mangrove and riparian forest and atlantic forest.

The species is well distributed in Brazil, mostly in northeast region, it is present in Biomes which have been losing its biological diversity due to deforestation, agricultural activities and urbanization.

Some records are from unprotected areas or threatened Biomes.

More researches in Brazil are necessary, mostly in north and midwest region which has no record. Are necessary field collection and moist chamber techniques using various types of substrate.

None.
