The presence of this widespread species in the Philippines was not unexpected. It grows abundantly on disturbed clayey banks. Among the Philippine Dicranella taxa, D. leibergii Williams comes closest to it. The two taxa share characters, such as the elongate upper leaf cells and the subcylindric, erect capsules. Nevertheless, the former has flat or slightly recurved leaf margins (Williams, 1915) while Microdus miquelianus has thickened leaf margins. The Philippine plants the produce highly variable capsules ranging short-oblong to cylindric. The color ofthe setae likewise exhibit a range of colors from yellow to red. The illustration named Microdus insularis (Williams) Broth, in Del Rosario (1979, p. 25) should be corrected to Microdus miquelianus. Microdus insularis has long and narrow or suhulate-acuminate leaves with long upper leaf cells (15 to 25 times as long). Both features are clearly illustrated in Bartram (1939).
