  {We report the discovery of 20 new dwarf galaxies in the Local Volume
identified as optical counterparts to the Five-hundred-meter Aperture Spherical
radio Telescope (FAST) All Sky HI Survey (FASHI) sources. The galaxies have a
median stellar mass of $7.8\times 10^6~M_{\odot}$ and a median HI mass of
$1.0\times 10^7~M_{\odot}$. Most of them are field galaxies, while three are
probable members of the M 101 and M 106 groups. We also found seven FASHI radio
sources to be probable dark HI clouds in nearby groups. Together with four
other known HI clouds in the local groups, their mean-square radial velocity
difference of 49~km~s$^{-1}$ with respect to the host galaxies yields an
average total mass of ($2.7\pm1.0)\times10^{11}~M_{\odot}$ for these groups on
the projected scale of 90 kpc.
