Only four star clusters are known within ~100 pc of Earth. Of these, the Chi1For cluster has barely been studied. We use the Gaia DR2 catalog and otherpublished data to establish the cluster membership, structure, and age. The ageof and distance to the cluster are ~40 Myr and 104 pc, respectively. Aremarkable, unprecedented, aspect of the cluster is the large percentage ofM-type stars with warm excess infrared emission due to orbiting dust grains --these stars lie in an annulus that straddles the tidal radius of the cluster.The Chi1 For cluster appears to be closely related to two extensive, previouslyknown, groups of co-moving, coeval stars (the Tucana-Horologium and ColumbaAssociations) that are spread over much of the southern sky. While Tuc-Hor andChi1 For are comoving and coeval, the difference in the frequency of their warmdusty debris disks at M-type stars could hardly be more dramatic.
