Three scenarios for miniature loop-like structures seen between 1 MK and 2 MK. A) Small loops spanning across one granule, B) short elongated structures at the footpoint of a hot loop, e.g. moss, and C) footpoint segments of a dilute hot loop heated from below (see Sect. 1). The black solid lines indicate granules. The blue and red colours in the loop features denote warm (1 MK to 2 MK) and hot (>5 MK) plasma. The arrows represent the direction of the energy flux powering the bright feature, that is, in panel B) the heat flux from the corona down to the lower atmosphere and in panel C) the Poynting flux into the upper atmosphere.
