Vinealobryum brachyphyllum resembles a miniature V. vineale in many ways, and indeed it has been considered a variety of that species in the past by some. The leaves are ovate-lanceolate like those of V. vineale, but they are much smaller. The leaves of V. brachyphyllum are usually well under a millimeter long. They are distally channeled like V. vineale and the margins are recurved. The reaction of the laminal cell walls in KOH is red. V. brachyphyllum was found in the Gila in a canyon with perennial water growing on rock near the creek. Vinealobryum brachyphyllum commonly has multicellular axillary gemmae. The
similar Husnotiella revoluta has unicellular axillary gemmae.
