Species description:
Genus name refers to the relationship to Dicranum and the re­semblance to another moss, Weissia. Species name referring to the sharp pointed leaves.

Comments:
This moss must be highly tolerant to exhaust fumes be­cause it often abounds on trees along busy urban streets.

Distinguishing characteristics:
The usual epiphytic habitat and turf-­forming masses added to the erect sporophytes with red peristomes, are distinctive.

Habit:
Forming turfs or tufts of dark green to light green plants.

Similar Species:
Zygodon viridissimus is less common in the same habi­tat and also produces abundant gemmae. The tufts are not as condensed and the leaves coil helically around the shoot when dry; in Dicranoweisia the leaves are individually twisted in all directions. Orthotrichum con­simile, occurring often on the same trees as Dicranoweisia, has short setae and grooved sporangia; peristome teeth in Orthotrichum are in two rows rather than one, as in Dicranoweisia.
