Family:Dicranaceae
Description:Species Description - Plants very robust and tall, to 12 cm high, yellowish to brownish green. Stems with reddish tomentum. Leaves 8-12 mm long, canaliculate, narrowly lanceolate, ending in a long, serrate subula. Costa filling 1/3 of the leaf base, in transverse section with multilayered bands of ventral and dorsal stereids, excurrent. Alar cells large, reddish, inflated and prominent. Basal laminal cells rectangular, 20-25 × 50-100 µm, incrassate and pitted, narrower at margins. Upper laminal cells incrassate, strongly pitted, narrowly lanceolate to elongate, 2-5 × 13-25 µm. Sporophyte not known.

Discussion:In the strongly pitted basal laminal cells and the inflated reddish alar cells this species strongly resembles Dicranodontium subporodictyon Brotherus, a holarctic species, occurring in China, western North America and western Europe. The relationship between these species is not clear and needs further study.
