Discussion
Pylaisiadelpha tenuirostris is superficially similar to some specimens of Hypnum pallescens (Hypnaceae), a commonly sporophyte-bearing species with conic opercula and leaves lacking enlarged alar cells. Plants with sporophytes are rare. The rostrate opercula and conspicuous pigmented enlarged alar cells are distinctive.
Selected References
None.
