| Determination | InQuestion Macromitrium homalacron Müller Halle |
| Determined by | Grout, Abel Joel |
| Annotation Text | Studied by A. J. Grout in the preparation of the Moss Flora of North America. I do not think this is M. longifolium. The leaves are highly mamulose and the peristome teeth are long and lanceolate. Not at all like those figored by Hooker's Muse. Exot. Pl. 44. Maybe M. homalichron |
