Re: Moss species for James
Paul K. mentioned mosses of the Genus Mnium as being potential candidates
for use in an aquarium. Thanks Paul.
I accessed the online key from the Bryophyte Flora of North America at
http://www.nybg.org/bsci/bfna/keytable.html, and looked for listings for
Fontinalis, Vesicularia and Mnium. Here is what it says.....
48. Plants aquatic, occurring submerged at least part of the year; leaves
keeled or flat. Fontinalis
62. Lateral and dorsal leaves differentiated in areolation; stems pinnately
303. No leaves with lamellae; costa with or without a single stereid band;
exostome of 16 free teeth. Mnium
Looks like you really DO need to be an expert to figure these things out....
In an effort to see if I could find out more about this Mnium moss, I
checked both the USDA Plant Database and the ITIS Database. I wanted to see
where, in relation to both Fontinalis and Vesicularia, bryologists place the
moss in the greater scheme of things and to check on the validity of the
name and the various species. I couldn't locate any listing in either of
these sources for the species name given by Paul - Mnium punctatum. I did
find others though (listed below).

While these 2 sources had nothing to say about M. punctatum, it is mentioned
and keyed out in "Moss of New England" at
http://members.aol.com/legion86/MOSS71.html and also at
http://members.aol.com/legion86/MOSS33.html. This source makes definate
mention of the wet habitat preferred by the Genus in general. Possibly very
good possibilities for use in an aquarium.
Through Google, I found a link to a page that calls Mnium "Carpet Moss" and
describes its use as a groundcover in gardens (Mnium hornum -
http://www.blueplanetbiomes.org/carpet_moss.htm). There are some nice images
online at Bioimages.Org in the UK - closeup of the plant:
Also through Google, I found a personal website done by a guy here in
Ontario "Leatherwood Trail - A Graphic Guide to Ontario Mosses"
[http://wmuma.com/moss/ggom.html]. He lists a number of Genera from wet
habitats which I suppose might be possibilities:
