This work I do under an old stereo microscope (Wild from Switzerland) with 10-40x magnification. For the tweezers I use the Nr. 5 from DUMONT, also Switzerland. For the tiny leaves just strip of some and choose the best.
Pelekium (Cyrto-hypnum) schistocalyx (C. M.) Buck & Crum
Venezuela, W-Llanos, Forestal Reserve Caparo, semi-humid rainforest, epiphytic on tree trunk, 140 m, leg Lüth 3321, 2001
Very small size, pluripapillose leaf cells and ciliate perichaetial leaves.

characteristic are the small brood branchlets (Bt) in leaf axis
Thanks for the question. I made a picture plate of a moss from my old moss collection from the Neotropic 2001.
Btw your blanket/carpet will get very beautiful.
Beautiful picture. The moss with the sporophytes is Ptychostomum capillare, the creeping one Hypnum cupressiforme. Unfortunately no Bonfire.
Breutelia tomentosa (Sw. ex Brid) Jaeg)
Venezuela, Andes, Merida, way to Laguna Coromoto, upper cloud forest, on wet soil over rock, gneis, 2500 m, leg. Lüth 3319, 2001
Remind in microscopical characters to B. subarcuata, but differs in only 2-3 inflated alar cells.
Caribaeohypnum polypterum (Mitt.) Ando & Hig.

Pilotrichella flexilis (Hedw.) Angstr.
Venezuela, Andes, Merida, surrounding Laguna Coromoto, upper cloud forest, pendent from branches of trees, 2500 m, leg M. Lüth 3314
I make the photos, this is a electronic kind of "permanent slide", because I always can look at them easily.
Rhodobryum huillense (Welw. & Duby) Touw
Venezuela, Andes, Merida, surrounding Laguna Coromoto, Upper cloud forest, on rotten stump, 2550 m, leg M. Lüth 3313
Looks a bit like R. grandifolium, but plants and leaves are much smaller.
I do not know exactly, what you want to know. I just use water to work with the microscope. But what is mounting medium?
Rhodobryum grandifolium (Tayl.) C. Müll.
Venezuela, Andes, Merida, surrounding Laguna Coromoto, Subparamos, on open humose rock, gneis, 3000 m, leg M. Lüth 3305
Very nice landscape with a lot of bryophytes. I think L. cupressina is quite common in that region. Perhaps it is overgrown here from one of the big pleurocarp moss. But it will come at another place again.
Beim Hineinfassen aber bitte nicht zerstören. Das Polster ist vermutlich Jahrzehnte alt.
Du wirst sie schon begeistern! Da hab ich keine Bedenken...
Grimmia austrofunalis Müll. Hal.
Andes, Merida, sourrounding of Laguna Coromoto, Subparamos, on open rock, gneis, 3000 m, leg 2001 M. Lüth 3302
Stem without central strand, costal cells mostly uniform, hydroids lacking, big and somewhat glossy plants
Bartramia microstoma Mitt.
Andes, Merida, on way to Laguna Coromoto, open part in cloud forest, on steep slope, at 2700 m, leg 2001 Lüth 3300
Reminds to a small B. itiphyllum, but with different shape of leaf base and has firm though pellucid cells at shoulder margins.
Atractylocarpus longisetus (Hooker) Bartram
Andes, Merida, on way to Laguna Coromoto, cloud forest, on root of tree, at 2500 m, leg 2001 Lüth 3297
Unlike to Campylopus with costa smooth at back.
Porotrichum lancifrons (Hampe) Mitt.
Venezuela, Andes, Merida, way to Laguna Coromoto, cloud forest, on tree trunk and root, 2500 m, leg. 2001 Lüth 3295.
Characterized by well-developed stipe and strongly appressed hyalin stipe leaves.

Venezuela, Andes, Merida, Pico Bolivar, way to Bosque de Coloradito, on rocky soil, 4100 m, leg. 2001 Lüth 3262, det. J.-P. Frahm
Lobaria amplissima is extremly rare in Germany. 2020 one of the old trees died and the bark with Lobaria fall on the ground. So I took it and fixed it with binding wire on another old tree near by (without the Lobaria). Yesterday I was there and pleasantly surprised, that it worked very good.
