578 NoTOTHYLAS. 
1, NoTOTHYLAS AMAZONICA, Spruce. 
Hab. in solo limoso sylvarum prope Tarapoto, ad Andium radices, necnon 
in fluvii Ramos, flum. Amazonum tributarii, ripis. 
Frondis radius 15:0™™; cellule 35; invol 3:0; capsula 3°5x°7; spore 
Frondes orbiculares subplane virescentes, radicellis brevibus matrici 
arcte adnate, profunde lobatie, lobis subimbricatis crenatis, medio 
sparse setulosis, tenues, intus hic illic gonidia viridia monstrantes ; 
cellule bistratee majuscule subconformes. 
Involuecra loborum axi insidentia, alia basi alia apici proxima, corni- 
formia, basi paulo latiora, depressa fere horizontalia, apice scarioso 
clausa demum rupta. Capsula basi bulbosa fere sessilis, cylindrico- 
fusiformis, decurvula, flavida, bivalvis, valvulis margine indistincte 
coloratis, inferne cellulis elongatis 3-5-stratis conflata. Columelle 
nulla vestigia invenire potui. Spore magne fusco-luteze angulato- 
rotund. Elaterum frustula pallida subquadrata amorphave. 
Obs. Planta ad fl. Ramos lecta duplo minor est, parce fructifera, capsulis 
autem sporisque typo conformibus. In utraque forma columellam frustra 
quesivi. Columelle absentia e capsulis supramaturis probabiliter evenit, 
ejus residua forsan cum elaterum frustulis mixta et confusa e capsula 
rupta simul ejecta. 
N. valvata Sulliv. in ‘Musci Allech.’ no. 289, a nostra egre distincta, 
differt statura minore ; capsulis infra medium paulo latioribus, ovato- 
cylindricis, superne late obtuse subulatis ; columella lata utrinque appen- 
diculata; sporis pallidis. NN. melanospora ejusd., quoad columellam vix 
diversa, specifice differre haud videtur.
