Key to the Species of Funariaceae in Brazil

1. Capsule asymmetric, inclined to subpendent; peristome double, endostome well developed...........................................................2

1. Capsule erect and symmetric; peristome simple or reduced, endostome rudimentary or absent ..................................................... 3

2. Capsule strongly inclined, neck smooth; when dry the mouth is smaller than the width of the capsule; peristome teeth smooth, trabeculae sigmoid........................................................................................................................................... Funaria hygrometrica

2. Capsule pendulous, nearly horizontal, neck striated; when dry the mouth is wider than the width of the capsule; peristome teeth papillose, trabeculae straight ...............................................................................................................................

3. Capsule pyriform or domed, when dry the mouth is wider than width of the capsule; exothecial cells isodiametric, near 1:1; peristome absent; calyptra mitrate, base with valves ....................................................................................................................... 4

3. Capsule cylindrical, when dry the mouth is smaller than width of the capsule; exothecial cells longitudinally elongate, near 2–3:1; peristome simple, sometimes rudimentary; calyptra cuculatel, smooth with inflated base, valves none ........................................ 8
