concava; ramulina minora brevius aristata; theca in pedunculo 
tenui pallide rubente pro plantula longiusculo pollicari apice 
eygneolo nutans, e collo tenui anguste oblonga ochracea. dein- 
que fuscata parva, operculo minuto conico breviter acutiusculo, 
annulo lato revolubili; peristomium parvum: dentes cexterni 
breves dense trabeculali, interni teneri breviores sulcati ad 
suleum planiusculum brevem hiantes breviter cuspidati, ciliolis

Ex habitu formis minoribus Bryi cespiticii haud dissimile, 
sed peristomio Pohliae, constructione folii longipili lato limbati, 
forma thecae angustata brevicollo atque inflorescentia synoica 
longe diversum et tenella species. Forma fructibus magis ob- 
longis foliisque minoribus angustius limbatis leg. Dr. Krause 
in valle Dejae 4. Majo 1882. Specimina Chilcooliana formam 
robustiorem fructibus distinete anguste pyriformi-oblongis brevi- 
collibus repraesentant. Species varisbilis videlur, sed inflore- 
scentia synoics foliis longe aristatis usque ad acumen revolutis 
inde planis plus minus flavide limbatis et peristomio facile 
distinguenda.
