tenellum, auratum, late gregarium v. cespitosum, parce dichotomum, 
erectum, subrosulatum. Folia caulina laxe appressa, e basi breviter 
spathulata oblongo-ovata, cuspide acuminata, undulate flexuosa, pulcher- 
rime aurato-flavida, ubique crassiuscule flavide limbata integerrima, 
nervo parum carinato flexuoso ante apicem evanido, cellulis ubique fere 
parvis pachydermibus flavidis subrotundis, basis infimze fuscis laxis, basis

aperta urceolata, subrugulosa, intense fusca, operculo conico subulato 
recto, calyptra eleganter aurate fimbriata glabra; peristomium minutis-

9. D. Dicksowi (Hook. Lond. Journ. ii. 549, Hookeria) Rami 
intricate ezespitosi. Folia compressa, lateralia patentia divergentia, omnia 
zqualia obovata, apice apiculo brevi angusto, nervis ultra medium eva- 
nidis, marginibus limbo angusto, cellulis superioribus rotundatis diametro
