SUMMARY OF CURRENT RESEARCHES RELATING TO 
regular dehiscence is effected, alone separates Nanomitrium from Epheme- 
tmm , ; the author placing both genera in the Funariaceae. 
Fructification of Ephemsropsis tjibodensis.* — Herr M. Fleischer 
has met with the hitherto unknown capsule of this rare Javanese moss, 
which determines it to belong to the series of the Hookeriacese, rather 
than of the Ephemeraceee. It is usually dioecious. The very remark- 
able persistent protoneme forms a dense felt on Phanerogams and ferns, 
to which it is fixed by peculiar organs of attachment. This structure 
branches copiously in a dichotomous manner into dorsiventral filaments, 
and produces gemmae. 
New Genera of Mosses. — Among Giraldi’s collection of mosses from 
■< ’hina, the late C. Muller f describes no less than 112 new species, and 
the following new genus belonging to the Entodontaceae. 
Giraldiella g. n. Cespites robusti, brachytheciacei ; caulis decum- 
bens, ramis brevibus turgesceutibus lepyrodontoideis divisus ; folia 
robusta entodontoidea, binervia, cellulis alaribus multis parenchymatibus 
ornata ; theca entodontoidea, robusta ; calyptra dimidiata, albula ; peri- 
•stomium duplex, robustum, Ion gum ; dentes externi anguste lanceolato- 
subulati, articulati, cristati, hypnoidei ; interni in membrana reticulata 
longi in lacinias angustissimas impellucidas binas v. parum flexuosas 
carnosas fissi. 
From S. Africa the same author J describes a new genus of Syrrho- 
podontacese, Hypodontium, with the following diagnosis : — Plantse altse, 
robustse, cespites densos v. compactos sed laxe coherentes sistentes, 
parce dichotomy divisse, folia dense imbricata, plus minusve circinato- 
crispatula et involutacea, basi vaginacea, crassinervia, firma ; peristo- 
mium simplex externum; dentes 16, lati-lanceolati, integri, v. apice 
fissiles, interdum furcati, tirmi, suberrimi, robu^te articulati, glabri, 
profunde infra orificium thecae firmae ellipticse v. pomiformis oriundi ; 
•calyptra dimidiata, inflorescentia dioica. 
From Japan M. E. Bescherelle § describes the following new genus 
of pleurocarpous mosses. 
Pilotrichopsis g. n. Rami penduli, semipedalcs et ultra, graciles, laxe 
•et remote pinnati, ramulis apice attenuate stoloniformibus patentibus 
plerumque simplicibus divisi ; folia appressa, ovato-lanceolata, subplicata, 
unicostata, basi exauriculata, cellulis ovalibus inferioribus ad margines 
oblique quadratis ; perichaetia ad ramos et ramulos producta. 
New Fossil Moss.|] — Under the name Bhynchostegium Knowltoni , 
Mrs. Elizabeth G. Britton describes a fossil moss from the Lower Mio- 
cene or Upper Eocene strata in Washington Territory, U.S.A. 
Tubers in the Hepaticae.^T — Mr. M. A. Howe describes the occur- 
rence of “ tubers” in 11 species of Hepatic**?, viz. 4 of Anthoceros, 3 of 
Biccia , 2 of Petalophyllurn , 1 of F^ssombronia, and 1 of Geotliallus. In 
Anthoceros phymatodes , from California, the “ tuber ” first appears as a 
swelling near the apparent apex of a costa-like thickening of a tliallus
