A Bevision of the Trichiacese. By G. Massee, 345 



Trichia superha, Mass. (n. sp.), fig. 6. 



Botryoid, rarely simple. Sporangia broadly dbovate, pale yellow, 

 common stem more or less wrinkled longitudinally, often twisted, 

 colour of the sporangium above becoming orange downwards, springing 

 from a well-developed hypothallus ; mass of capillitium and spores 

 deep yellow; elaters simple, cylindrical, 9-11 /i thick, with abruptly 

 tapering, smooth, short ends, often more or less bent, spirals close, 

 thin, but little prominent ; spores globose, with raised fiat hands com- 

 hined into a polygonal network ; hands with a row of minute depres- 

 sions, 17-20 fji diameter. 



(Type in Herb. Kew.) 



On mosses and logs. New Zealand ! 



Allied to Trichia afflnis, but known by the much larger spores 

 with smaller and more numerous reticulations, and the obovate 

 sporangia arranged in a botryoid manner, and supported on a long 

 stem. 



Plants scattered, 3-4 mm. high, stem about equal in length to the 

 sporangium, thin and weak, so that the sporangia are often drooping. 

 From three to four polygons present on a hemisphere of the spore. 



Trichia Kiclcxii, Eost. 



Sporangia spherical, sessile, in several crowded strata forming 

 cakes some mm. high, and sometimes several cm. long and hroad ; 

 walls of single sporangia rigid, flesh-colour, polished and shining ; 

 elaters simple, either flexuous or curved into circles, 4'2 /x thick, 

 spirals two, not very prominent; tips obtuse; spores with an irre- 

 gular network, 14-15 fj. diameter.

Trichia pusilla, Schroeter. 



Sporangia subglobose, very small, 0*3-0 '5 mm. diameter, gre- 

 garious, scattered or collected in clusters, golden or brownish-yellow, 

 smooth, shining, fragile ; hypothallus absent ; elaters very short, about 

 100 /i long, 4-5 /a thick, here and there thickened, apices rounded, 

 often mucronate and curved, 4-5 /x long ; spirals 2-3, slightly pro- 

 minent, here and there inconspicuous ; spores globose, unequally 

 costulato-reticulate, 11-12 ^u, diameter.

On bark. Germany. 



Oligonema, Eost. 



Wall of sporangium single, dehiscing irregularly; capillitium 

 composed of free, simple, or branched elaters, furnished with ring-like 

 thickenings, or rudimentary spirals, tips obtuse ; spores globose.
