are also fewer in number, the undivided tips of the elaters, and the 

 absence, or rudimentary nature of the spinules on the spirals. 



Trichia intermedia, Mas=!. (n. sp.), fig. 1. 



Sporangia subglobose, sessile on a broad base, crowded, often 

 irregular from mutual pressure, smooth, shining, bright ochre ; mass 

 of capillitium and spores, clear pale chrome yellow ; threads simple, 

 cylindrical, about 10 //, thick, ending in a short smooth apiculus. 

 spirtils close, not prominent, sometimes branched, with a few short 

 spines here and there, connected by thinner raised hands running 

 parallel to the long axis of the thread ; spores globose, with distant 

 raised flat bands that rarely anastomose irregularly, surface of hands 

 with minute depressions, usually arranged in a single row, 9-11 /x 

 diameter. (Type in Herb. Kew.) 



On trunks, Scarborough ! 



The spores closely resemble those of Trichia JacMi, but the 

 spirals of the capillitium threads are connected by raised bands as in 

 Trichia chrysosperma, and the spines are rare and rudimentary. 

 Known from T. ajjinis by the bands on the spore not being uniformly 

 combined with a network, and the presence of ridges connecting the 

 spirals of the elaters. 



D. Spores with raised fiat hands combined to form a network. 



* Bands plain. 



Trichia chrysosperma, Eost., fig. 1 0. 



Sporangia crowded, rarely scattered, sessile on a broad or narrow 

 base, circular or irregular in form from mutual pressure, varying in 

 colour from clear pale yellow to ochraceous cinnamon ; mass of elaters 

 and spores yellow ; elaters cylindrical, 5-9 /j, thick, tips smooth, acute, 

 straight or slightly bent, not longer than diameter of elater, spirals 

 not very prominent, rather distant, sometimes with a few scattered 

 rudimentary spinules, connected hy thin ridges running parallel to 

 the long axis of the elater ; spores globose, with rather deep, narrow, 

 raised bands, combined into an irregular polygonal network, bands 

 not punctate, 12-15 fju diameter.

 n. 699, is Trichia varia in the Kew copy.
