Distrib Common in tropics. 



Hennings (Engl. Bot. Jahrb. xiv. 363 (1892)) lias proposed the generic 

 name Pilocratera to replace the name Trichos<-ypha (Cooko) Sacc. (/. c.) 

 the latter name having been used by Cooke (1879) as a subgenus. As 

 in several cases, the name has been duplicated in different plant-groups, 

 J. D. Hooker (Benth. & Hook. Gen. Plant, i. 423 (1862)) using it for a 

 genus of Anacardiacese. The question of these duplicate names should be 

 considered in general ; it can then be seen whether the principle of nomiiia 

 consercanda should be invoked for the name in one group used for a large 

 number of species in a well-known genus, as against the name used for 

 a little-known genus with few species. 



PILOCRATERA NOVO GUINEENSIS R:imsbottom, sp. nov. 



Rubra ; ascomatibus ceraceo-carnosis, stipitato-cupulatis, 1*5-2 cm. diam., extus 

 pruinosis, margine pilosis, quoque pilo e tubulis septatis hyalinis coalitis composite, 

 cupulo hemispherico, stipite compresso, 3-3'5 cm. longo, 1 nim. crasso, pruinoso ; 

 ascis cylindraceis, c. 320 yu. x 15-16 yu, breviter stipitatis, partibus sporiferis c. 170 fi 

 longis, apice non iodo caerulescentibus, octosporis ; sporis monostichis, fusoideo- 

 ellipticis, biguttulatis, 23-28 p. x 12-15 p. ; paraphysibus cylindraceis, septatis, 5 p. 

 crassis. 



In ligno putrido. 



The hairs on the disc margin are composed of a cone of septate hyaline 

 filaments, which are about 7-8 //. wide at the base. The cone is about 

 350 p in length, with a base of about 150 /A. The cells of the peridium 

 are spherical, and vary in size from about 25 fj, towards the middle of the 

 disc to about 10 ft at the margin. They are thick-walled, as are also the 

 paraphyses and spores.
