Distrib Common in tropics. 
Hennings (Engl. Bot. Jahrb. xiv. 362 (1892)) has proposed the generic 
name Pilocratera to replace the name T'richoscypha (Cooke) Sace. (1. ¢.)— 
the latter name having been used by Cooke (187%) 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 nomina 
conservanda 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 Ramsbottom, sp. nov. 
Rubra ; ascomatibus ceraceo-carnosis, stipitato-cupulatis, 1-5-2 cm. diam., extus 
pruinosis, margine pilosis, quoque pilo e tubulis septatis hyalinis coalitis composito, 
cupulo hemispherico, stipite compresso, 3-3°5 cm. longo, 1 mm. crasso, pruinoso ; 
ascis cylindraceis, c. 320 » x 15-16 p, breviter stipitatis, partibus sporiferis c. 170 p 
longis, apice non iodo cerulescentibus, octosporis; sporis monostichis, fusoideo- 
ellipticis, biguttulatis, 23-28 » x 12-15 »; paraphysibus cylindraceis, septatis, 5 pu 
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 » in length, with a base of about 150 yw. The cells of the peridium 
are spherical, and vary in size from about 25 « towards the middle of the 
disc to about 10 » at the margin. They are thick-walled, as are also the 
paraphyses and spores.
