ENUMERATION OF FUNGI. 415 
roundish, or by the absorption of the dissepiments, elongated, 
fawn-coloured ; dissepiments thin, with their margin-nearly 
even, Little granular bodies are often attached to them, 
but they are possibly extraneous. 
Var. imbricata ; imbricata, pileo tenui coriaceo flexili velu- 
tino-villoso vel spongioso rarius fasciculato-piloso. Zeyher, 
n. 118, 120. 
On decayed wood, in the forests near Uitenhage and Zwart 
Kops River. March. 
At first sight, very different from the more normal form, 
but varying as greatly in the nature of the pubescence, which 
is villous or spongy, or fasciculato-pilose. The pilei scarcely 
exceed an inch in breadth. The substance is of the same 
colour but is rather softer, though it varies also in this 
respect. 
No species can be more variable than this. It would be 
easy to make several species, but whatever difference there 
may be in the surface of the pileus, the form, thickness, and 
density, there is none in the pores or the colour of the sub- 
stance. The two forms described as a variety are most dif- 
ferent; but these are so connected with the others, that it 
seems impossible to make more than one species. The dif- 
ferences arise probably from the situation in which they 
were developed. Its nearest ally appears to be my Pol. Zey- 
lanicus. 
17. Pol. (Apus) isidioides, n. s.; pileo suberoso-lignoso 
uniformi convexo duro gilvo-ferrugineo margine subtiliter 
velutino ruguloso, postice setoso-scaberrimo ; intus rhabar- 
barino; hymenio plano cinnamomeo; poris minutissimis 
punctiformibus. Zeyher, n. 115. 
Upon trees, in forests near Uitenhage. March. 
Pileus 3 inches broad, 2 long, reniform, convex above, 
plane below, stemless, of a rich ferruginous reddish grey, 
hard and woody, very obscurely zoned, minutely rugulose, 
and velvety towards the margin, with occasionally smooth, 
brown, shining, darker zones behind, remarkably scabrous, 
with elongated bristly nodules; substance hard, rhubarb-
