Tropica, AFrica. Nairobi, on dead wood, Dr. Van Sumerun, 
Oot. 1920. 
A beautiful species, of a uniform dull brown colour (‘“ Mummy 
Brown” of Ridgway), with large fairly regular pores. It 
evidently belongs to the same section as H. subvelutina Wakef., 
but differs from that species in its regular shape, and especially 
in colour. The silky appearance of the pileus is a marked 
character. Bearing in mind the very different appearances which 
H. Pobeguini may assume at different stages, it seems just possible 
that both this plant and H. subvelutina may be forms of one 
species. The three fine specimens in the present collection 
are however all alike and show no suggestion of transition.

Inpia. Ganjam, Madras, encrusting the bases of young 
saplings of Shorea robusta, Gaertn. f., A. F. Minchin, Aug. 1918. 
This species is very close to 8. incrustans, Tul., which it 
resembles in habit, texture, and colour when dry. The specimen 
sent is almost entirely resupinate, but there is evidence of a 
tendency to form small columnar or fan-shaped outgrowths such 
as occur in 8. incrustans. The present plant differs chiefly in 
the smaller size of hyphae, basidia, and spores. In structure it 
shows three very distinct layers, hymenium, a medial layer of 
loosely woven hyphae, and a basal layer of close parallel hyphae 
next the substratum.
