MR. GEORGE MASSEE ON THE THELEPHORER. 187 
CONIOPHORA OCHRACEA, Massee, n. sp. Latissime effusa, sub- 
membranacea, indeterminata; hymenio pulverulento, ochraceo ; 
spore flavide, subglobose, 8 x 6-7 u. (Pl. XLVII. f.13.) (Type 
in Herb. Kew.) 
Spreading continuously over the inside of elm-bark which had 
become slightly separated from the wood of a prostrate trunk. 
England (Kew). 
In its most perfect state resembling a thin form of C. sulphurea, 
from which it is distinct in the size and form of the spores and 
absence of a determinate fibrillose margin. The subhymenial 
hyphe are very thick and coloured, measuring up to 18 p diam., 
from which the erect branches bearing the clustered basidia often 
arise in opposite pairs. This species is very instructive, as in 
many instances stout prostrate hyphe grow beyond the compact 
mass and produce isolated tufts of erect basidia-bearing branches, 
which can be readily removed for examination ; in this particular 
it agrees with Corticium arachnoideum, Berk.
