In по. 347. 4 the pores are rather larger than іп no. 336, which seems to be the only 
difference.

it comes near to H. tenuis and H. variegata. Brisbane CF. M. Bailey, no. 342).

“ This species is almost orange-coloured when fresh; it contracts much in drying. 
The hymenium seems sometimes like that of a Dedalea.”—F. M. B. It seems to 
partake of the characters of both the genera; but its texture and general habit resemble 
rather those of Merulius. The upper surface of the pileus is lacerate, especially at the 
margin, where it is strongly incurved when dry; the hymenium is reticulate in some 
places, in others it exhibits folds; ina small specimen laterally confluent with the larger 
one, the folds assume the appearance of gills; the colour when dry is a dark rusty brown, 
the original orange tint is perceptible here and there on the upper surface. The larger 
specimen is about 2 inches wide by 14 long, the lesser ones about 2 of an inch. Brisbane

Parasitic apparently on some Hymenochete, on whose hymenium it forms very thin 
irregular closely adherent patches of a yellowish-brown colour, which exhibit extremely 
delicate reticulations towards their centre, measuring about + of a line across the inner 
substance shown where the hymenium is cracked, and at the margin is nearly white.
