Variable in size, from that of a hazel-nut to a walnut. 
Peridium at first white, slightly tinged with lemon-colour ; 
cells at first white, gradually becoming of a dull buff, and then 
of a reddish grey or brown. Smell like that of Lactarius 
theiogalus . Spores ovate, shortly pedicellate, with an abrupt, 
elongated, sometimes irregular apex, in general smooth and 
transparent, and containing 2-3 nuclei, but sometimes slightly 
rugose, though by no means opaque, as in H. citrinus , from 
which it may be known by its reddish substance, larger cells, 
more transparent, paler, and smoother spores, which are fre- 
quently more abruptly acuminate. (M. J. B., 1 . c.)

Spores narrowly fusiform, smooth, pale amber, 25-26 x 8-iOju,.

An Hymenogaster occurred at Hartham Park in the autumn 
of 1845, nearly intermediate between H. citrinus and H oli- 
vaceus , differing from the former in being of a pale watery 
brown within, and of a softer texture, with the spores exactly 
intermediate between those of the two species. The scent was 
something like that of H. citrinus , but not so strong. It was 
not at all yellow externally, but first white, and then of a 
watery brown. It grew in a very dry fir-plantation, therefore 
its watery texture could not arise from situation, especially 
since H. citrinus occurs in much moister situations without any 
similar appearance. We consider it best for the present to 
record it as a variety of H. olivaceus , differing in scent and in 
form of the spores. (M. J. B., 1 . c.) 
Hymenogaster tener, Berk. (Figs. 1 and 54 )- Small, glo- 
bose, soft, white, silky, substance pale pink, then greyish 
umber ; sterile base conspicuous, white ; spores broadly ellip- 
tic, with a papillary apex, verruculose or rugulose, ochraceous,
