362 HTPOG^I. 



The yellow veins, subfusiform, rough, dark-coloured spores, the frequently 

 coloured sporophores, and the cheese-like scent which communicates itself 

 to everything which is near, are the criterions of this species. When young 

 it is of a greenish -yellow, but this soon wears oflFwhen rubbed, or exposed 

 to the air. The sporophores occasionally become of a much darker colour 

 than the neighbouring cells, and have a resinous appearance.— ^.dt. Br. 



1060. Hymenogasteir olivaceus. Vitt. " Olive Hymenogaster." 



Globose, but angular; peridium -whitisli, tlaen tinged with 

 yellow, rufous when bruised ; substance white, then of a dull 

 buff, then rufous-olive, variegated with the white trama ; spores 

 pedicellate, mucronate, generally smooth. — B. ^' Br. Ann. N.H.

In woods. West of England. 



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 be- 

 c^ming of a dull bufiF, and then of a reddish grey or brown. Smell like 

 thaX of Lactarim theio^atas. Spores ovate, shortly pedicellate, with an ab- 

 rupt, elongated, sometimes irregular apex; in general smooth and trans- 

 parent, and containing 2-3 nuclei, but sometimes slightly rugose, though by 

 no means opaque, as in H. citrimis, from which it ir.ay be known by its red- 

 dish substance, larger cells, more transparent, paler and smoother spores, 

 which are frequently more abruptly acuminate. — 21. J. B. 



1061. Hymenogaster tenei. Berk. " Thin Hymenogaster." 



Small, globose, soft, white, silky ; substance pale pink, then 

 greyish-umber ; sterile base consjDicuous, white ; sjDores broadly 

 elliptic, with a papillary apex, minutely warty. — Berk. Ann. N.H.

In woods. Spring and summer. West of England. 



About the size of a bean or large hazel-nut ; globose, soft and tender, 

 wliite and silky externally ; peridium thin, at length dingy, at first white 

 within, but soon acquiring a delicate pink tinge, which, as the spores ripen, 

 changes to an umber grey. Absorbing base white, very distinct ; cells looser 

 than in II. olivaceus ; spores much smaller than in the neighbouring species, 

 broad, elliptic, with a minute papilla, never acuminate, minutely verrucose. 

 Smell like that of Lact.theioyalas. — M.J.B. This is one of the most distinct 

 species, characterised by its small, widely elliptic, or subglobose spores. 

 Spores -016- -019 mm. long, •0096--0105 mm. broad (•0005--U(.U6 X -00035- 

 ■0004 in.). (Fig. 107, fun>jus and section.) 



1062. Hymenogaster Th-waitesii. B.<^'Br. " Thwaites's 



Hymenogaster." 



Small, globose, firm, dirty white, here and there stained ; sub- 

 stance brown ; spores globose, rather rough, papillary. — B. 4'Br.
