462 BRITISH FUNCil 



the trama white (spores l)r()ad]y fusiform, with a sharp point at 

 each end, pedicellate, brown, generall}' quite smooth, 25-jox 



Peridium variable in size, at first white with a tinge of lemon- 

 colour, gradually changing to a dull buff-colour, and finally to 

 reddish grey or brown. Smell like that of Ladarius theiogalns. 



Underground in woods. A common species in the West of 

 England. 



var. niodestus. — Spores narrowly fusiform, smooth, pale amber, 

 25-26 X 8-g II. 



This form is intermediate between H. citriniis and H. olivaceus, 

 differing from the former in being of a pale watery brown colour 

 inside, and of a softer texture, and having the spores exactly inter- 

 mediate between those of the two species. The smell resembles 

 that of H. citrinus, but is not so strong. 



Underground in dry fir woods. 



H. tener. — Peridium small, subglobose, soft, white and silky, 

 i-| in. across ; inside pale pink, then becoming greyish umber 

 as the spores ripen ; sterile base well marked, white (spores broadly 

 elliptical, with a papilla at the apex, minutely warted or wrinkled, 

 ochraceous, 30x14-16 /x). 



Smell like that of Lactarius theiogalus. 



Underground in woods. Not uncommon. 



H. thwaitesii. — Peridium subglobose, firm, dirty white, becoming 

 discoloured here and there, up to i in. across ; internally brown 

 (spores globose, rather rough, apex with a minute papilla, 

 11-13 jx diam.). 



Characterized by the globose or subglobose spores, which are 

 either quite obtuse or minutely apiculate. 



Underground in woods. 



H. griseus. — Peridium globose or more or less irregular in form, 

 pale brown, at first covered with whitish down, up to | in. across ; 

 cavities of the gleba minute, grey, becoming blackish as the spores 

 mature (spores fusiform or spindle-shaped, irregularly warted, dark 

 umber-brown, 28-32x20 /x).- 



Varying in size from that of a pea to a small bean ; smell plea- 

 sant, resembling that of the hly of the valley. 



Among leaf-soil. Only found up to the present in Epping Forest. 



H. pusillus. — Peridium obovate or somewhat depressed, white, 

 2-3 lines broad ; sterile base large in proportion, inside dingy 

 white, cavities of the gleba large (spores broadly elliptical, with a 

 papilla at the apex, becoming slightly rough at maturity, with a 

 dull reddish tinge, 14-16x10 //). 



Strongly resembling, superficially, the sclcrotiuni called Sclero- 

 tiiim compIaniitnm. 



On mossy ground.
