Among mosses on gravelly hillsides. Pasadena, California. 
January. . McClatchie. 
This species is variable and somewhat ambiguous between 
Naucoria, Galera and Tubaria, but the attachment of the lamellae 
indicates a close relationship to the genus Zudaria. From Naw- 
coria melinoides, which it much resembles, it may be separated by 
its paler stem and smaller spores and by the tendency of the 
pileus to become centrally depressed or umbilicate. From Nau- 
coria pygmaca and Galera pygmaco-affinis it may be distinguished 
by its yellowish stem and adnate or decurrent lamellae. 
CORTINARIUS INTRUSUS. 
Pileus fleshy, rather thin, convex, then expanded, glabrous, 
somewhat viscid when moist, even or radiately wrinkled on the 
margin, yellowish or buff, sometimes with a reddish tint, flesh 
white; lamellae thin, close, rounded behind, at first whitish or 
creamy white, then cinnamon, often uneven on the edge; stem 
equal or slightly tapering either upward or downward, stuffed 
or hollow, sometimes beautifully striate at the top only or nearly 
to the base, minutely floccose when young, soon glabrous, white; 
spores broadly elliptical, brownish cinnamon, .00024 to .0003 1% — 
long, .00016 to .0002 broad; pileus 1-2.5 in. broad; stem 1-3 
in. long, 3-6 lines thick. 
Mushroom beds, manured soil in conservatories or in plant 
pots. Boston, Massachusetts. R. Macadam. Haddonfield, New 
Jersey. C. McIlvaine. : 
This interesting species is closely allied to Cortinarius mult : 
Jormis and belongs to the Section Phlegmacium. It has a slight 
odor of radishes and is pronounced edible by Mr. Mcllvaine. i 
habitat is peculiar, but it possibly finds its way into conservatories E 
and mushroom beds through the introduction of manure OF soil, i 
or leaf mold from the woods. It seems strange, however, that it 
has not yet been detected growing in the woods or fields. Hebe- 
loma fastibile is said sometimes to invade mushroom beds, and ot : 
plant resembles it in so many particulars that it is with some hes 
tation that I separate it. The chief differences are in the oe 
and spores. The former, in Hebcloma fastibile, is described as solid 
_ and fibrous-squamose and the latter as 10x 6 micromillimeters #
