OCHRH-SPORED AGARICS. I'll 



Crepidotiis applanatiis Ir., i^ a Liiuci >pcrciL>, >hflving and often 

 inibrii.ati.J. Crcpidotus tulvutoraentosus Pk., is a pretty species witli a 

 tomentose cap and tawny scales, usually occurring: singly. It is 

 closely related to C t\ilolcpis Fr. 



Figure i so is from plants of Crcpidutiis irrsiitiis Pk., (No. 2732 

 C. U. herbarium) collected on rotting wood at Freeville, N. V., ei^iit 

 miles from Ithaca. The plants are represented twice natural size. 



CORTINARIUS Fr. 



The genus Coiiiiiariiis is chietlv distinguished from the other 

 genera of the ochre-spored agarics by the presence of a spider-web- 

 like (arachnoid) veil which is separate from the cuticle of the pileus, 

 that is, superficial. The gills are powdered by the spores, that is, 

 the spores fall away \\ ith difficulty and thus give the gills a pulveru- 

 lent appearance. The plants are fleshy and decay easily. It is 

 necessary to have plants in the young as well as the old state to 

 properly get at the characters, and the character of the veil is only 

 seen in young or half-developed specimens. The species are to be 

 distinguished from other ochre-spored agarics with a cobwebby veil 

 by the fact that the \eil in Corfifuriiis is superficial and the gills pow- 

 dery. The number of species is very large, and they are dififlcult 

 to determine. They mostly occur in Northern countries and in the 

 autumn or late summer ; some species, however, occur during early 

 summer. Peck, 23d Report, N. V. State Mus., p. 105-112, describes 

 21 species. 



Cortinarius (Inoloma) violaceus (L.) Fr. Edible. — This species is know n 

 b\- the violet or dark violet color which pervades all parts of the 

 plant. The plants are 8-10 cm. high, the pileus 7-1 5 cm. broad, and 

 the stem is bulbous, 6-8 mm. in thickness. The \eil is single. It 

 occurs in woods and open places during late summer and in the 

 autumn. Tlie flesh of the plant is also violet, and this color is 

 imparted to the liquid when the plant is cooked. Tlie flavor is said 

 to be something like that of Aii;jriciis cjiiipesfris. 



Cortinarius (Myxaciumj collinitus (Pers.) Fr. Edible. — This is known as 

 the smeared cortinarius because of the abundant glutinous substance 

 with which the plant is smeared during moist or wet weather. It grows 

 in woods. The plants are 7-10 cm. high, the cap 5-8 cm. in diameter, 

 and the stem is 8-12 mm. in thickness. It is usually known by the 

 smooth, even, tawny cap, the great abundance of slimy substance 

 covering the entire plant when moist, and when dry the cracking of 

 the gluten on the stem into annular patches. 



The pileus is conve.x to e.xpanded, smooth, e\en, glutinous when
