TUBARIA W. Smith. 



In the genus Tubaria the spores are rust-red, or rusty brown 

 (ferruginous or fuscous-ferruginous), the stem is somewhat cartilagi- 

 nous, hollow, and, what is more important, the gills are more or less 

 decurrent, broad next to the stem, and thus more or less triangular 

 in outline. It is related to Naucoria and Galera, but differs in the 

 decurrent gills. The pileus is convex, or with an umbilicus. 



Tubaria pellucida Bull. This species grows by roadsides in grassy 

 places. The 

 plants are from 

 3-4 cm. high, and 

 the cap 1-2 cm. 

 in diameter, and 

 the stem 2-3 mm. 

 in thickness. 



The pileus i s 

 conic, then bell- 

 shaped, often ex- 

 panded and with 

 a slight u m b o ; 

 the color is dull, 

 reddish brown,

and it has a watery 

 appearance. The 

 plant is sometimes enveloped with a loose and delicate universal 

 or outer veil, which remains on the margin of the cap in the form 

 of silky squamules as shown in the figure. The margin of the pileus 

 is faintly striate. The gills are only slightly decurrent. Figure 153 

 is from plants (No. 2360 C. U. herbarium) collected along a street 

 in Ithaca. 



The stem is at first solid, becoming hollow, tapering above, and 

 the apex is mealy. 



CREPIDOTUS Fr. 



In Crepidotus the pileus is lateral, or eccentric, and thus more or 

 less shelving, or it is resupinate, that is, lying flat or nearly so on 

 the wood. The species are usually of small size, thin, soft and 

 fleshy. The spores are reddish brown (ferruginous). The genus 

 corresponds to Pleurotus among the white-spored agarics, or to Clau- 

 dopns among the rosy-spored ones. Peck describes eleven species 

 in the 39th Report, N. Y. State Mus., p. 69 et seq., 1886.
