Ochrosporae 



slightly tapering upward, colored like the pileus, covered at the base Fiammuia. 

 with a dense white tomentum. Spores rusty-brown, globose, 5/x broad. 



Pileus 3-5 cm. broad. Stem 5 cm. long, 4-6 mm. thick. 



Gregarious on partly burned anthracite coal, Mt. Gretna, Pa. Sep- 

 tember. C. Mcllvaine. 



The species is peculiar in its color and habitat. In the dried speci- 

 men the gills have assumed a brown color with no ochraceous tint. 

 Mr. Mcllvaine remarks that it is an edible species, dries well, and is 

 excellent when cooked. Its relationship is with F. anomala Pk., but it 

 is a larger plant with darker color and a different habitat. Peck, Bull. 

 Torr. Bot. Club, Vol. 26, F. 1899. 



It grows on partly burned anthracite coal, not buried, as printed in 

 the Torrey Bulletin. The mycelium completely involves the pieces of 

 coal, holding them tightly in its meshes. Patches of it were strictly 

 limited to the size of the ash-pile containing the partly burned coal. 

 Quite fifty were found. 



As stated, it is edible, and it is of remarkably fine substance for a 

 Fiammuia. 



Lu'BRICl. Pileus viscid, etc. 



F. edu'lis Pk. eatable. Pileus fleshy, convex, obtuse, glabrous, 

 moist, brown, grayish-brown or yellowish-brown, sometimes rimose. 

 Flesh whitish. Lamellae rather broad, close, decurrent, bright tan 

 color, becoming brownish-rusty. Stems cespitose, equal, stuffed or hol- 

 low, brown. Spores subelliptical, 13x5-6^. 



Pileus 2-3 in. broad. Stem 2-3 in. long, 3-6 lines thick. 



Grassy ground, along pavements, in gutters and by the side of wooden 

 frames of hotbeds. Haddonfield, N. J. October. C. Mcllvaine. 



The collector of this species informs me that the flavor of the fresh 

 plant is slightly bitter, but that this disappears in cooking and the fungus 

 furnishes a very good and tender article of food. Successive crops con- 

 tinued to appear for a month. In the dried specimens the stem is 

 striate. Peck, Bull. Torr. Bot. Club, Vol. 24, No. 3. 



This new species appears annually in the same place. I have not 

 found it elsewhere. It is meaty and excellent.
