Mycena strobilinoides Pk. — This was a most satisfactory 

 find, and made it possible to record the character of this species 

 in detail. Peck described it from the Olympic Mountains, 

 Washington. It is a striking little plant, about 3-4 cm. tall, 

 with a "flame-scarlet" (R.) pileus, and an "orange" stem; the 

 gills are colored "light salmon-orange" with a flame-scarlet edge. 

 The spores are elliptical, smooth, hyaline, and measure 7-8 x 

 5-5.5 IX. The sterile cells on the edge of the gills are broadly 

 clavate, not very much larger than the basidia, but are colored 

 fiery-orange, and their surface is echinulate-dotted; similarly 

 decorated sterile cells, less highly colored, are scattered through 

 the hymenium elsewhere, and although they have the size of 

 basidia they are clearly differentiated by these markings. This 

 is a case, entirely apart from other findings, which supports 

 Buller (7, p. 279) in his contention that paraphyses are always 

 paraphyses and here these sterile cells are surely of the nature 

 assumed by him, i, e. they are "paraphyses" and never become 

 basidia. No types of cystidia are present. This collection grew 

 on needle beds of the Douglas fir. 



Mycena pterigena Fr.  — This dainty little plant, beauti- 

 fully illustrated in Fries, Icones, Plate 85, Fig. 4, occurs in this 

 country in the Eastern mountains as well as in the West. I have 

 collected it in the Adirondacks and then again at Mt. Hood. 

 It was attached to dead fern fronds lying on the ground. The 

 pileus is only 2-5 mm. broad, scarcely higher, and at first deli- 

 cately rose-tinted. At maturity or in age the pileus becomes 

 grayish-brown either entirely or only on the umbo; it is at 

 first subcylindric-subconic, then subhemispherical, and the mar- 

 gin is pellucid-striatulate when fresh. The gills are distant, 

 ascending, rather narrow, whitish. The stem is 3-4 cm. long, 

 half a millimeter or less in thickness, filiform, tough, flaccid, 

 becoming grayish-brown after the rosy tints fade, and is attached 

 by small hairs at the base. The spores measure 8-10 X 4-4.5 fx, 

 and are oblong or oblong-subfusiform and hyaline. The surface 

 layer of the pileus is composed of large horizontal hyphae. 



Mycena tinctura, sp. nov. (See Plate IX.) — Pileus 1-2.5 cm.
