Qitocybe robusta Pk. In mixed woods of birch, beech and spruce. 

 The gills are vinaceous-buff (Ridg.) when fresh, becoming army- 

 brown (Ridg.) after being dried. The pileus varies from the thick 

 and firm condition of the type. 



Qitocybe sinopica Fr. On charred soil in woods. 



Collybia albiflavida {Pk.). On the ground among decaying forest 

 debris. The character of the stem-cortex is more like Collybia than 

 Tricholoma. 



Collybia butyracea Fr. Under cedar, balsam and pine. The typi- 

 cal form. 



Collybia confluens Fr. Among fallen leaves. 



Collybia distorta Fr. Subcaespitose on conifer stump. The dis- 

 tinguishing characters are the narrow, crowded gills which soon be- 

 come rufescent-spotted, the compressed subsulcate stem and the 

 chestnut-^brown pileus soon fading to cinnamon. Spores 3-4 by 2 

 microns. Cystidia none. 



Collybia dryophila Fr. Under white pine and spruce. A variety 

 occurs with stem colored Mars-yellow (Ridg.). 



Collybia familia Pk. On mossy logs, cedar and hemlock swamps. 



Collybia. maculata A. & S. Under pine and balsam. 



Collybia stridula Fr. Low ground under conifers. 



Collybia stipitaria Fr. On needles of spruce. 



Collybia succosa Pk. On decaying wood. 



Collybia tuberosa Fr. On decayed debris including fungous 

 remains. 



Mycena clavicularis Fr. On beds of pine needles. 



Mycena epipterygia Fr. On mossy logs. 



Mycena galericulata Fr. On decayed wood in cedar swamp. Not 

 noticed elsewhere. 



Mycena haematopoda Fr. On mossy logs of cedar etc. 



Mycena immaculata Pk. On mosses and humus. 



Mycena leaiana Berk. On rotten wood. 



Mycena pelianthina Fr. In mixed woods of beech and spruce, etc. 



Mycena pura Fr. Among debris in mixed or conifer woods. 



Mycena rorida Fr. var. On and among j^ine and spruce needles. 

 These plants depart from the species in the gills being broadly adnata 

 but not decurrent and in the spore size. The spores are elliptic- 

 ovate, 7-9 by 4-5 microns. According to Ricken, the size of the 

 spores are 10-15 by 4-5, cylindric-lanceolate. 



Mycena rubromarginata Fr. var. Among forest debris under bal- 

 sam trees. The specimens found were smaller than the typical form 

 and the edge of the gills were fuscous-brown with scarcely a red
