Trametes mollis Fr. Sept. Frequent. Tolland. On log 

 of Ahies lasiocarpa. Reported only on deciduous trees by Over- 

 liolts. 



Trametes piceina Pk. Sept. Infrequent. Tolland. 



Forming low, narrow, strips on decorticated fallen logs of 

 Picea. Markedly distinct from the Trametes -pini fruit-bodies 

 on the same host and in same region, by its smaller pores and 

 its resupinate-reflexed habit. (See, however, Overholts, Ann. 

 Mo. Bat. Gard., 22: 722. 1915.) 



Trametes pini Fr. Sept. Very common. Leal. Tolland. 

 On Pinus contorta, Picea Engelmanni, Ahies lasiocarpa. On 

 living or dead trunks. Large percentage of pines had heart rot. 



Trametes protracta Fr. Sept. Common. Leal. Tol- 

 land. Common on old and charred logs of Pinus contorta. This 

 is distinct from T. vialis Pk. 



Trametes serialis Fr. Sept. Rare. Tolland. On dead 

 branches of Salix sp. 



Trametes tenuis Karst. Sept. Frequent. Leal. Tolland, 

 fide Overholts. On charred logs of Ahies lasiocarpa, forming 

 extensive patches up to 20 cm. long. 



Trametes variiformis Pk. Sept. Frequent. Tolland. 

 Leal. On coniferous wood. 



Clavariaceae 



Clavaria aurea Fr. Infrequent. Tolland, Leal. 



On the ground under pine, spruce and fir. Spores subhya- 

 line, 9-12 x 4-4.5 jjl, rarely up to 15 jj, long. Size and habit 

 similar to C. flava. Color of branches "apricot-yellow" to 

 "buff-yellow" (Ridg.), with "lemon-yellow" tips. Base of stem 

 white, 10-12 cm. thick. 



Clavaria botrytis Fr. Infrequent. Tolland. 



Under spruce and pines. The spores in some specimens 

 measure shorter, and indicate slow maturity. The striations on 

 the spore wall are faint and must be looked for under magni- 

 fications of about 1500 diam. Spores of the Colorado form 

 measure 10-13 (15) x 4-5 /x. The spores of some of my Michi- 

 gan specimens measure 10-15 (16) x 5-6 //, all striate. I am
