dying from root troubles, the cause of which is unknown to the writer 

 who would hesitate to lay the cause definitely to this fungus. The symp- 

 toms of the diseased condition in these trees began by a slight yellowing 

 of the foliage and reddening of the bark. The last year before the fruit- 

 ing bodies of Hypholoma fasiculare appeared at the crown of the trees 

 they bore a bumper crop but when tested they could be easily pushed, 

 over, for the roots were almost entirely decayed next to the crown. Mc- 

 AlpineS has reported Hypholoma fasiculare to be parasitic on the roots

of raspberry and cherry in Victoria. 



155. Hypholoma capnoides Fries. 



On fence posts of Abies wood. Not commonly found; but abundant 

 where found, Corvallis. November. Nos. 1868, 2204. 



156. Hypholoma hydrophilum Fries. 



Caespitose in large clusters on moss-covered, decayed logs, Philomath. 

 November. No. 2197. 



Our plant is not H. hydrophilum Fries (sense of Saccardo). These 

 spores are 5-6 x 2.5-3 /jl and there are no cystidia. The gills' distil con- 

 siderable moisture during damp weather. 



157. Hypholoma lachrymabundum (Fries) Quel. 



In coniferous woods, Corvallis. November. Rare. Epling No. 73. 



This collection follows the description of H. lachrymabundum given 

 by KauffmanG with the exception that it may be slightly darker. The 

 spores are smooth, elliptical, not curved but flatfish on one side. 



158. Hypholoma velutinum (Fries) Quel. 



On low ground under maples, Corvallis. October. Rare. No. 2055. 



This collection agrees very well with my collection (506) of the same 

 species taken in Tower Grove Park, St. Louis, Missouri. The spores are 

 ovoid to subcitriform with a hyaline apiculum, tuberculate, dark purplish- 

 umber when mature, 10x6-7 /i. The edges of the gills distil droplets 

 darkened by suspended spores. 



159. Gomphidius oregonensis Peck. 



In damp coniferous or mixed woods, Corvallis. November. No. 2194. 



This is one of the very common Agarics which comes shortly after 

 the rains begin in the fall and may be found quite generally distributed 

 in the wooded portions of western Oregon and Washington and is 

 abundant. This was reported by Professor Lake as being a very pal- 

 atable mushroom. 



7. Family Lycoperdaceae 



160. Geaster delicatus Morgan. 



In humus soil under coniferous trees, Corvallis. October. Rare. No. 

 2047. This small species is mentioned here because it has not been re- 

 ported from Oregon.
