tion of the species; this color is lost more or less in age. The query arises, 
could it have been introduced from England in some unaccountable way 
by the English settlers of Mich.? Prof. Peck says Schweinitz reports it, but 
he thinks it likely that Pomes fraxinophilus Pk. may have been the plant 
which Schweinitz saw. Murrill reports it from Ohio, Illinois, New York 
and Louisiana. 
Pomes fraxinophilus Pk. On Ash trunks. Washt. Co., April 19, fide Pk. 
Fomitiporella Johnsoniana Murrill. “Type collected at Ann Arbor, 
Mich., on rotten deciduous logs. Sept. 8, 1894.” This is described as a new 
species by Murrill from material he found in the New York Botanical Gar- 
den. It belongs to the old genus Poria, and has a brown, stratified plant 
body and brown spores. He separates it from Poria inermis, to which it 
seems very close, by its thick-walled tubes. 
Polvporus griseus Pk. On the ground in low woods, Wayne Co., Sept. 5, 
fide Pk. This has hitherto not been reported west of New York. I found 
it on two successive summers in the same woods. It is easily known by its 
central stem, lilac to ashy or pale gray color, and rather soft context. 
Polvporus caesius (Sohrad.) Fr. On rotting logs, probably of elm. Whit- 
more Lake, Washt. Co., Nov. 2, leg. C. H. Iv. This is a very interesting 
plant because of its spores, which are sordid blue in mass. It is uncommon. 
Dr. Farlow, to whom it was submitted, kindly sent me a specimen from the 
Krieger collection of Saxony, Germany. This agreed in all respects with 
our plants. It was labeled Polyporus caesius Fr. Prof. Peck also referred 
it to P. caesius, and was corroborated by C. G. Lloyd who happened to be 
with him. It is also reported by Murrill under the new name Tyromyces 
caesius (Schrad.) Murrill. I think it worth while to append the description 
of our specimens. 
Pileus thick, dimidiate, sessile, convex, fleshy-coriaceous, becoming hard 
on drying, pale brownish-buff becoming ashy-tinged, surface densely tomentose 
with rather long hairs, becom ing strigose-rugose, obscurely or not at all zonate, 
5-8 cm. wide, 3-4 cm. long, 1.5-2 cm. thick. Context pure chalk-white, 
soft when fresh then hard and brittle. Tubes .5-1 cm. long, small, white 
becoming cinereous; mouths at first white-stuffed then round, dissepiments 
separating and becoming lacerate, finally labyrinthiform, and colored by the 
spores. Taste and odor not noticeable. Spores 4-5.5 by 1-1.5 micr.. 
slightly curved, deep bluish-slate color in mass, subhyaline by transmitted 
light, shed copiously when plants are fresh. 
It is evident as Dr. Farlow pointed out, that this does not conform with 
the descriptions published by the British mycologists and by Saccardo and 
Fries (Hymenomvcetes Europaei.) These authors refer to the surface as 
“silky” and give the spore measurements as 13 or 14 micr. long. It would 
be interesting to see some of their plants.
