throughout, the gills becoming ochraceous with age. Such plants are- 
figured by Rolland, Atlas Champ., PI. 52, fig. 113. Perry’s woods, Aug¬ 
ust, Algoma. 
Mycena rugosa Fr. On decayed logs, Melchior’s woods, Novem¬ 
ber, Algoma. 
Mycena succosa Pk. On coniferous logs, Krohn’s Lake, Septem¬ 
ber, Algoma. 
Omphalia campanella Batsch. On logs, May to September, Maus- 
ton, Kilbourn and Algoma. 
Omphalia epichysium Pers. The pileus is funnel shaped, smoky- 
gray, 2-3 cm. broad. Krohn’s lake, Dvorak’s, August, Algoma. 
Pleurotus applicatus Batsch. On wood, Schmeiling’s woods, Aug¬ 
ust, Algoma. 
Pleurotus angustatus Berk. On decayed logs and stumps,, 
Schmeiling’s swamp, June, Algoma. 
Pleurotus cornucopioides Fr. The gills form ridges running down 
the stem, which is roughly strigose at the base. The spores are lilac- 
colored in mass as are those of P. sapidus. Figures by Paulet, Icon. 
Champ., PI. 28, and Boudier, leones Mycol., no. 374, resemble our forms. 
On stumps and logs, Otto’s woods, August and September, Algoma. 
Pleurotus dryinus Fr. On logs, Devine’s woods, September, Al¬ 
goma. 
Pleurotus ostreatus (Jacq.) Fr. The spores are pure white in 
mass. Hussey, Illust., PL, 19, may be considered typical for our forms. 
On maple logs, September, Casco. 
Pleurotus petaloides Bull. On decayed wood among moss, Otto’s 
woods, May, Algoma. 
Pleurotus porrigens Pers. This species may become 2-3 cm. 
broad without having any indication of gills. At this stage they re¬ 
semble white discomycetes. On decayed logs, Devine’s woods, August, 
Algoma. Peck vid. 
Pleurotus sapidus Kalch. Common on logs, Fish Creek; Heuer’s 
woods, September, Algoma. 
Pleurotus serotinus Schaeff. On limbs and logs, September, Fos- 
cora. 
Hygrophorus Bresadolae Quel. In all of the young specimens 
there is a distinct veil which forms an annulus which disappears as 
the plant becomes fully expanded. Peck’s description and figure of 
H. speciosus Pk., Rep. Mus. 53, PI. 51, well represent this form, ex¬ 
cept as to the annulus. Bresadola, Fung. Mang., PI. 9, shows a rather 
permanent ring, but his figures seem to be of only partially expanded 
plants. Under tamarack along the Ahnapee river, October, Algoma.
