46 THE AGARICACEAE OF MICHIGAN 



more iu diameter and the stem very stout. The descriptions in the 

 books are very meagre, and no mention is made of the change of 

 color on drying. The dried specimens are elegant. Its flesh is not 

 very tough and it is easily mistaken for a Pleurotus. The gills are 

 very broad in large specimens, not truly distant, and are usually 

 distinct on the stem or anastomose only in an obscure manner if 

 at all. Some specimens are almost lateral, growing in a somewhat 

 ascending-subhorizontal position, but with a marginate pileus; 

 others have a subcentral stem. This is not Lentinus strigosus 

 Schw., a species which seems to be synonymous with Panus rudis. 

 Some consider P. laevis B. & C. to be the same as P. strigosus.

Epicrisis, 1836-38.

PILEUS 2-7 cm. broad, irregular, eccentric or sublateral, ascend- 

 ing, depressed or vase shaped, sometimes infundibuliform, cuneate- 

 rounded when young, tough, villose-velvety or strigose, alutaceous 

 to reddish brown, margin often lobed, incurved. GILLS narrow, 

 crowded, decurrent, pallid or tinged with the color of pileus, pube- 

 scent, edge entire. STEM short, eccentric, sometimes almost lack- 

 ing, rillose, concolor. SPORES elliptical-oval, 5-6 x 2-3 micr., 

 smooth, white. TASTE slightly bitter at times. ODOR none. 



Caespitose-crowded. Everywhere in town and country, on 

 stumps, logs, dead branches, trunks, etc., of frondose trees. Through- 

 out the state. May to November. Very common. 



This is Lentinus lecomtei of many American notices, not the true 

 L. lecomtei Schw. which has serrate gills. Our plant has entire 

 gills. Schweinitz described the true L. lecomtei from a specimen 

 sent from Georgia by Lecomte. (See Lloyd, Myc. Notes, Vol. I, 

 p. 60.) It is also Lentinus strigosus Schw. to which Peck refers his 

 specimens. Peck says it was found in one case on a balsam fir 

 trunk, while ordinarily it is limited to deciduous trees. Patouil- 

 lard says the gills of P. rudis are serrate, which is a rather remark- 

 able statement. It can be used for flavoring gravies and dries well 

 for winter use, but is readily attacked by beetles.
