Mycena cyaneobasis Peck. Pileus 7-20 mm., conical to sub- 

 campanulate, often deep blue or brownish blue when young, 

 usualh" fading to gray or dingy white when older or in drying, 

 margin striate. Lamellae white or grayish, close, narrow, adnexed. 

 Spores white, subglobose, 6-S microns. Stipe as much as 11 cm. 

 long, whitish above, pale brownish below, mycelium at the base 

 often blue. The plants were growing in leaf mold in woods. May. 



Marasmius semihirtipes Peck. Pileus 1-2 cm., reddish 

 brown becoming alutaceous, glabrous, margin sometimes striate. 

 Lamellae white, narrow, subdistant, adnate. Stipe 3-5 cm. XI 

 mm., brown or reddish-brown, velvety-tomentose at base to nearly 

 glabrous above. Growing among old leaves and grass. June. 



Marasmius scorodonius Fr. Pileus 1-1.5 cm., iDay or reddish 

 brown, convex then plane, dry, glabrous, even. Lamellae whit- 

 ish, narrow, subdistant, interspaces venose. Stipe 2-3 cm. long, 

 blender, horny, dark brown below to pallid at apex, hollow, 

 smooth, polished. Growing in grass at base of pine tree. May be 

 readily recognized by its odor of garlic when fresh. July. 



Hard in his mushroom book (p. 144, Fig. 109), gives an excel- 

 lent illustration of this species. He also describes Russula ochro- 

 phylla (p. 187) and Marasmius semhirtipes (p. 145). In none 

 of these cases, however, does he state that the plants were col- 

 lected in Ohio. It has been thought advisable, therefore, to report 

 them at this time as members of the Ohio flora. 



AN OHIO STATION FOR MITREMYCES CINNABARINUS. 



WiLMER G. Stover. 



During the early part of April, Mr. B. W. Wells brought into 

 the laborator}^ several specimens of Mitremyces cinnabarinus 

 Desv. which he had collected near Gibsonville, Hocking County. 

 A specimen in the state herbarium shows that the species had been 

 collected near the same place, April 5, 1910, by Prof. R. F. Griggs. 

 The plants were growing in leaf mold in a deep ravine among 

 hemlocks, tulip-trees and undergrowth. 



Morgan* refers all the American plants of this genus to M. 

 lutescens Schw., but had no Ohio specimens. Lloydf states that 

 its range is from Massachusetts to Florida and that it does not 

 extend into the Mississippi basin. Hard| gives an illustration 

 but says that while he has seen it growing in the mountains of 

 West Virginia he has never collected it in Ohio. So this is the 

 first the plant has been found in the central West.
