2. Scutiger retipes (Underw.) 



Polyponis retipes Underw. Bull. Torrey Club, 24 : 85. 1897. 



The type collection of this species was made in Alabama in 

 1897 by Mrs. F. S. Earle. The plants were found in autumn 

 growing on the ground in pine woods. Collections were made 

 later in Alabama by Earle and Baker. In color and stature this 

 species resembles specimens of Polyponis ovinus sent from Upsala 

 to Kew, but the pores are very much larger and the species are 

 very distinct. 



3. Scutiger decurrens (Underw.) 



Polyponis decurrens Underw. Bull. Torrey Club, 24: 83. 



1897. 



This is a very distinct species, about which little is known. 



The type plants were collected by Dr. Hasse near Pasadena, Cali- 

 fornia, growing in the soil on the side of a caiion. The collection 

 was made in February, 1896, and no new collections of the spe- 

 cies have been reported since. 



4. Scutiger cryptopus (Ell. & Barth.) 



Polyponis cryptopus Ell. & Barth. Erythea, 4: 79. 1896. 



A very distinct and interesting species found by Bartholomew 

 in Kansas attached to dead grass roots in sandy pastures. The 

 name refers to its habit of lying flat on the ground and thus con- 

 cealing the stipe, in which position the pilei look like small whitish 



discs. 



5. Scutiger laeticolor sp. nov. 



A thick central-stemmed plant of rather large size with a 

 smooth red pileus and orange-colored tubes. Pileus circular in 

 outline, depressed at the center, 10 x 10 X i cm. ; surface gla- 

 brous, brick-colored to purplish-red, margin acute, at first inflexed, 

 irregularly undulate : context fleshy-tough, pale rose-colored, 

 homogeneous, 0.75 cm. thick ; tubes 1-2 mm. long, 5 to a mm., 

 decurrent, rather dark orange throughout, mouth subcircular or 

 polygonal, dissepiments thin, toothed at times, especially when 

 decurrent : spores ovoid, smooth, hyaline, copious, 4 x 5-6 p. : 

 stipe short, thick, increasing upward, 2 x 1-2.5 cm., resembling 

 the pileus in color, but solid, firm and tough, with darker flesh. 



The above description is made from a rather old and some- 

 what faded dried specimen collected by Underwood in Alabama in
