76 THE AGARICACEAE OF MICHIGAN 



margin, tawny-red. FLESH meinbranaceus. GILLS adnate, close, 

 white. STEM 5-12 cm. long, filiform, tall, straight, equal hollow, 

 pruinose-tomentose, radicating, brown or fawn color, apex white." 

 SPORES 7-8x3.5 micr. (Pennington.) Among fallen leaves in woods. 



Rare. 



It has been suggested that this is identical with M. chordalis (Fr.) 

 Bres. I will, therefore, append Bresadola's description of that 

 species : 



"Pileus 1-2.5 cm. broad, convex, soon umbilicate, then expanded, 

 dry, umber, then livid-whitish, marked with reddish spots, pruinose 

 under a lens, with an incurved, at first striate then sulcate margin. 

 FLESH membranaceus. GILLS adnate to subdecurrent, distant, 

 whitish, at length straw yellow and reddish spotted. STEM 7-10 

 (rarely 15) cm. long, 1-2 mm. thick, straight, stuffed by a pith, (then 

 hollow), date-brown, apex whitish, densely gray pruinose, in wet 

 weather the surface is shiny from yellowish watery drops. SPORES 

 fusoid-ventricose, 8-10x6 micr., hyaline under microscope. CYS- 

 TIDIA fusoid. BASIDIA clavate, 40x1-6 micr. ODOR none." 



It is evident that here are two forms of Marasmius, clearly dis- 

 tinguishable by the colors. Specimens have been sent from Europe, 

 according to Pennington (information by letter) marked ill. chor- 

 dalis, which had the color of our 1/. elongatipes. It seems probable 

 that there are two species in Europe which are confused under the 

 one name. Bresadola's figure does not illustrate our plants and 

 Peck's name should be retained. It was originally called M. longipes, 

 a name which had been pre-empted. 



48. Marasmius papillatus Pk. 

 N. Y. State Mus. Rep. 24, 1S72. 



PILEUS 5-15 mm. broad, convex-expanded, markedly papillate, 

 striatulate on margin, dingy whitish with pink tinge, opaque, 

 slightly subtomentose or glabrous. FLESH submembranaceus. 

 GILLS broadest behind, decurrent by tooth, narrow in front, close, 

 to subdistant, whitish or tinged yellowish. STEM 2-5 cm. long, 1 

 mm. thick, equal, elastic, toughish, hollow, pruinose, pallid, tinged 

 flesh color, slightly darker below, distinctly rooting. SPORES 10-11 

 x?>-4 micr., subcylindrical, smooth, white. CYSTIDIA few, scat- 

 tered, narrowly lanceolate, about 50x5-6 micr., acuminate. 



Gregarious, on decayed, mossy logs in coniferous regions. Bay 

 View, New Richmond. July- September. Infrequent.
