dry state tlull brown to olivaceous brown, varying to a brighter reddish yellow, thin 

 and papery, in the Wyoming plain noted below, really divided into two extremelj thin 

 layers, the outer of which ma] 01 may not scale ofi in pan; the surface dotted with 

 minute, scattered, persistent Seeks <>r nodules or varying to more closely plat ed granular 

 particles. Gleba dull olivaceous brown at maturity; Bubgleba obvious to large, filling 

 the stalk-like base, about the same color as the gleba and remarkable in iis compai I 

 structure with chambers so small as to be invisible, thus easily separating this species 



from all other American species of /.v. ojnrdoti (Calvotia ruloo flaw has no chambers 



at maturity). 



Spores (of plant from Wyoming) smooth or rarely faintly dotted, spherical, 3.4 4/i, 

 with a conspicuous "il drop and sometimes a short pedicel. Capillitium threads 



branched, averaging about T7^ thick. 



Gregarious on earth in open places. We have not found it in North Carolina, but 

 it is reported from a number of eastern stales, and the < rjuiclonv.c form is said by l.loyd 

 to be common. This last form is the more spherical one without a stalk like base. In 

 plants we have from Wyoming, kindly sent us by Mr. Simon Davis, both forms are 

 well represented and apparently from the same collection. One of the plants has as 

 distinct a stalked lease as thai from Kurope shown by Lloyd on his plate 52, fig. 4. We 



have a good European specimen from Rome]] (Sweden) which agrees with the Wyoming 



plants in every particular except that the peridium does not divide into two papery 

 layers in age (spores smooth, id 4/j); also one from Ton cud ( Portugal) which is similar 

 (spores smooth, 3.S 4.2/j, rarely with a short pedicel). 



This species is closely relai ei I to /.. pusillum, and Lloy.l thinks thai they intergrade 

 With us I., pusillum is a very common little plant without subgleba, and it doesnot vary 



here to the larger forms of the above description. Its root is distinctly more slender 



than in L. polytHorpkum of the same size. Its spores are Indistinguishable, l.loyd 



shows forms of this species from Australia with several plants of a colony connected by 

 underground rhizomorphs (Myc. Notes, p. 730, fig. 1096). If is interesting to note 

 that some of our plants from Wyoming show this character clearly. 



Cunningham gives the spores of the present species as 1.5 5.,5/j. Other characters 

 agree well with the above. It is supposed bv some authors, as Hollos, that /.. poly- 

 morph urn is the same as L.furfuraccuni SchaelT., a species which is insufficiently known.
