THE SAPROPHYTIC FUNGI OF EASTERN IOWA. ^q 



stipes raising the sporocarps an inch or two above the sur- 

 face. The peculiar brown translucent conical spines consti- 

 tute the "gems" with which the upper surface is clothed. 

 These fall off so as to leave white round scars, which to the 

 naked eye assume a reticulate pattern. A form occurs in 

 which the spines are sharper, more abundant, black or dark 

 brown in general effect against a gray inner peridium. but 

 otherwise as above. This appears to be L.ferlatum Pers. It 

 mav be esteemed a recognizable variety. 



8. LVCOPERDON PEDICELLATUM Peck. 



Sporocarp globose or broadly ovoid. %—2 inches in diameter, 

 narrowed into a stem-like base, with a slender fibrous mycelium. 

 Outer peridium gray changing to smoky brown, consisting of 

 long rather dense spines convergent at the apex; these at length 

 fall away, leaving a wrinkled or obscurely reticulated surface to 

 the pale glabrous inner peridium; sterile base small, occupying 

 about a fourth part of the peridium; mass of spores and capilli- 

 tium greenish-yellow then brownish; threads much branched, 

 main stem thicker than the spores; spores globose, smooth, 

 3-4.5 « in diameter, with persistent pedicels three to five times 

 as long. 



Growing on the ground and decaving wood in the woods. 

 Instantly recognized bv the long, persistent, pedicels of the 

 spores. Superficially the species resembles some phases of 

 the preceding species but is distinguished bv the converging 

 spine-tips. Not uncommon. September. 



9. LVCOPERDON" PUSILIAJM Bdtscll. 



Sporocarp small, less than an inch in diameter, globose ses- 

 sile, rooted; the outer peridium a thin coat of minute granules 

 or scales; furfuraceous, inner peridium pale, exceedingly thin, 

 papery but tough withal; gleba greenish-yellow or olivaceous 

 becoming darker, the capillitial threads abundantly branched 

 about equal to the spores; sub-gleba small but distinct, coarsdv 

 cellular; spores globose, nearly smooth, 4 u. 



Xot common; occuring occasionally in old fields or undis- 

 turbed woods in small colonies, half a dozen individuals in a
