 the pedicel shorter than the spore.

 Professor Jones observes that this fungus destroys the leaves it 

 attacks. 



/ICciniUM Sarcop.ati. —Spots merely a tliickened portion of the 

 niatrix ; peridia el()n:4ate(l, cylindrical, crenate lacerate at the ajiex, 

 orange colored ; spores subglobose, .0008-. 0009 of an inch in diame- 

 ter. 



Living leaves of Sarcohatits vcnniculatus. Utah. June. Jonc;. 

 The briglit orange-colored elongated peridia make this a showy 

 species. The cells of the ])eridia are pentangular or occasionally 

 hexangular and contain highly colored oil globules. The spores in 

 the dried specimens are whitish, but they may have been more high- 

 ly colored in the fresh state. 



SvNCHYTRiUM JoNESii.T — ubcrcles rather large, unequal, promi- 

 nent or somewhat depressed, hypophyllous, reddish-brown, the epi- 

 dermis at length rupturing irregularly ; spores globose, smooth, red- 

 dish brown, .0003-.0004 of an inch in diameter.

Li the color of the spores this species does not strictly agree with 

 tlie gene-ic character, but in other respects it is so good a Synchy 

 trium that I have thought it best to refer the fungus to that genus. 

 'I'hc s])ecies is dedicated to its discoverer, Prof. M. E. Jones. 



NoTK. — Since the publication, in Thf. Botanical Gazhftk, Vol. 

 IV, p 170, of the description of Bovista spinulosa, I have received, 

 trom Dr. 1. L Brown of Wisconsin, a mature sjiecimen which shows 

 ihat the peridium ruptures in a stellate manner and that therefore the 

 lungus shf)uld be referred to the genus Mycenastrum. The descrip- 

 tion needs the following revision : 



Mycenastrum spinui.osum. — Peridium globose, sessile, two to 

 four inches in diameter, thick, firm, whitish, becoming tinged above 

 with \ellow and nrown and externally cracking into rather large areas, 

 the whole Iwown when mature and stellately splitting from above into 

 six or seven unequal spreading or reflexed rays; capillitium and 

 spores in the mass dark-brown with a slight purplish tinge; flocci 

 rather short, pale, usually branched, armed with scattered unecjual 

 aculei which are more numerous near the acuminate extremities ; spores 

 tdobose,- colored, minutely wartcd, .0004-.0005 of an inch in diam- 

 eter. 



The species may be distinguished from AT. C/iilense, to wdiich it 

 is allied, by its paler and globose i)eridium and by its larger and glo- 

 bose spores. 



I have also received from Mr. C. G. Pringle of Vermont, fresh 

 specimens of the fungus described in Vol. V, p. 35, under the name 

 Pczha spongiosa. These show by their texture that the fungus should 

 be referred to the genus Bulgaria, with the following description :
