JOURNAL OF MYCOLOGY. 
VOL. IV, Nos. 4, 5, 
SpHvEROTHECA humuli (DC.) Burrill.—On Agrimoniaeupatoria (Mis¬ 
souri); Geum macrophyllum ( Wisconsin). 
Spha;rotiieca mors uv,e (Schw.) B. & C.—On Ribes rotundifolium 
(Missouri). The perithecia were found only on the fruit. 
SphyEiiothpica pannosa (Wallr.) Lev.—On Rosa lucida and culti¬ 
vated Roses (Missouri). In our specimens, the appendages are colored 
near the base, as described by Tulasne (Fung. Carp. Select., I, page 208). 
Spelerotiieca pruinosa, C. & P.—On Rhus copallina (Missouri). 
This species was collected in southern Missouri in 1886 and it agrees very 
well with the published description of the authors. 
Sph^erotheca lanestris, Hark.—This remarkable species was 
taken near Napa City, California, upon the young shoots of Quercus 
agrifolia. The tree from which the specimens were obtained was a large 
one, the trunk being fully two feet in diameter, and its peculiar appear¬ 
ance attracted attention a considerable distance. The dense mycelium 
completely covers the young leaves and twigs, causing the former to 
shrivel and cease growing before they attain one-fourth their usual size. 
The perithecia are frequently overlooked as they are buried in the dense 
mats of mycelium. 
Podosph-ERA oxycantiiyE, DC.—On Amelanchier Canadensis , Pru- 
nus domestica, Primus cerasus , Spircea , Cratcegus crus-galli (Missouri); 
Crataegus oxycantha (Wisconsin); Prunus demissa (Colorado and Utah). 
The form on Spiraea agrees with the published specimen in Ellis North 
American Fungi distributed as Microsphcera. 
Erysiphe cichor ace arum, DC.—On Verbena urtmefolia , Verbena 
hastata , Plantago major , Ambrosia trifida, Ambrosia artemiscefolia , Verno- 
nia noveboracensis , Helianthus annuus, Galium apavine (Missouri) ; Aster 
corymbosus , Hydropliyllum Virgmicum , Inula helenium , Phlox paniculata 
(Wisconsin); Solidago Canadensis , Stachys palustris , Dysodia chrysanthe- 
moides , Verbesma enceliodes , Iva xanthiifolia (Colorado); Rudbeckia occi¬ 
dentalism Helianthella Parryi , Mimulus luteus , Humulus lupulus , Mertensia 
Sibenca , Ambrosia psilostachya (Utah). It is seen that several of the 
hosts named above upon which this widely distributed species occurs are 
new, and yet in all the specimens examined we find the characters as set 
forth by Burrill and Winter quite constant throughout. 
Erysiphe communis (Wall.) Fr.—On Pniace, cult., Dahlia , cult.. 
Pea , cult., Pliaseolus perennis , Phaseolus helvolus (Missouri) ; Astragalus 
Canadensis , Geranium maculatum , Clematis Virgmiana, Aquilegia Cana¬ 
densis (Wisconsin); Thermopsis Montana , Trifolium involucratum, Clematis 
ligustifolia (Colorada); Lathyrus polymorphic, Lupinus argenteus, var. argo- 
phyllus , Astragalus junceus , Astragalus Canadensis , Thermopsis (Utah); 
Ranunculus cymbalaria (Nevada). 
Erysiphe tortilis (Wallr.) Winter.—On Cornus sanguinea (Mis¬ 
souri). 
Erysiphe galeopsidis, DC.—On Scutellaria parvula (Wisconsin).
