Davis—Notes on Parasitic Fungi in Wisconsin — IX. 261 
A parasite that is probably conspecific with Septogloeum con¬ 
volvuli Ell. & Evht. was collected on Convolvulus spithamaeus 
at Tomahawk August 22, 1919. The small, circular, pale brown 
spots are clustered on dead or dying leaf areas. The hyaline, 
straight, cylindrical sporules are 24-36x3-3%ju, becoming triseptate. 
Ramularia tenuis n. sp. 
Spots yellowish, becoming black with age, subcircular to angular, 
immarginate, 2-lOmm. in diameter; conidiophores epiphyllous, 
densely fasciculate from a prominent stromatoid base, hyaline, 
subulate to cylindrical, simple, continuous, usually straight, apex 
sometimes oblique, 10-20x2-3%ja, conidia hyaline, cantenulate, 
usually straight, fusoid to cylindrical, acute, continuous to tri¬ 
septate, 7-37xl-3/x. On leaves of Solidago latifolia. Holcombe, 
Wisconsin. August 9, 1920. This may prove to be a form of 
Cercosprella reticulata Pk. 
Botrytis epichloes Ell. & Dearn. On Epichloe typhina growing 
on Glyceria nervata. Hannibal. 
Fusicladium ejfusum Wint. On Cary a cordiformis at Muscoda 
on both sides of the Wisconsin river. 
In these collections are spots 2-4mm. in diameter which are 
light brown above but much darker and less regular in outline 
below and also dark dead areas following the veins as well as 
indefinite marginal areas; the conidiophores are hypophyllous, 
septate, usually curved or undulate, 40-140x3ju, in places swollen 
to 5/x thick; the conidia are obovate to fusoid or amygdaliform, sub¬ 
truncate at base, continuous, 13-23x6-7/x. The host tissue affected 
becomes friable. Fusicladium caryigenum Ell. & Langlois is per¬ 
haps the same parasite. 
Fusicladium cerasi (Rabh.) Sacc. (Cladosporium carpophilum 
Thuem.) On fruit of Prunus americana. Caryville and Durand. 
This was abundant on wild plums in August', 1920. Venturia 
cerasi Aderh. is said to be the ascigerous stage (Ann. My col. 16: 
81). Dr. G. W. Keitt informs me that the conidial form has been 
observed on cherries and also on leaves in Door county. 
Cercospora moricola Cke. On Morus rubra. Millville. Conidia 
40-75x3-3%/a, becoming 3-6 septate; spots immarginate, indefi¬ 
nite below.
