longer hyphae ( ca . 50/*) have been observed bearing conidia 
singly and laterally. On Lappula virginiana. Somers, Ra¬ 
cine and Blue Mounds. While this fungus causes conspicuous 
spotting of the leaves the conidia are inconspicuous and evan¬ 
escent. I have had it under observation for a number of 
years expecting at some time 1 to secure specimens with a more 
profuse development of conidia. A specimen collected at Blue 
Mounds, July 13, 1912, is taken as the type. A more recent col¬ 
lection made at Potosi bears conidia up to 30/x in length. The 
Wisconsin fungus seems to be closely allied to var. symphyti- 
tuberosi, Allesch. ( Hedwigia, 1894, p. 73.) These specimens 
differ from Hermodendron farinosum Bon. as figured (Bot. 
Zeit., t. VIII, fig. 9) in the longer and narrower conidia and the 
absence of the two guttulae in the lower members of the chain. 
During August and September, 1912, there was collected at 
Madison on leaves of Ribes americanum a fungus of which the 
following notes were made: ‘ ‘ Spots angular, limited by the vein- 
lets, often confluent into irregular areas, brown, 2-5 mm. in di¬ 
ameter; conidiophores hypophyllous in scattered tufts, closely 
fasciculate from a prominent sclerotioid base, hyaline, often 
toothed, 30-65x2-3/*; conidia terminal and lateral, hyaline, 
cylindrical, abruptly acute or rounded at each end, occasionally 
with a median septum, 20-50x3-4/*. The tufts usually have 
more or less of a pink tinge. Large fasciculi have a marked 
stilboid appearance. ’ 9 Leaves bearing the fungus were wintered 
out of doors and the following May were found to bear heads of 
conidia up to 250/* or more in diameter of a vinous purple color 
with the conidiophores compacted into blackish stipes usque 150/* 
high each springing from the summit of a plectenehymatous 
pseudopycnidium. The conidia borne on these heads were hya¬ 
line, catenulate, fusoid, continuous, 10-18x3^/*. With these 
were fasciculi, snow white to purplish, of the mucedine type and 
occasional broader ones more tubercularioid in appearance. 
Accepting the coremium structure as the climax development 
of this fungus I have labeled the specimens Graphiothecium 
vinosum n. sp. and as it appears to be at least a facultative par¬ 
asite have given it a place in this list. 
Ramularia calthae Lindr. Specimens having the follow¬ 
ing characters have been referred to this species. Spots small,
