The form in Fungi Columb. 3779 and 438/, both on Salix Fend- 

 lieriana, incorrectly labeled Septoria Salicis West., differs from 

 all the preceding in its larger sporules. It is less distinctly macu- 

 late and almost completely epiphyllous. (Septogloeum Salicis- 

 Fendleriance sp. nov.) 



Examination and comparison of all the available material seems 

 to justify the following determinations : 



Cylindrosporium salicinum (Peck) Dearness (= Septoria sali- 

 cina Peck on Salix lucida. Acervuli mostly hypophyllous, on arid 

 centers of spots ; sporules about 38 X ?rZ- 2 S obscurely 1-3 

 septate. Ellis & Ev. N. Am. Fungi, 2646, 3064, 3369; Fungi 

 Columb. 284, 2081. 



f. albaniensis (Thiim.) on Salix lucida. Maculae less distinct; 

 sporules usually straight about 33 X 2.75-3 Seym. & Earle 

 Ec. Fungi 197; Fungi Columb. 1346. 



var. circinatum var. nov. on Salix lucida. Maculae .5-1.5 cm. 

 mostly circinate or mottled ; sporules 40 X 3—3.5 /a. This is Fungi 

 Columb, 38/2. 



Septoria Salicis West., as exhibited in Roumeguere's Fungi 

 Gallici 3843, and 6\ salicicola Sacc, in de Thiimen's Myc. Univ. 

 1993, have true pycnidia and are quite different from any Amer- 

 ican species of Septoria on willow that I have seen. In both, 

 the spots are small, about 1 mm., the pycnidia nearly black and 

 mostly epiphyllous. 



In this connection it may be worth while to report briefly the 

 results of the examination of three other allied form-species on 

 willow leaves. See No. 41.
