 Soc, Vaudoise Sci, Nat, 52: 461-464, PL 1, fig. 1. 1919. — The author describes and figures 

 a specimen of Cordyceps, not altogether intact, collected in the Forest of the Jorat, that is 

 probably to be referred to Cordyceps capitata (Holm.) Link, in spite of some variations from 

 the description of this form. An interesting characteristic of the fungus is found in the 

 filamentous ascospores becoming septate toward maturity, the segments later becoming 

 disarticulated. The discharge of the ascus is accomplished by the ascus wall becoming gelati- 

 nous from the base upward, releasing the spore segments, often in a manner permitting 

 the original linear arrangement of the latter to be perceived. — Charles Drechsler.

 1919. — Phoma occulta DesmaziSres is a typical Sclerophomella, closely related to S. verbascicola 

 (Schw.) V, H., and is named S. occulta (Desm.) v. H, It is the conidial stage oi a, Pleospora, 

 probably P. vagans Niessel or P. infectoria Fckl, Sphaeria leptidea Fr, is not, as stated by 

 Vleugel, the conidial stage of Lophodermium melaleucum (Fr.) de Not., nor is it a Sphaerella, 

 as assumed by Ftjckel. ChaetopyrenaS&cc. 1883 is antedated by Passerini's genus of the same 

 name published in 1881, On the type specimen of C. hesperidum Pass, occurs a Ceuthospora. 

 Gibelli and Penzig have confounded these 2 different fungi and consequently the valid genus 

 Chaetopyrena Pass, is not given in the Syll. Fung. Ceuthospora phacidioides f. Citri Penz, 

 cannot be considered identical with Chaetopyrena hesperidum Pass, Sclerochaeta v. H. 1917 

 erected on Phoma penicillatum Fuckel is identical with Chaetopyrena Passerini. Therefore 

 C. hesperidum Passerini should be called C. penicillatum (Fuck.) v, H,; it is the imperfect 

 stage of a Pyrenophora. Pyrenochaeia destruciiva MacAlp, may be a related Chaetopyrena. — 

 Phyllosticta Rosae Roberge is discarded, P. Rosae Desm. is probably identical with P. 

 Rosarum Pass., which is apparently based on the speTmogonia, oi Phragmidium subcorticium. 

 Phyllosticta rosicola Massalongo is shown to be a Stictochorella v. H. and probably belongs to 

 Sphaerella rhodophila Passerini. Phoma exigua Desmazieres is discarded. Hendersonia 

 (Piestospora) smilacina Desmazieres is referred to the genus Cylindrophoma as C. smilacina 

 (Desm.) V. H. The genus Plenozythia is referred in von Hohnel's system of the Fungi Imper- 

 fecti to the Sphaerioideae-ostiolatae next to Macrophoma. All forms of brownish, or olive- 

 brown color, even if soft-fleshy, are placed in the Sphaerioidaceae. Forms with hyaline 

 pycnidia having a brown beak are referred to the Sphaerioidaceae, The same procedure is 

 adopted for the Sphaeriaceae and Hypocreaceae, Sphaeria Leguminis-Cytisi Desmazieres 

 is referred to Diplodina Leguminis-Cytisi (Desm.) v. H, Ascochyta Laburni Sacc, and 

 Diplodina Lahxirni Brun. are probably only forms of D. Leguminis-Cytisi (Desm.) v. H. As
