NOTES ON SOME SPECIMENS OF PYKENOMYCETES IN THE SCHWEINITZ 

 HERBARIUM OF THE ACADEMY. 



BY J. B. ELLIS. 



Some time during the past year (1894) there was found in the 

 Herbarium of the Academy of Natural Sciences of Philadelphia, a 

 package that had lain unnoticed for many years. The package 

 was found to contain many of the missing specimens mentioned in 

 the preface to The North Am. Pyrenomycetes. These specimens are 

 evidently authentic and reliable, the writing on the papers in which 

 they are wrapped being in Schweinitz's own hand, with the 

 abbreviation L. v. S. 1 after the names of the species described by him. 

 In only a few cases are the habitats given, but almost all are 

 marked as collected either at Bethlehem, Pa., or Salem, N. C. 

 They are all very small — many of them old and without fruit. 



From a careful examination of the specimens the following notes 

 were made to enable one to recognize some of the Schweinitzian 

 species that have hitherto been only imperfectly understood. Dr. 

 Karl Starback in his " Studier i Elias Fries Svamparherbarium:" 

 Bihang till K. Svenska Vet. Akad. Handl., Band 19, Afd. Ill, No. 

 2, 1894, has also examined some of the specimens noted and his 

 observations agree with those here recorded: — 



Chaetomium olivaceum C. & E., Grev., VI, p. 96.
