366 MORPHOLOGY, ETC., OF FUNGI, ETC. [Bot. Absts. 



here is likened to the heterospory in various rusts. Other cases are given as follows: Phleo- 

 spora Aceris Sacc. is accompanied by Phyllosticta Platanoides Sacc. which at an intermediate 

 stage has been called Leptothyrium Platanoides. Phleospora Ulmi Wallr. is accompanied by 

 an apparently unnamed Phyllosticta. Septoria Podograriae is frequently accompanied on 

 the same spot by Phyllosticta Aegopodii Allesch. At one stage this has been placed in Cylin- 

 drosporium. All these fungi appear to develop later into species of Mycosphaerella. Klebahn 

 showed that Phleospora Ulmi is the pycnidial stage of Mycosphaerella Ulmi. Jaap proved 

 the same for P. Oxycanthae and M. Oxycanlhae. P. Aceris is often accompanied by a form 

 which is probably M. septorioides (Desm.). Phyllosticta Aegopodii and Phleospora Podagra- 

 riae are almost certainly M. Aegopodii. This is all held to show the closely knit relationship 

 of the groups in the third volume of Saccardo's Sylloge and how necessary it is to have a term 

 (Coelomycetes) to include them all. The futility of calling spores "sporulae" in one group 

 and "conidia" in another is shown. Cultures are desirable to prove the above absolutely, 

 but when these forms occupy a definite "spot" on the mycelium and the phenomena reoccur 

 frequently, the result is practically equivalent to a pure culture. 



II. Sphaeridina inlermixta (B. & Br.) and its Allies. Material collected at Birmingham 

 on Rubus and on Rosa damascena throws light on the relationship of Sphaeria intermixta 

 Berkley & Broome, with hyaline spores, and S. abbreviata Cooke with "pale brown" spores 

 in lineally aggregated perithecia. The evidence tends to show that these two species differ 

 solely in the "arrangement of their perithecia (a difference which future observations may 

 entirely remove), and that they probably constitute one species (S. intermixta) occurring in- 

 discriminately on Rosa and Rubus, and having in addition on Rubus a var. abbreviata (Cooke) ." 

 Cook's statement that the spores were "pale brown when mature" was probably a slip of the 

 pen. The older material on Rubus showed larger spores and increased septation. The 

 younger less complete form is probably the Metasphaeria sepincola (Fckl.) Sacc. on Rosa and 

 Rubus, and possibly the Sphaeria sepincola of Fries. The later 5-6 septate stage is probably 

 M. brachytheca (B. & C.) Sacc. on Rosa. Material on Rosa damascena was in all respects like 

 Sphaeridina intermixta except in the larger more septate spores. This could be only a later 

 stage of this species. The fungus on Rosa damascena is here described as S. intermixta i. 

 valde-evoluta f. nov. Incidentally it is interesting that just as Cook recorded his S. abbre- 

 viata as accompanied by Hendersonia Rosae (= H. Rubi?), so the fungus on R. Damascena 

 was accompanied by what is usually called Hendersonia Rosae, though because of the pres- 

 ence of one or two longitudinal septae this latter material becomes technically a Camaro- 

 sporium as many Hendersonias do. "In fact this increase of septation as the spores of Coelo- 

 mycetes and Ascomycetes become older and longer is a very common phenomenon, though 

 its occurrence and its fundamental influence on future taxonomy is only just beginning to 

 be recognized." — K. M. Wiegand.
