Fitzpatrick : Monograph of the Coryneliaceae 249 



Thunbergii, P. cbstata, P. falcata, and P. gracilior. Known 

 thus far only from Africa, Japan, New Zealand (Cooke 8) and 

 the Philippine Islands, but probably occurs throughout the tropical 

 and subtropical regions of the Eastern Hemisphere. It has pre- 

 sumably also a considerably wider host range. 



There is evident in different collections of material consider- 

 able variation in the size and general appearance of the perithecia. 

 In the material from Japan they are somewhat smaller than those 

 of South African specimens. No other differences have, how- 

 ever, been correlated with these variations, and the writer believes 

 that a single species is represented. 



The material studied by the writer agrees well with the colored 

 illustrations and the description of Corynelia uberata published 

 by Acharius in the Observationes Mycologicae of Fries (12). 

 Acharius in connection with this description cites Mucor clavatus 

 L. and Sphaeria turbinata Pers. as synonyms. Moreover he 

 (Acharius 1) cites Mucor clavatus as a synonym in connection 

 with the original description of Lichen {Calicium) helophertis. 12 

 No explanation of his failure to cite L. (Calicium) helophertis 

 in the synonomy of Corynelia uberata can be given. Fries (13) 

 uses the name C. uberata in Systema Mycologicum but Saccardo 

 (45) selecting the earlier specific name of Linnaeus designates 

 the species as C. clavata (L.) Sacc. Because the latter binomial 

 has come into more common use in recent years it is important 

 that the identity of C. uberata and Mucor clavatus be demon- 

 strated if possible. We cannot be sure from an examination of 

 literature that the specimens on which these two species were 

 based were ever compared. The name Mucor clavatus was first 

 used by the younger Linne (29) in connection with the follow- 



12 Fries in connection with the description of C. uberata in Systema Myco- 

 logicum cites Lichen {Calicium) colpodes Acharius as a synonym. This is 

 evidently a mistake in citation since this species is given as Lichen (Imbri- 

 caria) colpodes by Acharius, and from the description clearly refers to another 

 organism. Fries apparently had in mind Lichen (Calicium) helopherus 

 Acharius which was collected at the Cape of Good Hope and is stated by 

 Acharius to be identical with Mucor clavatus Linnaeus. It is worthy of note, 

 however, that in the description of Corynelia uberata signed by Acharius in 

 Observationes Mycologicae the name Lichen helopherus is omitted from the 

 synonomy.
