ing description : " clavatus. Mucor perennis, stipite filiformi 

 nigro, capitulo obtuso nigro glabro. Habitat in foliis Arborum. 

 Refert puncta in frondibus Filicum." He fails to state where he 

 obtained his material and the description certainly cannot be re- 

 garded as applying unquestionably to C. uberata. The identity 

 of the two forms could be demonstrated, therefore, only by a 

 comparison of the type materials. An authentic sypecimen of 

 Mucor calvatus probably does not exist. The herbarium of 

 Linnaeus and that of Sir J. E. Smith with which many of the 

 younger Linne's specimens are incorporated have been examined 

 for the writer by Miss E. M. Wakefield. She states that the 

 only specimen in the herbarium bearing the name Mucor clavatus 

 is labeled in an unknown handwriting, is on bark, not leaves, and 

 is not a Corynelia at all, but Calosphaeria prince ps as noted on the 

 sheet by Berkeley and Massee. Moreover although Acharius, 

 Persoon, and Fries cite Mucor clavatus in their publications an 

 authentic specimen of this species is not present in any of their 

 herbaria today. 



A specimen of recently collected material from South Africa 

 communicated by Miss Doidge was mailed to Professor O. Juel, 

 curator of the herbarium of Elias Fries, with the request that he 

 • compare it with the original material of Corynelia uberata de- 

 posited at Upsala. He has supplied the following facts. A 

 single specimen in the herbarium bears a label written by Fries 

 as follows: "Corynelia uberata Fr. Cap. B. sp. Dedit Acharius, 

 Exiguum, at characterist." It consists of a fragment of a leaf 

 bearing two stromata, only one of which is well developed. 

 Most of the perithecia have been broken away, only one or two 

 being in good condition. These are, however, of the same shape 

 and size as those on the specimen from Miss Doidge submitted 

 for comparison. Since this specimen in the herbarium of Fries 

 was received from Acharius and since it is the only specimen in 

 the herbarium labeled by Fries as Corynelia uberata, we are justi- 

 fied in believing that it constitutes a portion of the type material 

 of this species. Moreover in the herbarium of Thunberg at 

 Upsala there is another specimen, also fragmentary, which bears 

 the same data as the specimen of Fries and agrees with it in
