LETTER No. 37. 



BY C. G. LLOYD, CINCINNATI, JUNE, 1911. 

 THE POLYPOROID TYPES OF JUNGHUHN PRESERVED AT LEIDEN. 



Junghuhn was among the first to name foreign species of fungi. 

 He made large collections in Java and published a paper that was finely 

 illustrated, in 1839. If all of his types were destroyed many of bii 

 cies would still live, for he gave good accounts of them and good figures 

 of many of them. All of the figures that he 'cites were not published 

 as it was his intention to continue the work, and he numbered his 

 paper "Fasc. i ," but no further papers were issued by him on the sub- 

 ject. Dr. Goethart assures me that the originals of Junghuhn's figures 

 are not preserved in the museum at Leiden. 



However, there are at Leiden colored drawings of a large munl>er 

 of Javanese fungi, and they are the best I have ever seen of tropical 

 fungi. The name of the author of these icones has been lost, but I 

 think I have found evidence to trace them to Zippelius. Most of them 

 are named as new species and it was evidently the intention to publish 

 them, and it is unfortunate that they were not published as they were 

 mostly "new species" at that time. Many of them have been named 

 since. I hope to have more to say as to these icones in a future letter. 



Junghuhn's specimens are mostly preserved, and of the thirty- 

 three species that he named I found the types of twenty-seven. The 

 remaining six have probably been misplaced in covers where they do 

 not belong, or his labels for the specimens have been lost. Tli- 

 no trouble in identifying Junghuhn's types for he labeled each in his 

 peculiar writing. 



For many years under the old directors the mycological specimens 

 were neglected in the museum at Leiden, and many specimens were 

 loose in drawers or put away in packages. When I first visited the 

 museum it was not possible to work with any excepting those that 

 were in the herbarium covers. A few years ago Dr. Jongmans had 

 the loose specimens all placed in boxes and numbered and the number 

 that I cite refers to these boxes. 



When Junghuhn wrote on fungi several of the Polyporoid genera 

 had not acquired Definite me;inii|gOfi(t;j|BIPOJHftW s occurrence per-
