 collections of this from Japan from Prof. Yasuda. It was named and figured Tfew yea

NOTE 92 Stereum affine. I have received from Dr. G. B. Zenker, Africa, a nice 

 collection of this common tropical species. While it is common in the tropics, it is usually 

 in museums misreferred to Stereum elegans. Dr. Zenker's collection is said to be a "type" 

 of Thelephora Amigenatska, discovered by Hennings. Though there is no specimen in the 

 cover at Berlin, I presume from the description this is correct. Dr. Hennings evidently 

 named it for Dr. Zenker, however, as being "Thelephora cfr. aurantiaca Berk.," as 

 specimens so named are found in various museums. As Berkeley never named any speci- 

 men "ThelepTiora aurantiaca," it would be quite difficult to make the comparison as 

 requested. 



NOTE 93. Cladodcrris Floridanus. Usually growing on top of log, and then cup 

 shaped with short stipe. When on the side of log flabelliform or orbicular, reduced to a 

 short stipe-like attachment at the base. Upper surface reddish brown, zoned, with ap- 

 pressed, compact, thin, tomentose pad near base. Hymenial surface reddish brown, densely 

 minutely papillate, disposed in narrow ridges, put not with the branching, strong veins 

 of other species of Cladoderris. Cystidia none. Spores compressed globose 2 Yz x 3 

 hyaline, smooth, with a small gutta near the end. 



Growing on frondose wood and quite rare at Bayard, Florida. 



As only recently I hunted up all the species of Cladoderris in the museums of Europe, 

 and expressed the opinion that but one valid species had been named in the last sixty 

 years, I was a little surprised to find one growing in Florida. 



NOTE 94. An English tradition corrected. Cordyceps gracilis not Cordyceps en- 

 tomorrhiza. For more than a hundred years the English mycologists have been recording 

 as their most frequent species, Cordyceps entomorrhiza, which was originally named from 

 England. I presume I have seen not less than fifty different collections in the London 

 museums labeled "Cordyceps entomorrhiza Dickson," and in the entire lot not one that 

 is correctly named. In fact, Cordyceps entomorrhiza seems to be a very rare species in 

 Europe and I have never seen an English specimen. It was one of the first Cordyceps 

 to be named from England by Dickson, in 1785, in his "Plantarum Cryptogamarum Brit- 

 tanniae, " and he gave a characteristic and unmistakable figure of it. It is a slender 

 species with a globose head. The perithec : i ;ire protruding so that the head is rough, 

 resembling to no small degree the fruit of a Banunculus. About forty years later Greville 

 illustrated and named Cordyceps gracilis. It is a more obese species than Cordyceps 

 entomorrhiza and the perithecia are include 1 so that it is perfectly smooth and even. 

 There is little resemblance between it and Cordyceps entomorrhiza and the two species 

 should never have been confused. 



Cordyceps gracilis is common in Britain, and the error got started that gracilis was 

 a synonym for entomorrhiza and has been copied and handed down through all the 

 English mycological books. How the error originated it is hard at this late date to 

 explain, but when Berkeley first met Cordyceps gracilis, a single specimen, he referred 

 it to Dickson's figure, but he noted the difference and commented on it, but thought 

 evidently it was probably due to variation of a single specimen. Afterwards when speci- 

 mens became more common with him he forgot the difference apparently. Tulasne in his 

 classical work on the genus took the name Cordyceps entomorrhiza from British source 

 (specimen from Broome) and renamed Dickson 's plant Cordyceps cinerea. It is hardly 

 possible that Tulasne ever saw the original figure of Dickson, for Tulasne was too keen 

 and critical an observer to mistake Dickson's figure, or to confuse two species that have 

 so little resemblance to each other as these two have. No one has ever presumed even 

 in England to go behind Tulasne, and thus it became the common custom to call Cordyceps 

 gracilis by Dickson's name Cordyceps entomorrhiza. In this account I have only used 

 the generic name Cordyceps, although the earlier writers called it Sphaeria and Tulasne 

 called it Torrubia. These unimportant features have no bearing on the error. 



Cordyceps entomorrhiza as far as I have learned has never been found in England 

 since Dickson collected and figured it in 1785. Cordyceps gracilis is common and many 

 collections have been made. By what strange chance Dickson happened to find this 

 rare species and not the more common one is hard to explain, but it led to an error that 

 has persisted now more than a hundred years. Whether it is feasible now to correct
