is. Prof. Burt would change the name on the strength of a scant 

 specimen found in Schweinitz' herbarium, but as I look at it, that is 

 basing nomenclature on accident rather than facts. Schweinitz' 

 herbarium does not always represent Schweinitz' views as proven in 

 a number of cases. 



The genus Septobasidium is common, particularly in the tropics. 

 It always occurs on living branches and is not saprophytic nor is it 

 parasitic on the wood. It has been known for many years that there 

 is some connection between species of this genus and scale insects. 

 In fact it was mentioned by Fries, and Fetch has recently stated that 

 the earlier stages are parasitic on colonies of scale insects (Cfr. Note 

 42). The genus Septobasidium was named from the peculiar shape of 

 the spore bearing organs, which are similar to those found in some of 

 the tremellaceous genera. As a matter of fact, however, we feel 

 confident as to a great many species of Septobasidium, of which we 

 know nothing whatever about the basidia. Museum specimens are 

 rarely fertile, and when they are it is a most difficult, microscopic 

 problem to find the basidia. The tropical species of Septobasidium 

 have never been separated. They are found in our literature, usually 

 as Thelephora, but also as Daedalea, Hymenochaete, Hydnum, 

 Corticum, Helicobasidium, etc. 



I have a list of forty-six supposed species that I found in about 

 a half dozen different genera in the museums of Europe, which, I 

 venture, from their habits and appearance will eventually be classed 

 in Septobasidium. We have in the United States two very similar 

 species named Septobasidium pedicellatum and Septobasidium 

 castaneum, which differ chiefly in color. Our common species is 

 pedicellatum. Castaneum, which is a darker species, is of a more 

 southern range. On comparison, Mr. Bijl's specimens are closer in 

 color to pedicellatum than castaneum, but as a rule I think the speci- 

 mens that I noted abundantly in the museums and which were by 

 Berkeley referred to Thelephora pedicellata, mostly approximate 

 Septobasidium castaneum in color. I think it will prove eventually 

 that Septobasidium castaneum is the most common species of the 

 tropics. 



The following plants that I have (mostly) noted in the museums will finally, 

 I believe, be classed as Septobasidium: 



Septobasidium albidum, So. Amer., Patouillard, as Septobasidium. 

 abnormale, Brazil, Hennings, as Corticium. 

 atratum, West Indies, Patouillard, as Septobasidium. 

 Bagliettoanum, Fries, Europe, as Hypochnus. 

 bogoriense, Java, Patouillard, as Septobasidium. 

 capnodes, Ceylon, Berkeley, as Thelephora. 

 Cavarae, Europe, Bresadola, as Septobasidium. 

 Carestianum, Europe, Bresadola, as Septobasidium. 

 cinchonae, Java, Raciborski, as Septobasidium. 

 coffeicola, Africa, Hennings, as Septobasidium. 

 crinitum, Brazil, Fries, as Thelephora. 

 dictyodes, Ceylon, Berkeley, as Thelephora. 

 fisso-lobatum, Brazil, Hennings, as Hymenochaete. 

 frustulosum, Cuba, Berkeley, as Hymenochaete. 

 Henningsii, Java, Patouillard, as Septobasidium. 

 humilis, Java, Raciborski, as Septobasidium.
