more correctly referred it to Sow. figure t. 155, he did not change the 

 name, though there is no reason why Sowerby's original name Thele- 

 phora pannosa (or Stereum, it being a Stereum) should not be used, 

 surely none based on piiority. 



STEREUM THOZETII is known from three specimens at Kew fiom Aus- 

 tralia. Infundibuliform, entire, pale, smooth, even, with a short stalk. It grew in 

 earth. 



STEREUM BURTIANUM (Fig. 537). Mesopodial or pleuro- 

 podial. Pileus pale brown, infundibuliform, lobed or incised, uneven, 

 with radiating ridges. Sometimes spathulate, glabrous, with striate 

 margin. Stipe concolorous, smooth. Hymenium concolorous. Cys- 

 tidia, none. 



This species was named and figured in Peck's 57th Report. But 

 one collection of the American plant so named is known, which we 

 have seen in the museum at Albany. I have, however, a collection 

 from A. Yasuda, Japan, which, on comparison with my notes and 

 Peck's description, I think must be the same species. I find the same 

 plant also at Kew and Berlin from California under the (mss.) name 

 Stereum Harknessii, but I believe this was never published. 



Compare Stereum pallidum in Section 6. 



SYNONYMS, ETC. 



Thelephora Komobensis, Japan, Hennings, known from one collection in Japan, is Stereum 

 diaphanum, a rare species of the United States. Its occurrence in Japan is of interest. 



Stereum pannosum, England, Sowerby (as Helvella). The original name for Stereum Sowerbyi 

 as changed by Berkeley. This change was made through a mistake of reference as Berkeley afterwards 

 concluded, but he never changed back the name and we do not engage in that kind of work. 



Stereum riyulosum, Cuba, Berkeley. Only known from the type locality, two little specimens 

 each about the size of pin-heads. We do not know, but we do not doubt that they are Stereum undu- 

 latum. 



Stereum tenerrimum, Southern United States, Berkeley = Stereum undulatum. Also same in 

 Peck's records. 



Stereum Tuba, Ceyjon, Berkeley. This is not at all a Stereum, but a Cyphella which appears 

 quite common in Australian regions. We collected it in Samoa and it was named Cyphella grandis 

 (Myc. Notes, p. 258). Hennings also has a name for it, from Samoa. McGinty calls it Cyphella 

 Tuba (Berekeley) McGinty. 



Thelephora exigua, United States, Peck = Stereum undulatum. 



Thelephora Harknessii, "n. s." Harkness No. 475 in Phillip's herbarium, British Museum (also 

 at Berlin), is Stereum Burtianum. 



Thelephora liliputiana. South America, Montagne is Isaria (sic) nabelliformis. Peck, it seems, 

 was not the only one to discover that this was a "new species" of Thelephora (cfr. Thelephora rosella 

 below). 



Thelephora rosella, United States, Peck = Isaria nabelliformis. It is supposed to be a conidial 

 Pyrenomycete, but its ascous form is not known. There is, however, no basis whatever for referring 

 it as the conidial form of Xylaria corniformis as found in Ellis's Pyrenomycetes. (Cfr. Letter 43, 

 Note 44.) 



Thelephora Sullivantii, United States, Montagne = Stereum diaphanum, type at Paris. 



Thelephora Willeyi, United States, Peck = Stereum diaphanum.
