be told. There are also cotype remnants at Paris. I judge the plant is concrescens 

 or close. 



niveus, Java, Junghuhn. Type at Leidem is undeterminable, a white Poria, 

 or more probably the resupinate part of some Polyporus. 



niveus, Saccardo, Vol. 6, p. 118 is a lapsus for Polyporus nidulans which is 

 Polypotus rutilans. 



nivosellus, Cuba, Murrill = for me a thick specimen of Polyporus Calkinsii. 



Nonkahivensis, China, Patouillard. Based on two little frustules referred 

 recently to Polyporus lingua but not in the sense of Montagne I think. 



Xotarisii, Europe, Berkeley, nomen nudum. Not "described" and no specimen 

 found by me. 



obducens, British America, Berkeley. This is known from a single specimen 

 in Hooker's herbarium from British America about eighty years ago. It is thin 

 and reminds me of a piece of parchment paper. Recently it has been endorsed as 

 a "prior name" for Polyporus osseus. It is quite doubtful to me, and I should 

 not be disposed to disturb Polyporus osseus on such evidence. Fortunately, the 

 endorsement was made after Murrill's visit to Kew, or he would without doubt have 

 had a juggle for Polyporus osseus. 



oblinitus, Mauritius, Cooke = Polyporus bicolor. It is also = Polyporus san- 

 guinarius and the same collection. 



obockensis, Africa, Patouillard = Polyporus colossus. As for many years the 

 type of colossus in a jar at Upsala was unknown, the plant became fairly well known 

 under Patouillard's name. We would be in favor of continuing it, but we are not 

 partial to these latinized Ethiopian dialects. 



obvolutus, United States, Coo ke = Polyporus volvatus. 



ochraceo-cinereus, Europe, Britzelmayr. So little can be told from Britzel- 

 mayr's work that it is hardly worth listing the name. 



omalopilus, Cuba, Montagne (changed by Saccardo to homalopilus). It is 

 Polyporus gilvus. 



oroleucus, Java, Patouillard = Polyporus tropicus from same locality. 



ostreatus, Brazil, Leveille = Trametes cubensis. Type at Paris. 



pachycheiles, United States, Ellis. Probably equals cerifluus or crispellus. 

 These thin white species with reddish tendency are not all clear. It is not, how- 

 ever, semisupinus as stated, which has no reddish tendency. 



pachylus, British America, Cooke. A remnant, probably resupinate part of 

 Polystictus biformis. 



pachyotis, South America, Spegazzini. Only known to me from Rev. Rick's 

 determinations which are same for me as Polyporus Chaffangeoni. 



pallescens, Europe, Fries = Polyporus fumosus it is thought. Specimens I 

 have received from correspondents under this name are Polyporus fumosus. 



pallido-cervinus, United States, Schweinitz. The little frustule in Schweinitz's 

 herbarium is Polyporus rutilans. In the sense of Morgan it was Trametes malicola, 

 and in the sense of Berkeley (from Cuba) it was Polystictus biformis. 



pallido-micans, Europe, Britzelmayr. Another name only. 



Palmarum, Cuba, Murrill = Polyporus Calkinsii. 



paluster, United States, Berkeley. The type is a small specimen in very poor 

 condition and its identity not sure but I think it is Polyporus albellus which, 

 however, has no right to grow on pine. It has a thin but distinct crust. In sense 

 of Murrill Polyporus paluster is Polyporus albidus a plant with quite a different 

 surface. 



paradoxus, Europe, Fries. No specimen known. The description appears to 

 me same as Polyporus Soloniensis (cfr. Letter 42) which I am disposed to think 

 is a lapsus of Polyporus sulphureus. 



parvulus, Central America, Murrill. Based on two small specimens in Ellis' 

 herbarium which I would refer to subsessile Polyporus lucidus as Ellis did. 



pelleporus, Europe, Sowerby t. 230 = Polyporus fumosus. 



pellitus, Europe, Karsten. Unknown. Reads like Polyporus osseus. 



perplexus, United States, Peck. No specimen exists. Nothing known about 

 it excepting Peck thought at the time he named it, that it was different from the 

 common Polyporus cuticularis which he well knew at the time. Murrill who never 

 saw it, takes it as the name for Polyporus cuticularis which is rather far fetched 

 under these circumstances.
