USSHER, C. B., Java: 



Ptychogaster ? Fomes (Ganodermus?). Polystictus dermatoides. 



VAN BAMBEKE, CH., Belgium (y) : 



Hydnum erinaceum. Daedalea gibbosa. Polystictus fumosus. Poly- 

 porus borealis. 



Polyporus (Ganodermus) Oerstedii. This plant is same as Polyporus 

 lucidus except that it has no stipe. It is often held to be a form of lucidus. 

 I think it is entirely distinct, biologically, and that lucidus always has a stipe 

 at least in Europe. This sessile plant has various names (resinaceus in 

 Europe, sessile in America, etc.), but the first was Polyporus Oerstedii as 

 named by Fries from the West Indies. 



VANDERYST, HYAC., CONGO, Beige (z): 



Polystictus xanthopus. Polystictus florideus (which is only a dark form 

 of xanthopus). Polystictus (sp. unknown to me). Polystictus Drybowski 

 (not Hexagona as in my synopsis). Hexagona discopoda. Hexagona der- 

 matiphora. Trametes cingulatus. Polystictus lanatus. Polystictus flavus. 

 Polystictus sanguineus. 



Polyporus licnoides (?). One specimen is thin and typically marked as 

 licnoides (type), others are more thick (1 cm.) than licnoides should be to 

 be normal. 



Polyporus (Amaurodermus) salebrosus. Pileus strongly rugulose sul- 

 cate, brown, with a dull (not laccate or velutinate ) surf ace. Context very 

 thin, brown. Pores minute, with brown context and concolorous mouths 3 

 mm. long. Spores very faintly colored, globose, smooth, 10-12 mic. Stipe meso- 

 podial, brown, smooth, but dull surface, % x 6 cm. This species belongs to 

 Section 5 (Amaurodermus) of recent Stipitate Polyporoids. It differs from 

 Polyporus rugosus, which is its nearest ally, in its very thin context, very 

 minute pores, and jts very pale-colored (almost subhyaline) spores. The 

 context is so thin it might be sought in the Polystictus section, but brittle 

 (not flexible), hence I think best placed in the Polyporus section. The pores 

 are minute, hardly visible to the naked eye. 



Hexagona Pobeguini. The velatinate pore surface under the microscope 

 resolves into brown setae, but with the appearance of being projecting 

 hyphae and not the surface setae of the Hymenochaete type. Many of these 

 are collected into bunches visible to the naked eye, and the same nature as 

 those of the "genus" "veluticeps," I judge. 



Polyporus Oerstedii. Polyporus (unknown to me). 



WILLIAMSON, H. B., Australia: 



Hexagona Gunnii. These are the first specimens I have gotten of this 

 characteristic Australian species (cfr. Syn. Hexagona, p. 15). 



Polyporus ochroleucus. The finest and largest specimen I ever saw of 

 the species. 



Fomes robusta (Cfr. Note 14, Letter 33). Stereum hirsutum. Poly- 

 stictus sanguineus. Schizophyllum commune. Stereum. Unknown to me. 

 Probably lugubris (from its name), which I do not know. 



WOULFF, E., Russia: 



Trametes pini. Daedalea quercina. Fomes pomaceus. Polyporus sul- 

 phureus (old, discolored). Phlebia radiata.
