pores are completely filled with white hyphae, but I doubt if that is a normal 

 feature of the plant. Setae, none. Spores globose, colored, 5 mic. While the inter- 

 posed layers of context are unusual among Fomes, species based on this feature in 

 Europe (Fomes vegetus) are known to be abnormal conditions, and that may be 

 the case in this instance. On the other hand, Fomes connatus is always so charac- 

 terized. 



griphaeformis, Australia, Berkeley. No type exists. 



Haematoxyli, Jamaica, Murrill. Based on one collection which, except as to 

 shape (more applanate), is quite close to Fomes igniarius and probably a form. 

 The context is dark brown. The "honey-yellow-context" of the description was a 

 careless observation of some yellow, mycelial growth that had overrun the surface 

 of some of the old tissue. 



halconensis, Philippines, Bresadola (as variety of spadiceus). Unknown to 

 me. It seems quite large to be referred as a variety of spadiceus. 



Hasskarlii, Java, Leveille. The type cited at Leiden is the same as senex of 

 this pamphlet. Cotype at Kew is Fomes pectinatus. Owing to the confusion, we 

 prefer to use Montagne's previous name, Fomes senex, although that was also 

 badly confused by Montagne. We have heretofore used the name Hasskarlii (cfr. 

 Letter 38). 



helveolus, Europe, Rostkovius. The figure seems to be Fomes pinicola, but the 

 description does not at all accord. Fries so referred a plant collected by Lindblad, 

 which Romell thinks must have been Fomes pinicola. Rostkovius described helve- 

 olus as being "fleshy," but no similar fleshy plant is now known in Europe. 



hippopus, Incog, Bresadola, = Fomes hornodermus. This is based on an old 

 specimen in Willdenow's herbarium, labeled "Boletus Hippopus," but not pub- 

 lished until 1890. Spores teste author 5x8-9. In Saccardo (9. 174) it is in error 

 ascribed to Europe. It corresponds to the common plant in Africa, which was 

 probably its source. The African form has a smoother, more even surface than the 

 American, and might be maintained as a form. 



Hohnelii, Java, Bresadola. Unknown to me. Compared to Fomes zelan- 

 dicus, with setae and colored spores, 5x6. 



holomelanus, Brazil, Cooke, = Fomes atro-umbrinus. Berkeley labeled two 

 lots, one atro-umbrinus (which he published), the other holomelanus, which Cooke 

 dug up and published. They are exactly the same thing, same collector, and prob- 

 ably same collection, v. Hohnel has an interesting notation on the type of holo- 

 melanus that it is a Ganodermus (sic). 



hyperboreus, Canada, Berkeley. No type exists. Guessed by Murrill to 

 have been possibly Fomes igniarius, which appears to have been a bad guess if its 

 context was "pale cervine," as described. 



hypopolius, Australia, Kalchbrenner (as Polyporus). No specimen in museum, 

 but description indicates Fomes annosus. 



ignarioides, Mexico, Patouillard, = for me young Fomes rimosus, same context 

 color, spores and absence of setae. The surface is not rimose, but the specimen is 

 young. If this is not Fomes rimosus it is surely Fomes endotheius, which is too 

 close to Fomes rimosus. The context color (whence the name) is not that of Fomes 

 igniarius, but Fomes robustus, the latter being misknown as Fomes igniarius locally 

 in France. 



inaequalis, Finland, Karsten (as Trametes). Specimen at Upsala appears to 

 me to be young nodules of Fomes igniarius (malvenu). 



incanus, Europe, Quelet. Quelet claims that Fomes ulmarius, fraxineus, and 

 cytisinus were all the same species for which he invented a new name, Fomes incanus. 

 If it were true, which it is not, there would be no occasion for a new name. 



incrassatus, Australia, Berkeley, = Fomes leucophaeus. 



introstuppeus, Perak, Cooke, = Fomes fomentarius. 



Inzengae, Italy, De Notaris. This is the common Fomes fomentarius. Several 

 exsiccatae specimens are found in the museums. 



irregularis, United States, Underwood (as Polyporus), = Teste Murrill, sub- 

 resupinate Fomes annosus. I never took the trouble to look it up. If Underwood 

 did not know the common Fomes annosus, he was particularly competent to an- 

 nounce "new species." 



Kamphoveneri, Tahiti, Fries, = Fomes lignosus. Type at Upsala. At one 

 time this was the name used by Bresadola, though he has since accepted my cor-
