lard. The genus with its peculiar spiny, stellate hyphae tissue corresponds to Asterostroma 

 in the Thelaphoraceae. The genus Hydnochaete, to which Peck referred the plant, if it is 

 maintained, is cogeneric with our common Irpex cinnamomeus, being simply a Hydnaceous 

 plant with setae on the hymenium, the "Hydnoporia" of Murrill's delayed discovery. 



Asterodon ferruginosum is not a synonym for the more common Hydnum ferruginosum 

 of Europe and United States, which has tubercular colored spores, and is now called Calde- 

 siella. The original specimen was found mixed in a collection of Hydnum ferruginosum, and 

 it is confusing and unfortunate that the same specific name was adopted. 



NOTE 203. Hydnum strigosum, received trom Dr. C. H. Kauffman, from Michigan. A 

 very rare plant and this is the first specimen I have received from an American corre- 

 spondent. I collected it once in Michigan. This is the plant with which Banker made the 

 most comical bull that was ever made in American mycology. He identified it with a mis- 

 labeled specimen of Polyporus hispidus in Schwcinitz' herbarium and wrote a page article 

 in his "Revision of Hydnaceae" (sic) based on a Polyporus (sic). Then, when he found the 

 specimen which both Peck and Ellis had correctly determined as being Hydnum strigosum, 

 Banker discovered that it was a "new genus" (sic) and a "new species" (sic). 



Hydnum strigosum is as variable as it is rare. This specimen from Dr. Kauffman is 

 dimidiate with stratose flesh a cm. thick. Those I collected were stipitate, with very thin 

 flesh. In addition it has also been found resupinate, and named Hydnum stratosum by 

 Berkeley. Notwithstanding its variations there is no mistaking it. It has a "structure" 

 peculiar. The alternate stratae are composed of compact and loose brown hyphae, the latter 

 loosely woven into coarse bundles. The spores are subglobose, 4 mic. smooth, transparent, 

 guttulate. 



Hydnum strigosus is both rare and boreal in both America and Europe. With us it is 

 known from Michigan, New York, Nebraska, Iowa, Indiana, and Ohio, but always rare. In 

 Europe it is only known from Swedish specimens, and northern Sweden at that. 



NOTE 204. Polyporus glomeratus, received from Dr. C. H. Kauffman, from Michigan. 

 The first specimen I have ever gotten and of much interest to me. This species has been 

 confused by Murrill and myself with Polyporus radiatus, which it resembles in general ap- 

 pearance. There is a small cotype specimen at Kew, and in studying it last winter I made 

 the discovery that its structure, which is exceptional among the polypores, was entirely dif- 

 ferent. Imbedded in the tissue of the pores are large, thick, deeply colored, long, cylindrical 

 bodies. Similar bodies are found in the tissue of several foreign species, Fomes pachyphlaeus 

 of the East, Polyporus Rickii of the American tropics, but we have in the United States, as 

 far as known, no other species with this character. 



The specimen was sent as a Fomes, and the layers are quite evident, but I think it is 

 better classed as a Polyporus, for it is apparently an annual, the old layers being dead, and 

 the new growth forming over them, but distinct, and not continuous. In its texture it is 

 the same as such annual species, as Polyporus radiatus. 



A small fragment such as I have heretofore seen closely resembles Polyporus radiatus, 

 but not this specimen. It grew on Acer encrusting logs for several feet and resupinate, also 

 pileate on stumps. The fresh pores are greenish yellow, the old pores brown. Setae none 

 found on the hymenium. Spores subglobose, 5-6 mic., very pale color, transparent, guttulate. 

 Polyporus glomeratus was named over forty years ago, and we have just gotten a clear idea 

 of it. It is very close to Polyporus Rickii of the American tropics, which may be a conidial 

 bearing form of same thing. 



NOTE 205. Polyporus (Amaurodermus) Torrendii. Pileus orbicular, reniform, about 

 3 cm. in diameter, dark reddish brown, darker when old, the edges when young chestnut red. 

 Stipe lateral, 6 cm. long. 3-4 mm. thick, with dull reddish brown velutinate surface. Pores 

 large, 1-2 to mm. long, (1 cm.) almost reaching the crust. Spores smooth, colored, varying 

 globose 12 x 12, to subglobose, 12 x 14, some 10 x 14 mic. 



This is a unique species, which should be included in Section 5, Amaurodermus, of our 

 Stipitate Polyporoids. It differs from all species heretofore known with smooth spores in its 

 large pores. It is quite close to Polyporus insularis of New Caledonia, which has rough 

 spores. The type specimens were received from Rev. C. Torrend, Bahia, Brazil. 



NOTE 205. Hypolyssus clavarioides, from Rev. C. Torrend, Bahia, Brazil, and named 

 Telephone clavarioides by him. A unique and novel thing, but I would put it with Hypolyssus 

 rather than to multiply the genera. I presume Telephone is a new genus. It is something 

 out of the ordinary, at any rate. I believe it has not yet been published. 



NOTE 207. Polyporus mutabilis, from Rev. C. Torrend, Bahia, Brazil. Sent as sub- 

 hydrophilus, Speg. I do not know the latter, biit if so, surely a synonym for Polyporus muta- 

 bilis, which is common in our southern United States. 



NOTE 208. Polyporus pseudofruticum. Pileus dimidiate, ungulate. Context dual, the 

 old hard and ligneous, the young soft and spongy. Surface soft. Color of old context cinna- 

 mon brown, of the new growth, yellow ocher. Setae none. Spores 2V. x 3Vi hyaline, smooth. 



The old context is harder, but the young is same spongy nature as Polyporus fruticum. 

 Were it not for the hyaline spores, it would be referred to fruticum. This is probably a better 

 Fomes, and so is Polyporus fruticum at times. Notwithstanding the discrepancies of spore 

 colors, I think better classed as a form of Polyporus fruticum. Specimen from Rev. C. Tor- 

 ren, Bahia, Brazil.
