Russian specimen sent by Mr. Woulff agrees exactly with the original plant 

 from England. Another species, Battarrea Stevensii, is based on an old 

 figure by Pallas from Russia. While it is much larger and more robust 

 than the English plant, it is well established that it is only a large form 

 of it. Polyporus Schweinitzii. Polyporus hispidus. Polystictus versicolor. 

 Polyporus adustus. 



Genus unnamed (I believe). A gasteromycete closely related to Seco- 

 tium. The spores are globose, 4 mic. There are no permanent cells or 

 columella as in the genus Secotium, but remnants of the trama plates 

 remain. It has no capillitium. Polystictus hirsutum, var. lutescens. 

 Panus rudis. Fomes fomentarius. Polyporus mollis (=P. Weinmanni). 

 Calvatia saccata? Fomes roburneus? (See Note 58). 



YASUDA, PROF. A., Japan: 



Polyporus Yasudai (See Note 59). Hydnum nigrum. Craterellus 

 cornucopiodes. Irpex lacteus. Calvatia lilacina. Polysaccum pisocarpium. 

 Polyporus confluens. Trametes Bulliardii. Scrupose form (Sp. See Note 

 55). Septobasidium (Sp.) (cfr. Note 42, Letter 43). Polyporus Cumingii. 

 Polystictus. Species not recognized by me. Calvatia Gardneri. 



Also several Clavarias which I do not know as to species. 



NOTE 45. Calvatia defodiodis. Peridium oblong, white, smooth, with a short, 

 rooting base. Sterile base none. Gleba pale olive. Capillitium very scanty, of cob- 

 webby threads, hyaline, branched, flaccid, 5 mic. in diameter. Spores pale colored, 

 subhyaline, smooth, mostly globose, 4-5 mic., some oval and some piriforni. 



This is a most curious little puff ball found by Simon Davis, on a high altitude 

 at Meeteetse, Wyoming. It measures about 2-3 cm. high by a cm. thick. It grew 

 imbedded in the (evidently sandy) soil with only the tip projecting, and Mr. Davis 

 writes me "was very difficult to find, owing to its strong resemblance in shape and 

 color to a small, white stone." It is an anomalous species in the genus Calvatia, 

 nothing in fact very similar, and might be considered as a new genus. It differs from 

 all other species not only in its habits and small size, but in its absence of sterile 

 base and very scanty capillitium. Its dehiscense is unknown to me, though I think 

 the peridium evidently breaks up in the manner of a Calvatia. 



NOTE 46. Podaxon Fartowii. From L. C. C. Krieger, California. Collected by 

 G. P. Rixford, Topeck, Arizona. Two collections quite different in general appearances, 

 due to age and development, but both the same species, which is the only one known in 

 the United States. S. B. Parish, who has recently explored the eastern part of the 

 Colorado desert, writes me that "Podaxon Farlowii is by no means rare throughout 

 the region, growing in depressions in clay or loamy soil, where for any reason a little 

 water has stood and evaporated. In such a place one can almost comnt upon finding it." 



NOTE 47. Polyporus corrnscans. Received from L. C. C. Krieger, Chico. Cal., and 

 O. M. Oleson, Iowa. A rare plant and one that is imperfectly known in our "literature." 

 When young, it is soft and "fulvous," and in this condition was well described by 

 Fries as Polyporus corruscans. I found it at Upsala on his favorite collecting grounds, ' 

 agreeing exactly with his description. When old it becomes indurated and context more 

 red (such as specimen recently received from L. C. C. Krieger. Chico, Cal.). There is 

 a drawing in Fries' collection, which Fries made from a specimen he found at Salmy- 

 body, near Upsala, and labeled in his own writing, "Polyporus fulvus." not recognizing 

 it as the old condition of his own Polyporus corruscans. Bresadola has recently based 

 a "new species" Polyporus Friesii on this. 



This is not the drawing, however, that was reproduced (posthumously i in Fries' 

 Icones T. 184, as Polyporus fulvus. The latter drawing was made by Linguist at 

 Femsjo, and may and may not represent the plant. If it does, it is very inaccurate. 



Polyporus corruscans is very imperfectly known both in Europe and America. In 

 this country it has been called Polyporus dryophilus. In Europe I have collected it at 

 Berlin and have specimens from near Paris, but Polyporus corruscans does not figure 

 in either French or German records as far as I have noted. 



NOTE 48. Exidiopsis alba. We have a very common, tremelliueous plant occurring 

 in the United States that is pure white and which has been known in all of our litera-
