ADDITIONAL NOTES. 



Previous portions of this pamphlet were written at Kew, April, 1911. When 

 I reached home (October, 1911) I found it in type. Very little has been added 

 to my knowledge of this Section Ovinus. 



During the past summer I visited Rev. Bresadola, in the Dolomite Moun- 

 tains, of Tyrol. Rev. Bresadola I believe to have the best knowledge of Poly- 

 poroids in general of any one, but nothing developed in my conversations with 

 him to require any change from what I had previously written on the subject. 

 The following are a few additional notes that have come up since the previous 

 work was written. 



POLYPORUS CRISTATUS. Rev. Bresadola tells me that he sometimes 

 collects this species in Tyrol, not growing in beech woods as I suppose it occurs 

 in Europe, but in acerous woods. 



POLYPORUS CONFLUENS. I found this plant in the Tyrol Mountains. 

 There it is smaller, more confluent, and very little stem developed, and the 

 entire plant is much more abortive than it is in Sweden. This may be due, 

 however, to the season, as it was a very dry summer. I have never seen it in 

 Sweden excepting with well developed stems. 



POLYPORUS HARTMANNI. A specimen has since been received from 

 Miss Margaret Flockton, Australia. The spores are elongated, 5 x 12 mic., 

 hyaline, smooth. 



POLYPORUS MYLITTAE. Since the article was written I have found a 

 photograph of Polyporus Mylittae that was sent by Cooke to the British 

 Museum. It shows the abortive fructifications growing from the tuber. I have 

 never found a specimen of Polyporus Mylittae at Kew or its photograph, although 

 it is possible that they are preserved in the Economic Museum, where I did 

 not search for them. 



POLYPORUS TUBERASTER. As I have stated in the body of the 

 pamphlet, Polyporus tuberaster is said to be cultivated in Italy. The references 

 in literature that I have examined are mostly so old that I wrote to Prof. 

 Mattirolo, asking him if it was now produced. He has kindly replied in detail, 

 giving me the literature on the subject and the following note. The bibliography 

 was mostly quite ancient, the latest being dated about fifty years ago, so that 

 1 do not reproduce it. The following, however, is the information Prof. 

 Mattirolo gives me on the subject in regard to the use of the plant at the present 

 time : 



"As to Pietri or Polyporus tuberaster, plants are collected to this day in 

 the Campania, and I have an example obtained from the market in the vicinity 

 of Camerino. I have myself cultivated the sclerotia and obtained and eaten 

 some excellent Polyporus at Turin. Previously the sclerotia were in cultivation 

 much more frequent and were sold in the markets and villages of Southern Italy. 

 In Naples they are preserved in caves to obtain the edible Polyporus. The 

 sclerotia have gradually diminished in recent years, due to the clearing of the 

 forests."
