Lcpiotse preserved (and yet exposed to the air), that have retained their per- 

 fectly white colour for ten years or more. 



The subgenus Togaria, mentioned by Fries, fills up another blank space. 

 on plate 3 of my " Clavis ;" it occupies the middle position of the top three 

 spaces. It is again curious that the typical plant should not be British. 



Fries next refers to Hypholoma and its analogy with Entoloma and Flam- 

 mula, and says that the "Fasciculares" group of Entoloma is analogous with 

 Flammula ; this is undoubtedly true ; but Flammula is at present badly con- 

 tituted, and some of the plants have no affinity with each other. It follows, 

 therefore, that the following British species, viz., A. sullateritius, A. capnoides, 

 A. epixanthus, A. fascicuiaris, and A. disperses, instead of being placed at the 

 head of Hypholoma, as heretofore, by Fries, Berkeley, and others, must come 

 in at the end, and fill the blank position on plate 4, which is analogous with 

 Flammula on plate 3. 



Before leaving the Dermini and Pratelh-e, I will briefly touch upon your 

 reviewer's remarks on my subgenera, Tubaria and Deconica ; they are not, as he 

 states, founded upon the slight characters of decurrent gills, but decurrent gills 

 accompanied by other characters, as the depressed pileus and the nature of the 

 margin. The difficulty respecting such species as A. vulgaris, quoted by him as 

 being still left in Mycena and not removed to Omphalia, I have referred to 

 at p. 14, under the "Mycenariae" of Omphalia; the reference to A. camplophyUus 

 being left in Mycena, and not removed to Omphalia, is especially unfortunate, 

 as I have placed it in Omphalia, and not in Mycena. 



The Panzeoli are mentioned in conclusion by Fries as more analogous with 

 Naucoria and Psilocybe than with Hypholoma. The hollow stem and appen- 

 diculate veil, however, of A. fimiputris and its allies appears to me to bear a 

 manifest analogy with the " Appendiculati " group of Hypholoma. The sub- 

 genus Panseolus will on proper study probably bear subdivision. I am of 

 opinion that the colour of the spores is by no means a character of the first im- 

 portance amongst Agarics, and at page 3 of my work I clearly say that the alli- 

 ance of the species would be closer if the points of structure were followed. 

 Therefore I certainly do not consider the colour of the spores to be "all in all." 

 As to the genus Hygrophorus, that could not be cut up, as all the species have 

 white spores. I imagine Fries would not have founded the different sub- 

 genera of Agaricus on such a character as spore colour, if he had had such salient 

 points of distinction as we find in Lactarius and Bussula under "Piperates," 

 "Dapetes," " Limacini," "Kigidse," " Fragiles," &c. As to the "trama" in 

 the gills of Agarics, and its value as a character, the subject still wants 

 working up. Fries, however, is clearly right in asserting its absence in Paxillus 

 involutus, and Nylander and Hoffmann are mistaken. 



The first plate shows at a glance any modification of the arrangement 

 of Agarics with white spores. Those with coloured spores are analogous. It 

 differs from that of Fries in the removal of Pleurotus from the bottom right- 

 hand corner position to the one above it ; and in the transposition of Om.
