198 CLAVIS AGAKICINOUUM. 



stem ; but in Agarlciis (PholiotaJ fcrsns, Fr., it is so, aiitl tlic stem 

 is furnished with a fugitive riiio-, showing a clear analogy Ijctwcen 

 this species and Lepiota (Plate I.), Chamceota (Plate II. ), and Fsal- 

 llota (Phile IV.) ; neither are any brown-spored Agarics furnislicd 

 with a volva, unless, indeed, a trace of such a structure is indicated 

 in Cortiuarius (for CorlinariKs is certainly allied to Pkoliota and 

 Hebeloma), where many of the species have an adnate volva and 

 arachnoid ring. 



llemarks on Fries' new subgenus Inocyhe will be found under livhe- 

 loma. This latter subgenus resembles Gortinariiis in many respects, 

 even to the lesser groups, into which both are divided, depending on 

 the character of tlie pileus, whether it is slimy, moist, or squamulose. 



The subgenera Flammiila and Nancoria are in a most unsatisfactory 

 condition. They require thorough revision. The species oi Naucorin, 

 with decurrent gills and depressed pilei i^A. furfiiracens, P., etc.) I 

 remove to the next ]X)sition, as analogous in every respect to Omplial'm 

 and Ecc'dla, and describe under the name Tabarla. 



IV. PiiATELLiE, Parph-spored Agarics (Plate IV.). — Tlie affi- 

 nities and characters of all tlie subgenera are referred to under their re- 

 spective headings. I have already said that P'dosace is not Britisli. As 

 A. physaloiJes, Bull, has decurrent gills and a pileus at length de- 

 pressed, I remove it to the space corresponding amongst the Pratellce 

 to Oinplialia and Eccilia amongst the white- and pink-spored species ; 

 and name the subgenus Beconlca. 



V. Covvii'n kxiii, it Black-spored Agarics (Plate V.). — There is 

 little to be said about these in addition to the observations under the 

 respective subgenera. Psathyrella is very close to Coprinus, more so 

 than Panreoliis. In the Coprbiarli the unrepresented spaces are very 

 numerous. I am unable to offer any suggestion as to filling them, 

 unless by cutting up the genus Coprinus, the species of which genus 

 difler exceedingly in many points, especially in the attachment of the 

 gills to the stem. C. comalus, Fr., is clearly allied to Lepiota ; the 

 habit, scaly pileus, moveable ring, cliange of colour wlien cut, edible 

 qualities, etc., all point in this direction. The characters of some of 

 the otliers, as those growing on wood, etc., indicate other affinities ; 

 but till Agarics are better known these spaces must remain unoccupied.
