CLAVIS AGAKICINORUM. 213 



sent fibrous and fugacious ; pileus more or less campauiilate, margin 

 straight, at first adpressed to the stem ; stem cartilaginous, fistulose, 

 confluent with but heterogeneous from the hymenophorum ; gills ad- 

 nata, or with a decnrrent tooth exactly as in Mycena, Plate I. fig. 8. 

 Galera also corresponds with Nolanea, Plate II. fig. 17; PsaUiyra, 

 Plate IV. fig. 31 ; and Psathyrella, Plate V. fig. 34. The most typical 

 species is perhaps Agaricus sphagnorum, Pers., with broad gills and 

 decided sinus, but from its rarity I prefer to figure the common A. 

 tener, Schsefl'. — Hab. The greater number of species are terrestrial. 



The species are not numerous, and most are slender and brittle, 

 appearing in the autumn. The species figured is Agaricus (Galera) 

 teuer, Schasif. Spores -00034" x -0003". 



Subgenus 25. Tubakia, subgen. nov. sp. Naucoria,Y\-. (Plate III. 

 fig. 25). — Pileus generally depressed, at first with an incurved mar- 

 gin ; stem cartilaginous, hollow, confluent with but heterogeneous 

 from the hymenophorum ; gills decurrent. 



As in Eccilia, there are very few known representatives of this 

 position, either British or foreign, and the note appended to Omplialia 

 applies equally to Eccilia, Tubaria, and Beconica. As at present con- 

 stituted, some species of Omplialia are never depressed, but have a 

 pileus more or less hemispherical or even obscurely umbonate from the 

 first ; the same applies to Beconica. The analogous species of Ta- 

 baria falling to this place are given in the list. 



The species figured as a type is A. (Tubaria) furfuraceus, P. ; it is 

 strictly analogous, both in stnicture and habit, with Omphalia, Plate I. 

 fig. 9; Eccilia, Plate II. fig. 18; and Beconica, Plate IV. fig. 32. 

 Spores -0003" X -00016''. 



Series IV. Peatell^, Fr. Epicr. p. 212.— Spores various shades of Irownish- 

 purple, dark purple, or intense brown. 



Subgenus 26. Psalliota, Fr. Epicr. p. 212 (Plate IV. fig. 26). 

 — Spores dark brownish-purple, dark brown, reddish-purple, or pale 

 slate; veil universal, concrete with the cuticle of the pileus, and 

 fixed to the stem, forming a ring ; pileus fleshy ; stem distinct from 

 the hymenophorum, furnished with a ring ; giUs free, and rounded 

 behind, at first white, then pink, afterwards intense purple-brown. — 

 Hab. All are terrestrial, mostly growing in rich pastures and on ma- 

 nured ground.
