 Chev, Par. t. 9./ 23. 



On very rotten wood, moss, &c., after much rain. Not uncommon. 

 '\Q"y beautiful just before maturity, and resembling a strawberry. 



Tribe 4. Trichodermace.e. (^g/g, a hair, and Iz^iLa, a 

 sMii). — Peridium composed of loosely interivovenflocci, rarely mem- 

 hrajious, evanescent in the centre. Sporidia conglomerate. Tex- 

 turejioccose. 



96. AsTERoPHORA. Ditm. Asteropliora. 



Peridium capitate, floccose above, evanescent. Sporidia an- 

 gular. — Name, a6rr,o, a star, and fggw, to bear. 



1. A. Agaricoides, Fr. (Agaric-shaped Asferophora) ; Lead 

 hemispherical furnished beneath with barren gills. Fr. Syst. 

 Myc. V. 3. p. 205. — Ast. Lycoperdoides, Ditm. in St. Deutsch, 

 Fl. t.26 . — Agaricus Lycoperdonoides, Bull. 1. 166. 516. f. I. Pers. 

 Sy7i. p. 325. 



On dry blackened Agarics of the Subgenus Galorrheus, as A. adus- 

 ius and A. pipcratus. Autumn. Occasionally in all parts of Great 

 Britain, but seldom abundant.— This curious plant so closely resembles 

 Agaricus parasiticus that it may easily be passed over as a state of it 

 corrupted by some parasite. The gills are however altogether spurious, 

 and the angular substellate sporidia under the microscope immediately 

 indicate the genus Asterophora. When young it has a light cottony 

 aspect, very different from the adpressed silkiness of the Agaric. The 

 latter I observe to spring from the inner substance of the matrix, the 

 former to be superficial, but 1 am not certain that this is constantly 

 the case. 



2. A. Lycoperdoides, Fr. {gill-less Asterophora) ; head hemi- 

 spherical even beneath. Fr. Syst. Myc. v. 3. p. 206 — Agaricus 

 Lycoperdonoides, Sow. t. 279. 



In the same situation as the last, llather more common.— I find the 

 stem frequently an inch long, as represented by Sowerby, and therefore 

 omit a part of^ Fries' specific character. The stem is sometimes quite 

 obsolete ; when present, silky, composed of fibres, white then greyish- 

 umber, solid, somewhat dilated upwards. Head hemispherical or some- 

 times globose ; peridium delicate, floccose, fugacious ; sporidia penta- 

 gonal or hexagonal, fawn-coloured. 



97. Onygena. Pers. Onygena. 



Peridium capitate, crustaceous, consisting of inter woven /?occ?, 

 evanescent. Sporidia rounded. Texture floccose. — Name, 

 oj/yj, a hoof, and yivoiiai, to spring from. 



1. O. equina, Pers. {horse-hoof Onygena) ; head lenticular 

 furfuraceous dirty- white at length more or less regularly splitting 

 all round, stem abbreviated. Pers. Syn. p. 203. 31oug. ^
