Pileate and Clavate Tribes of Hymenomycetous Fungi. 93 



the spores appears to be uniformly binary, the one being ex- 

 actly opposite to the other. The other pair appears to be sup- 

 pressed. 



The arrangement is quaternary again in 



Ag. nebularis, Batsch. 



— grammopodius, Bull. 



— ceraceus, Wulf. 



Ag.pelianthinus, Fr. 

 — balaninus. Berk. 



In the two latter, which belong to the section Calodontes, 

 besides the fertile sporophores, there are barren ones or utri- 

 cles, which are coloured, and give the peculiar character to 

 the section. 



Ag. radicatus, Relh. Ag.pudens, Pers. 



The gills are studded with cells much longer than the spo- 

 rophores, which in some states are surmounted by a large pel- 

 lucid globule. This at length vanishes and leaves the tip of 

 the utricle denticulate. 



Ag. velutipes, Curt. 



— peronatus, Bolt. 



— oreades, Bolt. 



— tenacellus, Pers. The gills have 



utricles like those of Ag. radi- 

 catus. 



— Rotala, Scop. 



— ostreatus, Jacq. 



Ag.prunulus, Scop. 



— fertilis /3. intybaceus, Fr. Occa- 



sionally in this species there 

 appear to be only three spiculse 

 and three spores. 



— rhodopolius, Fr. 



chalybt 



Pers. 



— asprellus, Fr.. or an allied species. 



In most of the HyporrJiodia the spores are very irregular in 



form, with a globose central nucleus (sporidium) which is 



small in proportion to the spore itself. 



Ag.ge?itilis, Fr. 



— scaurus, Fr. In this species there 

 are sometimes five spores to- 

 gether. 



— rimosus, Bull. 



— cucumis, Pers. 



— tener, Schaeff. 



trechisporus, Berk. The spores 

 have little granules upon them. 

 The utricles are like those of 

 Ag. pudens. 



involutus, Batsch. Gills with 

 large pointed transparent utri- 

 cles many times longer than 

 the sporophores. 



Ag.pusillus, Dec. Cylindrical utricles. 

 Spores occasionally reduced to 

 two. 



campestris, Linn. 



— lateritius, SchaefF. 



— stipatus, Pers. 



— gracilis, Fr. 



— semiovalus, Sow. 



— titubans, Bull. 



— disseminatus, Pers. 



{Gomphus) rutilus, 

 Spores elongated ; 



SchaefF. 

 grumous, 



contents disposed in two masses.
