11. A. (Pleurotus) fadfer, n. s. Csespitosus, phosphoreus, 

 fusco-flavus; pileo tenui convexo subumbilicato ; stipite sub- 

 centrali solido fibrose albido-pruinoso ; lamellis angustis com- 

 positis decurrentibus. Curt. no. 3503. Pennsylvania, Dr. Mi- 

 chener. 



Csespitose, phosphorescent, brownish-yellow. Pileus 3 inches 

 across, thin, convex, at length expanded, slightly umbilicate. 

 Stem 5 inches or more high, ^ of an inch thick, subexcentric, 

 fibrous, slightly pniinose. Gills narrow, compound, decurrent. 

 Spores white. 



A highly curious species with the habit of A. illudens. 



12. A. (Naucoria) argilhsus, n. s. Pileo firmo convexo pal- 

 lide fusco-luteo ; stipite cavo deorsura attenuate albo ; lamellis 

 angustis adnexis ex albo argillaceis. Curt. no. 2908. On earth 

 in woods, Oct., South Carolina, H. W. Raven el, Esq. 



Pileus 2-3 inches across, convex, subcoriaceous when dry, 

 smooth, firm, of a light brownish yellow. Stem 4 inches high, 

 \ inch thick, firm, cartilaginous, white, hollow, rooting, attenuated 

 downwards. Veil none. Gills white, very numerous, narrow, 

 slightly attached, at length discoloured from the very copious pale 

 argillaceous, elliptic, subcymbiform, rather minute spores. 



Agreeing with A. Cucumis in the inflected margin. The colour 

 of the spores is purely argillaceous. We cannot point out however 

 any species closely allied. The general appearance is that of A. 

 carnosus. The spores are most copious, and when moistened 

 feel very glutinous. 



13. A. (Naucoria) Curcuma, n. s. Pileo hemispherico fusco- 

 luteo, e floccis fasciculatis brevibus frequentissime squamuloso ; 

 came lutea ; stipite solido fusco fibrilloso ; lamellis ventricosis 

 emarginatis subadnatis ferrugineo-ochraceis. Curt. no. 2913. 

 On an old stump, Nov., South Carolina, H. W. Eavenel, Esq. 



Pileus f inch across, hemispherical, dark brownish-yellow, 

 densely covered with squamose fascicles of flocci. Flesh thin, 

 yellow. Stem brown, 1-liinch high, f line thick, solid, fibril- 

 lose, but not scaly, dilated at the base. Gills broad, ventricose, 

 irregular, emarginate, slightly attached, dark ochraceous. Spores 

 dark ferruginous. Mycelium tawny. 



A very beautiful species allied to A. erinaceus and siparius, but 

 the colours are difi^erent, the stem is solid and not clothed like 

 the pileus, and the gills are emarginate. 



14. A. (Galera) crocosporus, n. s. Pileo membranaceo e conico 

 convexo, demum depresso viscido sordide fusco expallente sulcato; 

 stipite albo sericeo-nitente ; lamellis breviter adnatis e pallidis 

 ferrugineo-crocatis. Curt. no. 2867. On a damp house-mat, 

 Aug., South Carolina, H. W. Ravenel, Esq. 



Gregarious. Pileus an inch or more across, membranaceous,
