Minutus, totus aleuriatus niveus ; pileo conico-campanulato ; stipite filiformi ; lamellis 

 an<nistis adscendentibus. 



Bermudas. — Endemic. On small twigs, Devonshire Marsh- — Moseley. 



Scarcely a Hue high ; stem half to one inch high, covered, as well as the pileus, with 

 white mealy particles. Very delicate. 



Agaricus (Mycena) corticola, Schum. 



Agaricus (Mycena) corticola, Schum., Fl. Saell. n. 4689 ex Fries, Hymen. Europ., p. 152 ; Ic. Fung., 

 t. 85 ; Cooke, Illus., t. 164, A. ; Berkl. in Journ. Linn. Soc. Lond., xiv. p. 351. 



Bermudas. — On dead wood — Moseley. 

 Northern hemisphere. 



Agaricus (Entoloma), sp. Berkl. 



Agaricus (Entoloma) sp. Berkl. in Journ. Linn. Soc. Lond., xiv. p. 351. 



Bermudas. — A single specimen only, in very bad condition — Moseley. 

 It belongs clearly to the same section as Agaricus nidorosus, of which it has the 

 irregular spores. 



Agaricus (Nolanea) Delictus, Berkl. 



Agaricus (Nolanea) helictus, Berkl. in Journ. Linn. Soc. Lond., xv. p. 48. 

 Pileo profunde umbilicato sericeo ; stipite torto ; lamellis primum dente decurrentibus, 

 demum adnexis ; mycelio candido. 



Bermudas. — Endemic. On rotten leaf-mould — Moseley. 



Pileus about one inch across ; stem one and a half inch high, slender. Very much 

 wrinkled ; when dry, of a pale umber, sometimes browner towards the margin ; spores 

 irregular, 0"0003 inch long. 



In very young specimens the stem is darker ; but without any information as to its 

 colour when recent, its exact affinities cannot be ascertained. 



1 We are indebted to Dr M. C. Cooke for assistance in drawing up the enumeration of this group.
