OMPHALIA. 395 



Var. myochrous, Fries, Hym. Eur., p. 161. 

 MeruUus fuscug, Witliering, Arr., iv. p. 149. 

 Pileus rather fleshy, glabrous, brownish umber; stem 

 strigose and rooting at the base ; gills somewhat branched. 

 On sodden beech trunks. 



Omphalia infumata. B. & Br. 



Pileus obtuse, not membranaceous, greenish, then smoky ; 

 stem thin, yellow, gills few, broad, decurrent, distant, 

 yellow. 



Agaricus (Omplialia) infumatm, B. & Br., Ann. Nat. Hist., 

 no. 1851 ; Cke., Hdbk., p. 96. 



On bark among moss. 



Pileus 2 lines across ; stem 1 in. high, not a line thick, 

 dilated at the base, tomentose, especially below ; gills about 

 12, with smaller Intermediate. Allied to O.ujnbellifer a, hut 

 quite distinct from all its varieties. (Berk, and Broome.) 



There is no specimen of the present species in the Ber- 

 keley herbarium, Kew ; hence unfortunately the description 

 of this and other minute species, for a like reason, is im- 

 perfect. 



Omphalia buccinalis. Sow. 



Wholly white. Pileus about ^ in. acro.ss, trumpet-shaped, 

 soon plane or depressed ; gills deeply decurrent, triangular, 

 distant, white. 



Agaricus huccinalis, Sow., Fungi, t. 107 ; Cke., Hdbk., p. 

 96; Cke., niustr., pi. 272a. 



On twigs, &c. 



This is certainly no form of A. umbelUferus ; and it is too 

 fleshy to be the same as A. stellatus. It is, as Sowerby says, 

 not uncommon, and is in great perfection this Jan. 8, 1882. 

 It has the habit of A. ptycTiophyllus, Cd., a species not noticed 

 by Fries ; but the gills are not plicate. (Berk, and Broome.) 



Omphalia retosta. Fr. 

 Pileus J-|- in. across, flesh thin, plane then depressed, even 

 when moisb, polished and glabrous when dry, margin arched, 

 incurved, entire, umber ; flesh pale umber ; gills slightly de- 

 current, equally narrowed at both ends, distant, distinct, 

 pale umber ; stem up to 1 in. long, 1 line thick, equal, gla- 

 brous, hollow, tough, paler than the pileus.
