surculos foliaque marcida mycelio floccoso affixus. Lamella latiusculae, horizontals, dente obscuro adnata?, subdis-tautes, quandoque furcatae. Spores oblique ellipticae, sub lente aureo-fuscas, nucleo parvo globoso. Margo pilei interdum reflexus discusque exinde depressus, tunc etiam lamellae, ni caute perscrutentur, libera; habeantur.
This species is allied to Ag. innocuus, Tasch, and Ag. cerodes, Fr. From the latter it differs in its solid stem; from the former, in its decidedly carnose umbonate pileus.

4. kGAXiCVsfascicularis, Huds., Fl. Angl. p. 615. Fries, Ep. p. 222.
Hab. Hermite Island, Cape Horn ; on the trunk of a dead tree, Mr. Davis.
A single specimen only was found.

Hab. Falkland Islands ; Gaudichaud.
This species was not met with during the visit of the Erebus and Terror. Ag. Glebarum could not have been considered as belonging to the subdivision of Coprini. The pileus is said by Persoon to be broader, and the stem shorter than in Bulliard's figure.
2. COPEINUS, Pers.
1. Coprinus Flosculus, Berk.; minimus, tenerriruus, pileo glabro ovato demum expanso hemisplierico fisso sulcato vertice depressiusculo, stipite brevi, lamellis liberis paucis linearibus remotis. (Tab. CLXII. Fig. II.)
Hab. Berkeley Sound, Falkland Islands ; on dung.
Pileus 1-i- lin. altus, 1 lin. latus, ovatus, profunde ex ipso vertice sulcatus, interstitiis striatis, glaber, subgriseus, margine crenulato, demmn expansus, hemisphericus, fissus. Stipes % lin. altus, filiformis, prinmin leviter ad basin turgidus, demum aequalis. Lamella primarise subdecem, libera;, remotae, lineares. Spora ovatse, atro-purpureae.
A minute Coprinus, belonging to the same section with Coprinus Hemerobius, but differing from it and from the other species of the section in various characters. It resembles in habit C. Hendersonii, Berk., but wants the ring which is characteristic of that species.
Plate CLXII. Tig. II. — 1, Coprinus Flosculus, of the natural size ; 2, ditto : — magnified ; 3, hyinenium, viewed vertically with the spores on the sporophores ; 4, spores : — highly magnified.
3. POLYPORUS, Fries.
1. Polyporus versicolor, Fr., Ep. p. 473. Berk, in Ann. Nat. Hist. vol. iv. p. 292.
Hab. Falkland Islands ; on the underside of timber, C. Darwin, Esq. This can scarcely be considered indigenous. The mycelium in all probability existed on the timber when imported.
4. CORTICIUM, Fries.
1. Corticium tretnellinum, Berk.; confluenti-effusum, gelatinosum, pellucidum, candidum, quandoque opacum, subtiliter pruinosurn, siccum non rimosum decoloratum.
Hab. Hermite Island, Cape Horn ; on bark of the Deciduous Beech in damp woods.
