other specimens which I have seen and it has the additional 

 characters published for L. furcellatum by Patouillard. 



These specimens are tough and certainly coriaceous rather 

 than fleshy, have dried hair-brown below, with final branchlets 

 pinkish buff, everywhere hairy with weak, hyaline hairs 1 n in 

 diameter, which protrude beyond the basidia except along the 

 tips of the branchlets; spores becoming pale ochraceous, even, 

 7-12X4J-6 fji, apiculate. 



The specimens of L. furcellatum of Berk. & Curtis, Fungi 

 Cubenses, are of two species. That collected in Cuba by C. 

 Wright, 831, is L. brasiliense; the other by C. Wright, 839, has 

 small hyaline, even spores 3-4X3 m but lacks the radiately 

 branched organs characteristic of L. brasiliense. 



Specimens examined: 

 Colombia: Bonda, C. F. Baker, 14, distributed under the name 

 Lachnocladium brasiliense. 



g. L. erectum Burt, n. sp. Plate 5, fig. 8. 



Type: in Ell. & Ev., Fungi Col., 808, copy in Burt Herb. 



Fructifications of the type arise in a cluster of three from a 



common point, soon repeatedly dichotomously branched, with 



branches erect, close together, coriaceous, com- 



O' /-% pressed, drying drab, clothed with a gray down 



< /p ^-^V_> whose hyphae are 50-200 m long; fertile tips of 



the branches cylindric, flexuous, solid, $-1 cm. 



Fig. 15. long, bearing the hymenium on all sides; spores 



L. erectum. very pale yellowish under the microscope, even, 



Spores, X 870. 6 _ 7X 3-3| fi. 



Cluster of fructifications 8 cm. high, 2\ cm. in diameter in the 

 branched portion; individual stems 1 cm. high, about 2 mm. in 

 diameter; branches about 1 mm. in diameter. 



On rotten frondose wood. West Virginia. September. 



L. erectum may be distinguished from the other species of its 

 genus in the eastern United States by occurrence on a woody 

 substratum, by its slender, erect habit of growth and appressed 

 branches, by the soft, downy pubescence of weak hyaline hyphae 

 which stand out at right angles from the stem and branches, and 

 by the small, oblong, apparently slightly colored spores.
