eastern tropics, is ochraeeoiis, waxy, resupiuate, 2-5 cm. long; basidia 

 5 X 40-60/u; spores 5 x 10-12/^, witli one septum in the center (Bull. 

 Soc. Myc. de Fr. 9:141, PI. 8, fig. 5. 1893). In the Curtis Herbarium 

 is a collection from Schweinitz (Bethlehem on Acer) labelled D. vires- 

 cens Fr., which looks a good deal like our No. 4075. His plants are 

 very small, pulvinate, much convoluted, blackish when dry, sordid, 

 smoky ochraceous when wet ; texture waxy or dense. I could get no 

 spores from the plants and no distinct basidia. 



4075. On oak baik, back of Athletic Field, February 4, 1920. Type. 



We include the following notes for the convenience of students : 



Bacrymyces syringicola B. lic C. A collection from Society Hill, S. C, labelled 

 B. Syringae Fr., in the Curtis Herbarium, bursting through the bark of dead lilac 

 twigs, is not a Dacrymyces, but is made up at least superficially of large more 

 or less rectangular bodies resembling parenchymatous cells. A collection of the 

 same thing from Sautee Canal, S. C. (Eavenel), is labeled D. destructor B. & 

 Rav. It was found on a dying pear branch. This last is supposed to be the 

 same as D. syringicola B. & C. by Massee. 



Dacrymyces violaceus Fr. is reported by Schweinitz from iSTorth Carolina on apple 

 wood. There is a bit of decorticated apple branch under this name in the 

 Curtis Herbarium, but there is api^arently nothing left on it of value. Fries 

 described the species as ' ' small, compact, subcompressed, gyrose, violaceous, 

 on trunks of pears" (Epicrisis, p. 592). 



Dacrymyces chrysocomus (Bull) Fr. is represented in the New York Botanical 

 Garden by a good collection from Bresadola on corticated pine twigs. The 

 plants are small, amber-colored, collapsed to a membrane; spores thick, divided 

 into about eight cells, 9.3-12 x 18-21^. Brefeld gives the spores of the species 

 as up to twenty-celled, 15 x oo/j.. We have not found anything like this. 



Dacrymyces conglobatus Pk. (Eep. 32: 37. 1879) is evidently not a Dacrymyces. 

 He also reports D. fragiformis. 



Dacrymyces fragiformis (Pers.) Nees. There is evident confusion here. In the 

 original description Persoon says : ' ' Subcompact, rounded, red, folds crowded, 

 somewhat lobed. When dry 4-6 lines broad, otherwise as large as an inch 

 across, color fading, internally pale. On bark of pine" (Syn. Fung. p. 622. 

 1801). His fig. 1, PI. 10, in Icon. Pict. shows the plants crowded, of good 

 size, reddish outside, white within. Quelet gives the spores as 40-60^ long, 

 triseptate (Fl. Myc. Fr. p. 17. 1888). Herter gives the spores as 20x7^, many 

 septate, and says the species is doubtful (Krypt. Fl. Mark B. 6:56. 1910). 

 See also Rabenhorst's Kript. Fl. 1:277. 1884. Albertine and SchAveinitz intro- 

 duced confusion by assigning to this species a form R carpinea, an entirely 

 different plant that grows (apparently parasitically) on the fruiting body of 

 the black, encrusting Ascomycete Diatrype stigma (formerly Sphaeria or Hy- 

 poxylon) on twigs of frondose wood. SehAveinitz reports this as T. fragiformis,
