FUNGI. 3 



jEcidium Sommerfeltii, Johans. Near Pagosa Peak, 15 

 Aug., on Thalictrum ; n. 11. 



GYMNOSPORANGIUM, sp. At Pagosa Springs, 28 July 

 (immature), on juniper ; n. 81. These are conspicuous 

 galls, somewhat like those of G. globosum, but probably not 

 of that species. They are also quite different from either 

 of those uncertain forms taken in 1898, of which some ac- 

 count is given in PL Baker, i. 19. 



PHRAGMIDIUM OCCIDENTALE, Arthur, n. sp. I. ^ 

 hypophyllous, round, often 1 mm. across, at first waxy, on 

 pale-yellow spots: eecidiospores concatenate, orange-color, 

 fading to pale-yellow, round-elliptical, prominently warty, 

 19-24/u broad, by 24-30/x. long ; paraphyses forming a bor- 

 der, incurved, colorless, nearly terete. 



II. and III. Hypophyllous in tufted groups. Uredospores 

 obovate, echinulate upon small papillae, 18-22/x broad by 

 26-28/A long, pores about 8, scattered ; teleutospores cylin- 

 dric, nearly black, 5-7-septate, surface tuberculate, 85- 

 110/A long; apex rounded, usually bearing a conical nearly 

 colorless apiculation ; pedicel nearly colorless, enlarged be- 

 low, as long as, or by one-half longer than the spore. 



Mountains near Pagosa Peak at 9,000 feet, on Rulus 

 Nutkanus, 3 Aug. ; n. 48. The same as the P. Rubi- 

 Idsei of PL Baker, i. 20, that is, Baker, Earle & Tracy's 

 n. 1043 ; and both these collections are chiefly aecidiums. 

 The ascidium of this species with its warty spores is per- 

 fectly characteristic. It is Peck's Lecythea speciosa (after- 

 wards transferred to Uredo by De Toni in Saccardo's Sylloge, 

 vii. 860), which was collected by T. S. Brandegee more than 

 twenty years since (Conf. Bot. Gaz. iii. 24), on Rubus delic- 

 iosus. The species was issued in Ellis & Everhart's distri- 

 bution, n. 3425, on Rubus Nutkanus, from Sisson, Calif.
