Eriospora, n. g. 



Stroma multicellulare ; cellulis globosis poro unico communi 

 sporas filiformes tenerrimas primo quaternatim sporophoras coro- 

 nantibus effundentibus. 



438. Eriospora leucostoma. On dead leaves of Typha, Spye 

 Park, Wilts, Feb. 1850, C. E. Broome. 



Spots pitch-brown, very thin and diffused toward the edges, 

 not a line broad, marked in the centre with a punctiform white- 

 bordered pulverulent aperture. Stroma depressed. Cells vary- 

 ing in number, generally globose, but sometimes from the con- 

 fluence of one or more depressed. Spores very long, filiform, so 

 delicate that they wave from the minute currents formed by the 

 evaporation of the water in which they are placed for examina- 

 tion on the table of the microscope, at first seated four together 

 on short cylindrical sporophores, but soon falling off. 



Not unlike the foregoing species, but the spores forbid its 

 being placed in the same genus. It exactly answers to the genus 

 Robergea of the Ascosporous series.

439. Glaosporium paradoxum, Mont, in litt. = Myxosporium 

 paradoocum, D. Not. Mic. Dec. 2. fig. 10. On leaves of ivy, Pen- 

 zance, J. Ralfs, Esq. ; King's Cliffe. 



440. G. labes, Mont, in litt. = Asteroma labes, Berk. Brit. Fung, 

 no. 346. 



441. G. concentricum, Berk. & Br. = Cylindrosporum concen- 

 tricum, Grev. Scot. Crypt. Fl. t. 27. 



Authentic specimens lately forwarded for inspection by Dr. 

 Greville show the spores to be produced beneath the cuticle, and 

 to form little heaps by oozing out as in other species of Glceo- 

 sporium. The notion formerly broached, of its being a form of 

 Cystopus Candida, arose from a specimen in Sir W. J. Hooker's 

 herbarium received from Dr. Greville, but which unfortunately 

 was not the true plant, but a form of the common white rust with 

 cylindrical truncate spores. 



441*. Cheirospora botryospora, Fr. Summa Veg. Scand. p. 499 

 = Hyperomyxa stilbosporoides, Corda, Ic. Fasc. 3. fig. 89 = Stil- 

 bospora botryospora, Mont. Ann. d. Sc. Nat. 1837, t. 18. fig. 5. 

 Abundant on beech twigs, Wraxall, Somcrs., C. E. Broome ,
