100 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 



flexuosis nodulosis sursum sporis oblongis breviter concatenatis 

 terminatis. On leaves of Fumaria officinalis, King's Cliffe. 



Gray, forming a thin stratum ; flocci erect, flexuous, somewhat 

 nodulose, terminated by one or more short rows of elliptic-oblong 

 spores. 



Nearly allied to C. rectum, Preuss, but distinguished by its 

 less rigid habit and more flexuous paler stems. It approaches 

 the genus Dendryphium. 



516. C. lignicolum, Corda, Ease. 1. tab. 3. fig. 206. On dead 

 wood, Apethorpe, Norths. 



The spores in this species are very opake. Our plant seems 

 exactly that of Corda, but it is a doubtful Cladosporium. 



517. C. nodulosum, Cord. Ic. Fasc. 1. tab. 4. fig. 212. On the 

 stem of some herbaceous plant, Wraxall, Som., Feb. 14, 1845, 

 C. E. Broome. 



Remarkable for the alternate projections on which the spoi'es 

 are seated. 



518. Camptoum curvatum, Lk. Sp. 1. p. 44; Berk. no. 310. 

 Spye Park, Wilts, on Scirpus sylvaticus. 



519. Gonatosporium Puccinioides, Corda, Fasc. 3. p. 8. tab. 1. 

 fig. 18. On various Carices, Wiltshire and Somersetshire, as at 

 Spye Park and Batheaston. 



This must not be confounded with Arthrinium Sporophleu7n, 

 which has been published by Desmazieres at no. 602, under the 

 name of ^. Puccinioides, and is No. 311 of the 'British Fungi.' 



520. Aspergillus dubius, Corda, Ic. Fasc. 2. tab. 11. fig. 77. 

 On rabbits' dung, King's Cliffe, Nov. 16, 1842. 



In this very curious species the head is covered with linear 

 processes, each of which is surmounted by four sterigmata, on 

 which are developed the chains of spores. Corda does not seem 

 to have observed the quaternate processes. 



521. Botrytis infestans, Mont. Vlnstitut, 1845, Tp.SlS. Abun- 

 dant on the under side of the leaves of potatoes since 1845, pre- 

 vious to which it had not been observed in this country. It has 

 occurred also on Solanum Dulcamara, Anthocercis viscosa, and on 

 Tomatoes. 



It is unnecessary to enter into the question how far this mould 

 is the cause of the potato murrain. The subject is discussed at 

 length in the first number of the Journal of the London Horti- 

 cultural Society. 



522. B. UrticcB, Libert MSS. On leaves of the common 

 nettle, Tansor, Norths. 



Patches small, orbicular, grayish lilac, flocci loosely divided 

 above, branches forming an acute angle, extreme ramuli simple 

 or forked, sometimes curved, very rarely inflated. Spores large, 

 ovate, apex papilla^form. Allied to the last, but distinct. When
