TWO BRITISH MOULDS. 

 By M. C. Cooke, M.A. 



Verticillium agaricinum. (Bon.) " Agaric Verticillium." 



"White. Forming woolly tufts. Fertile flocci, septate, branched. 

 Ultimate ramuli verticillate, three or four in a whorl, thickened 

 below, attenuated upwards. Spores narrowly elliptical, obtuse, 

 triseptate, hyaline. Trichothecium agaricinum, Bonorden Handbk., 

 p. 99, t. y.f. 114. 



On decayed Agarics. Ken Wood, Highgate. Autumn. 



This mould agrees very closely with Bonorden's figure, and, 

 unless the genus Verticillium is to be restricted to such species as 

 have simple spores, it offers no features which would warrant its 

 removal to another genus. The snow-white threads form a dense 

 cottony stratum, covering the decayed Agaric. 



(Edocephalum roseum. Cooke. " Roseate GEdocephalum." 



Rose-pink. Effused, or in minute punctiform tufts, collected 

 together in irregular patches. Threads equal, head subglobose, 

 spores ovate or oval, smooth, attached by a slight apiculus. Cooke, 

 exs. No. 550. 



On old paper and rags. Millfield Lane, Highgate. Autumn. 



This is closely allied to (Edocephalum Iceticolor, B. & Br., but 

 differs in colour, as well as in the form of the spores ; features 

 which seem to be sufficient to characterize it as a distinct species. 

 The tufts are very minute, scarcely visible to the naked eye, except 

 as forming an effused rosy patch sometimes an inch or more in 

 diameter, on the discoloured matrix. 



Fungi from Stoves. 



In the Journal of Botany for March, 1873, Mr. Worthington 

 G. Smith has given descriptions of several new species of Hymeno- 

 mycetons Fungi, which he has met with from time to time in stoves. 

 These are doubtless of exotic origin, and although developed in 

 Britain, can scarcely be grouped with truly indigenous species. 

 Two coloured plates accompany the descriptions, which include the 

 following : — 



Agaricus (Pleurotus) gadinioides — on tree-fern stems (t. 129, 



Agaricus (Naucona) echinosporus — in orchidhouse (t. 129,/. 5-9). 



Marasmius subulatus — in dense patches on tree-fern stems (t. 129, 

 /. 10-15). 



Marasmius aratus — on tree-fern stems (t. 129,/. 16-20). 



Radulum Cyathea? — on tree-fern stems (t. 130,/. 5-8). 



Clavaria cervina — on and about tree-fern stems (t. 130,/. 9). 



Pistillaria purpurea— {t. 130,/. 10-12). 



Amongst known exotic species, Mr. Smith cites the elegant 

 Polyporus xanthopus, Fries., as having occurred on old wood at 

 Bull's nursery.
