pendent, mostly entire, clothed with white villous down ; hyme- 

 nium even, pale reddish gray ; border slightly undulated. 



A very elegant and distinct little species, according exactly with 

 the description of Weinmann.

The species formerly published under this name in the ' En- 

 glish Flora ' is almost identical with Ncematelia nucleata, an Ame- 

 rican species, and very different from this. The figure in Romer's 

 ' Magazin fiir die Botanik/ part 4. tab. 4. fig. 14, is extremely 

 characteristic. This I had not seen at the time of the publication 

 of the ' EngHsh Flora.'

*293. H. citrinus, Vitt. 1. c. p. 21 ; Berk. Brit. Fung. Fasc. 4. 

 no. 284. Audley End, Essex, Rev. J. E. Leefe. Found abun- 

 dantly in Wiltshire by C. E. Broome, Esq. The yellow veins, sub- 

 fusiform, rough, dark-coloured spores, the frequently colom-ed spo- 

 rophores, and the strong cheese-like scent which communicates 

 itself to everything which it is near, are the criterions of this spe- 

 cies. The species which I have referred below to H. olivaceus is 

 sometimes very difficult to distinguish, especially when it has been 

 imbued with the odour of H. citrinus. It may however be knowR 

 by its reddish substance, larger cells, more transparent, paler and 

 smoother spores, which are more frequently abruptly acuminate. 

 When young H. citrinus is of a greenish yellow, but this soon 

 wears off when rubbed or exposed to air. 



In this species the sporophores occasionally become of a much 

 darker colour than the neighbouring cells, and have a resinous 

 appearance. In some specimens so circumstanced there is not 

 the slightest trace of spores, but the sporophores project beyond 

 the general surface of the hymenium, and do not show any indi- 

 cation of becoming bifid. In other specimens some of the sporo- 

 phores have two more or less imperfect spores extremely variable
