2i8 Crossland : Recently Discovered Fiiiigi in Vorks/iire. 



but withdrawn at the last moment. It is so near to P. Adce 

 that we did not feel absolutely safe in publishing it as a new 

 discovery. The principal differences in the published descrip- 

 tions of P. Adce, and the Thorne Waste plant lie in the ascophore 

 of the latter being smaller, and its spores larger ; neither do the 

 colours of the disc quite agree. In AdcB they are said to be 

 * white, rosy- white, violaceous, or ochraceous.' The Thorne 

 Waste specimens were not so variable, being mostly pinky-coral 

 with, in some cases, a very faint tinge of violet ; in old specimens, 

 beginning to decompose, a trace of ochre made its appearance. 

 The spores measure 15-17 x 8 ju. Those of AdcE are given in 

 Cooke's * Mycoyr ' as 12*5 x 7 in PhiUip's ' Brit. Discomy- 

 cetes ' i3X7/>t, in Massee's 'British Fung. Flor.' 11-12x7^^. 

 If we consider previous examiners to have been slightly under 

 the mark, and ours slightly over, the mean between Phillip's 

 and our own measurements brings them pretty well into line. 

 No published characters include the size of the asci so that no 

 comparison can be made on that point. (These are 270-290 

 XII-12 /X, which certainly fits Massee's statement in ' British 

 Fungus Flora ' — asci narrowly cylindrical.'). Nor are the 

 hyphse composing the excipulum fully and definitely described. 

 All points considered, and allowing for variability, many fungi 

 are subject to, both in size and colour, it is much safer to record 

 the Thorne Waste gathering as P. Adce than to make a new^ 

 species of it, which may only lead to future confusion. It has 

 three previous records for the county, but we do not remember 

 having seen it before. 



Corrections. — The Omphalia hidlata recorded for Bolton 

 Wood, ' Nat.', Nov. '07, p. 398 is a misprint. It should read — 

 0. hulhtla 



Under Lachnea cinnaharina, 'Nat.,' Jan., 1906, p 82, for 

 spores 15-18 X 18 fi, read 15-18 x 8a.
