 KUSSULA GLAEOFLAYA Gl'OVe. 



This species was first described in the Midland Naturalist, 1888, 

 p. 265, from specimens found near the bo^^ at the top of Windlej 

 Tool, Sutton Farlc, in that year. A figure was sent to Cooke and 

 appeared in his Illusf rat ions of British Func/i as plate 1196 ; Cooli:e 

 added a sketch from a fungus found at Queen's Cottage, Kew, 

 which does not seem to represent the same species. I have since 

 found exactly the true form, keeping its characters unchanged, in 

 three other places : (1) the boggy ground by Bracebridge Pool, Sutton 

 Park; (2) the similar ground at Coleshill Bog, both in Warwickshire ; 

 and (3) a bog at Burnham Beeches, last year, i.e. four times in 

 thirty-one years. The fact now becomes evident that this fungus 

 grew, in each insfemce, in a i^lace of precisely similar character — namely, 

 on grassy ground among scattered trees on the edge of a Sphagnum 

 bog. It is evidently very uncommon, and does not seem to be a 

 variety of any other described species. It has a pileus approaching 

 that of B.Jingibilis Britz., pi. 10-18, but of a distinct chrome-yellow, 

 while the stem is like that of B. ochroleuca Pers., pi. 1049, but the 

 edge of the pileus never turns up as in that species. Massee, in his 

 Fungus Flora, iii. 65, mistakenly added to the description the 

 word " Acrid ? " A revised description is appended : — 



Bussula claroflava mihi. Pileus 5-10 cm. across, firm, convex, 

 then depressed, margin even or faintly striate, turned down even when 

 old, deep chrome-yellow, paler on the margin, stained here and there 

 (where abraded) with a rufous tinge ; flesh yellow beneath the cuticle. 

 Stipe 5-6 X 2\ cm., white, spongy within, somewhat granular, occa- 

 sionally stained with pale chrome-yellow patches when young, rugose 

 exactly as in B. ochroleuca and ultimately becoming covered with 

 dark-cinereous streaks as in that species. Gills rather thick, straight, 

 not forked, but often joined in pairs near the stem, obtuse and broad 

 in front, narrowed behind, adnexed, altogether tinged with pale 

 yellow, then becoming pale subochraceous ; cystidia elliptic-lanceo 

 late, not much projecting. Spores globose, echinulate, 8-9 ^ diam. 



On grassy ground among trees on the margin of Sphagnum bogs. 

 Flesh of pileus firm, but cheesy; smell faint, but not unpleasant; 

 taste becoming unpleasant, but not acrid, with age ; colour of pileus 

 rich, pure, and bright. 



Boletus sangijii^eus With. 



In his Botanical Arrangement of British Flants, ed. 2, iii. 414, 

 Withering described what he called the crimson Boletus (B. san- 

 guineus) from Edgbaston Park. No one else seems to have met 

 with a fungus exactly agreeing with his description, but this summer 

 I had the pleasure of finding ni my own garden, which is less than a 

 mile distant from Edgbaston Park, what is evidently the same plant. 

 The description is as follows : — 



Boletus sanguineus With. Pileus 6-7 1 cm. across, convex or
