86 Crossland : Recently Discovered Fungi in Yorkshire. 



Mr. A. D. Cotton, Kew, sends the following particulars of a 

 new species for insertion in these notes : — 



Clavaria crosslandii Cotton, sp. nov. 

 Plants small, iinhranched, isolated or fasciculate, greyish- 

 white or grey, becoming darker with age ; smell and taste slight, 

 pleasant. Cluhs very slender, brittle, 2-3 cm. high, 1-3 mm. thick, 

 pruinose, cylindrical, apex usually pointed. Stem hardly dis- 

 tinct. Flesh somewhat darker than hymeni-um. Internal structure 

 pseudoparenchymatous in transverse section, cells 5-8 /x diam. 

 Basidia 20-25x4-5 /a, contents granular, sterigmata 4, erect. 

 Spores hyaline smooth, pip-shaped, 4-5x2.5-3 //. ' 



Hab. — In short grass. Mulgrave Woods. (F.F., Sep, 1910 

 and 1911), ' Comm. C. Crossland and W. N. Cheesman.' [To 

 precede 1238]. 



' The grey colour and small size, which cannot fail to strike 

 the observer, are good field characters by which to recognise the 

 present species. From the drab-coloured C. tenuipes, it is dis- 

 tinguished by its slender, brittle clubs, and from C. fumosa by 

 its fasciculate instead of densely tufted habit. C. acuta, which 

 the new species resembles in size, habit, and texture, differs in 

 the complete absence of the grey tinge. The microscopic 

 characters confirm its title to specific distinction, the small 

 basidia and spores marking it off from allied species.' 



' Amongst continental species C. crosslandii most nearly 

 approaches C. affinis Pat. et Doas., but this plant differs, 

 according to the published description (no type is preserved), 

 (i) in the distinct stem ; (2) in becoming yellow on drying ; and 

 {3) in the slightly larger, punctulate spores. Though, on both 

 occasions, a few clubs only were met with, the specimens 

 agreed precisely, and were sufficient to show the essential 

 characters. It is a pleasure to name the plant after Mr. Charles 

 Crossland, not only because of his keen interest in the genus 

 Clavaria, but on account of his services to British Mycology 

 in general.' 



' Plantce simplices, minntce, sparsce, v. fasciculate, pallidce 

 V. cinerecB. Clavuli graciles, 2-3 cm. alt., 2-3 mm. eras., pruinosi, 

 cylindracei, apice acute. Basidia minuta, 20-25x4-5/^.; sporis 

 hyalinis, levibus minutis 4-5x2.5-3 /'.. Hab. ad terram gra- 

 minosum.' 



NEW TO BRITAIN. 



Lepiota medioflava Bond. ' Bull. Soc. Myc. Fr.' Tome 

 X., p. 59, pi. I (1894), fig. I. 



M. Boudier remarks : — ' This rather slender species re- 

 sembles others of the genus, but may be distinguished by its 

 white colour, pale yellow umbo, striate, finely tomentose pileus, 

 ovate uniguttulate spores : smaller than those of L. cepcestipes, 

 to which it comes near. This species has been found several 

 times in France, both in greenhoiises and in the open.'
