ADDITIONAL GUERNSEY FUNGI. 



BY E. D. MARQUAND, EX-PRESIDENT. 



During the past twelve months a very important addition 

 has been made to the list of Fungi published in last year's 

 Transactions. The record is made much more complete by 

 the finding of many winter and spring species which were 

 necessarily absent from the previous list, and among them 

 there are several of great interest and rarity. 



It will be remembered that last year I announced the 

 discovery in Guernsey of two species hitherto undescribed : 

 Clitopilus sarnicus and Verticillium Marquandii ; a third 

 species new to science has now to be recorded, — a remarkably 

 fragrant, ivory-white Agaric, discovered by Mr, W. A. Luff 

 on the cliffs at Icart, on January 3, 1898. To this fine 

 addition to the Flora Mr. Massee has given the name of 

 Omphalia Luffii, in honour of one of the most diligent col- 

 lectors of Guernsey Fungi. These three new species were 

 described by Mr. Massee in the Transactions of the British 

 Mycological Society for 1896-1897, pp. 20-24, as follows :— 



Clitopilus sarniCUS, Massee (sp. nov.) Gregarious ; pileus campanulate 

 then expanding until quite plane, subumbonate, often more or less de- 

 pressed round the umbo, slightly striate when moist, even when dry, 

 mouse-colour, paler with a ruddy tinge when dry, minutely silky -floccu- 

 lose, 2-3 cm. across ; flesh very thin. Gills rather crowded, 3-4 mm. 

 broad, plane nearly up to the stem, then suddenly decurrent, pinkish 

 salmon -colour. Spores nodulose, with an apiculus, 7-8 x 6p ; cystidia 

 absent. Stem 2-3 cm. long, 2 mm. thick, equal, slightly flexuous, even, 

 white, glabrous, minutely fistulose. 



On the ground among grass. Guernsey. Allied to Clitopilus undattts, 

 but differing in the slender, equal, white stem, and the absence of a grey 

 tinge in the gills. 



Verticillium Marquandii, Massee (sp. nov.) Patches broadly effused, 

 minutely velvety, pale lilac at first, becoming deep lilac or amethyst- 

 coloured at maturity. Vegetative mycelium creeping, branched, septate, 

 hyaline, slender, giving origin to numerous slender, erect, fertile branches, 

 which are either simple, or usually with 1-4 short, alternate, or opposite 

 branchlets, rarely in whorls of 3 ; tips of branchlets, also tip of main 

 axis bearing a whorl of 3-6 flask-shaped conidiophores. Spores smooth, 

 hyaline, lemon-shaped, solitary on the tips of the conidiophores, or rarely 

 in chains of 2 conidia, 3-3*5 x 1'5-2/y.
