Jakob E. Lange: Studies in the Agarics of Denmark. II. 23 



This is one of the few of the larger agarics, which grow on 

 cultivated land. Occasionally the cap is more prominently um- 

 bonate than shown in my figure, thus to a certain extent recall- 

 ing the L. umbonata-type. 



|3. METASPOHÆ. 



4 a. L. rhacodes (Vit). 



Spores ovate-ellipsoid, 8V 2 — 10 x 6u (or 9—11 < 6). 



Fig. specim.: Fruens Bøge, plantation of Picea, Oct. 1896. — 

 Very common, often rather numerous, especially in woods of 

 Picea, rarely found in foliaceous woods, under hedges etc. — 

 Blytt (Norges Hymenomyc.) makes it a subspecies of L. procera; 

 but this view I cannot share. — Massee (Europ. Fungus-Flora) 

 erroneously gives the dimension of the spores as 14 x 8 [i and 

 says the flesh turns brown (not red). 



4 b. L. rhacodes var. puellaris Fr. 



Spores 8—9 x 5— 5V 2 P, oval. Cystidia (1914) obovate— bottle-shaped, 

 about 16 u broad, occasionally with a somewhat protruding apex. 

 Fig. specim.: Gerup near Holstenshus, wood of Picea, Aug. 

 1902. — Rarer than the main type, smaller, almost pure white, 

 flesh not turning saffron-red. Although this is a very character- 

 istic plant, its total separation from L. rhacodes cannot be jus- 

 tified, as there are numerous intermediate forms. L. Olivieri Barla 

 appears to be such a one. 



5. L. naucina Fr. {Ag. læuis Krombh.). 



Spores broadly ovate, 8— 9 1 /, X 57 4 — 5Va r 1 » with a lar § e cen . tral 

 drop. When seen under the microscope they have a very slight 

 pinkish tint, but the sporepowder is white. — Cystidia about 

 55 u long, 10 — 11 jit broad, club-shaped; basidia 4-spored. 



Fig. specim.: Hjallese, on lawn, border of flowerbed, Aug. 

 1902. — Rather rare and often solitary in gardens, under hedges 

 (and once in a wood of Picea), Aug. — Oct. 



The cap is smooth, either absolutely glabrous or (sub lente) 

 minutelv fibrillose-floccose. The gills are white, but generally 

 turn somewhat pinkish The ring is very narrow, free (at least 

 in mature specimens). 



The best and fullest description of this plant (which is the 

 bearer of almost a legion of names) is given by the American 

 botanist Atkinson (Studies and Illustrations of Mushrooms). The 

 description of Annularia læuis fits my plants exactly (except that 

 the spores are said to be pinkish); and with Quélet, Ricken and 

 others I regard it as synonymous. That also L. densifolia Gill. 

 L. pudica Bull., L. Schulzeri Kalkbr., L. leucothites Vit. etc. are 

 identical seems to me highly probable. The Psalliota cretacea 

 figured in Fries' »Ätliga och giftiga Svampar« is also very much 

 like my plant.
