21. C. cortinatus n. sp. (Plate I, fig. i). 



Spores ovate-ellipsoid, 8 — 10x5 — 5 x / 2 \i, dark grayish -brown 

 (sporepowder black). Cells from mealy surface of cap globular 

 (30—50 \i), from edge of cap cylindric, forming fibrils about 

 10 — 20 u broad, slightly granulate. 



Fig. specim.: Hjallese, copsewood, on the ground among short 

 grass, July 1903. (Also occasionally met with in black mould 

 on stumps (Populus, Ulmus), Samsø and Fyn, 1903 — 07). 



Cap ovate, 4—7 mm high, when expanded convex or slightly 

 depressed, 0,8 — 1,3 cm broad, at first totally covered by a whitish 

 (slightly clay-coloured or sub-ochraceous), loose and scurfy meal, 

 when expanding radiately striate or grooved about halfway, not 

 diffluent. Towards the edge the veil is made up of minute, 

 downy fibrils; these at first connect the cap with the loose 

 downy-villous coating on the stem, which on large specimens 

 forms a very fugacious ringlike zone. Stem 3 — 5 cm x 1 mm, 

 with narrow cavity. The gills are free, at first pale, then grayish- 

 brown. — My plant has much in common with C. filiformis B. 

 and Br., but is twice as large. And C. f., according to Massee, 

 has much smaller spores (5x4 u.). 



22. C. curtus Kalkbr. (Plate I, fig. h). 



Spores oval, 10^2 — 12 i j 2 'X6 1 J2 — 7 1 / 2 > brownish-black. Sporepowder 

 black. Veil formed of clusters of subglobose, yellowish-brown, 

 somewhat granulate cells (13 — 20 [i broad).

 in pasture, Sept. 1901. — Also Hjallese, July 1915. 



As this characteristic species is only recorded from the Cape, 

 I think it advisable to give a brief description : 



Cap oval, 2 — 4 mm high, at first entirely covered by the 

 crusty, lighter or darker fox-red veil. When expanding it is 

 flat or slightly convex, fisso-sulcate, diaphanous, fusco-pallid, 

 3 — 9 mm broad, with a small, slightly depressed disc, and the 

 veil is broken up into very minute granules. The stem is short 

 (1 — 2 cm x !/ 3 mm), hyaline-pallid, pruinose. The gills are linear, 

 free, blackened by the spores. 



23. C. angulatus Peck (Plate I, fig. j). 



Spores obtusely pentangular, with a prominent apical wart, 

 7 — 7 x / 2 x 6 (u (short diameter only 5 jli), blackish-brown. Basidia 

 4-spored. Cystidia globose, about 22 |u broad. Cells from surface 

 of cap globose or broadly oval, 25 — 45 x 22 — 35 (a, those from 

 apex of cap slightly ochraceous. 



Fig. specim.: Langesø, on kitchen-offall (greasy paper, coffee- 

 grounds etc.) in shady backyard, gregarious and somewhat 

 cæspitose, July 1913. 



Cap at first ovate-oval, about 1 cm high, whitish, with a mealy 

 coating which is whitish, near the apex light brown and some-
