C. sceptrum Fr. has been found by Sev. Petersen in Jylland 

 and C. diaphanus Quel, near Sorø. They appear from the 

 description to be almost identical. Until it is ascertained 

 whether they are really glabrous, or minutely setulose like C. 

 ephemerus, the question of their systematic position cannot be 

 settled. They (especially C. diaphauus) seem to have much in 

 common with C. ephemerus. 



C. congregatus, (Bull.). — A fungus very much like this species 

 I have met with in foliaceous wood, on grassy drive, growing 

 in large and dense clusters. I have not had the opportunity to 

 study it further, as it has not reappeared for several years. 



Additional note. 

 C. bisporus n. sp. 



Immediately before tbe going to press of this paper I have met with a 

 Coprinus of the C. ephemerns-type which differs from all other Coprini 

 examined b}' me in having constantly 2-spored basidia, and which I therefore 

 think deserves a specific name, although macroscopically it differs but very 

 little from its 4-spored allies. — Like the forms mentioned sub no. 27 a. it 

 grows as well on dung as amongst grass. Probably the large-spored 27 a II 

 belongs here. I add a brief description: 



Young cap 0,5—1,2 cm high, ovate, pallid (like C. disseminatus), apparently 

 naked, but set with minute, erect setulæ. When expanding it becomes grayish- 

 hyaline, radiately sulcate and at last somewhat recurved and diffluent. 



The gills are narrow, reach the stem and soon become blackish. The stem 

 is 3— 8 cm x 1—1,5 mm, glabrous, translucid. Setulæ on cap 60 — 120 n long. 

 Spores ovate-ellipsoid, 12 1 /,, x 6 l / 2 I- 1 opaque, blackish-brown (sporepowder black). 

 Basidia constantly 2-spored, 9 n broad. Cystidia inflated ovate, about 18 n broad. 



Fig. specim.: Hjallese, on rubbish-heap and horse-dung in wood July 

 1915. — Also met with on borders of road and green walk in wood in same 

 locality.
