 drical, about 2 [j. thick, not enlarged at the tip, brownish, 

 agglutinated together.

Geoglossum microsporum, Cke. & Peck, 25th Report of New 

 York Mus. Nat. Hist., p. 97; Phil., Brit. Disc., p. 39?; 

 Cooke, Mycogr., p. 11?. 



On the ground in scorched places tinder bracken (Pteris), 

 &c. 



The above account is drawn up from the American type 

 specimen sent by Peck to Cooke, and on which the species 

 was founded. In the original description in the 25th 

 Report, the spore measurements given are " -0007'-- 0013' 

 long." 



Some time afterwards Cooke again published the samo 

 species in "Mycographia," p. 8, tig. 11, as Geoglossum 

 microsporum, C. & P., and in the description says, " sporidia 

 05 x '01 mm.," adding "Figured from specimens com- 

 municated by C. H. Peck.'' I have examined every specimen 

 in the Kew Herbarium sent to Cooke by Peck from America, 

 but find nothing agreeing with Cooke's measurements, 

 which I imagine to represent an uncorrected mistake, as the 

 figures of the spores given by Cooke do not justify the state- 

 ment. Therefore I think it best to consider that no species 

 of Geoglossum exists having spores 50 x 10 /x. Phillips, in 

 Brit. Disc., p. 39, has unfortunately given Cooke's incorrect 

 diagnosis from " Mycographia," instead of the more ap- 

 proximately correct one from the 25th Report. It is evident 

 that Phillips had not examined the specimen ; finally, if 

 Mr. C. Bucknall's specimen found at Hanham, Clifton, and 

 which was presumably examined by Phillips, has spores 

 10 p. thick, it is not G. microsporum, but a new species which 

 would naturally be called Mitrula macrospora. 



Var. tremellosum, Cooke, Grev., iv. p. 109. 



Somewhat tremellose when moist; ascigerous portion 

 subcompressed, hollow, stem smooth, otherwise as in the 

 type.
