HELOTIACEAE 

 Chlorosplenium aeruginosum (Oeder) De Not. Comm. Critt. 

 Ital. i : 376. 1864 

 Only the stained wood of this species was collected by Professor 

 Bethel, at Tolland, so that the identity of the species is uncertain. 

 Helotium citrinum (Hedw.) Fries, Summa Veg. Scand. 355. 



1849 



Common on rotten wood, Tolland and Geneva Creek Canyon. 



PHelotium populinum Fuckel, Symb. Myc. 316. 1869 

 The plants referred to this name are very minute and bright 

 lemon-yellow, at least in fresh specimens, and occur in abundance 

 on decaying leaves of Populus tremuloides. Fuckel's species is 

 described as subfuscous and we are therefore in doubt as to the 

 identity of our plants. 

 Helotium sulphuratum (Schum.) Phill. Brit. Discom. 161. 



1887 



Common in Geneva Creek Canyon on dead spruce branches 

 partially buried in the ground. Similar to Helotium citrinum. 



Dasyscypha arida (Phill.) Sacc. Syll. Fung. 8: 455. 1889 

 Peziza arida Phill. Grevillea 5: 117. 1877. 

 Lachnum Engelmanni Earle, PI. Baker. 1 : 25. 1901. 

 Dasyscypha fuscosanguinea Rehm, Ascom. 112 ; Ber. Naturf. Ver. 



Augsburg 26 : 30. 1881. 



This species was originally described from material collected 

 in Blue Canyon, Sierra Nevada Mountains, California, by Hark- 

 ness and Moor. The type has not been seen but a specimen in 

 the herbarium of the New York Botanical Garden collected by 

 Dr. Harkness in Blue Canyon, California, has been examined 

 and our Colorado specimens conform well with this. Dr. Rehm 

 (1. c.) states that this species is a variety of Dasyscypha fusco- 

 sanguinea Rehm. So far as we can see they are identical but 

 inasmuch as Dr. Rehm's specimens were distributed without a 

 description we cannot do otherwise than accept the name pub- 

 lished by Phillips. Numerous specimens were collected at Tol- 

 land and in the Geneva Creek Canyon and at first referred to 

 Lachnum Engelmanni Earle, which species was later found to be 

 identical with that of Phillips.
