Finally Corda illustrates and describes a second species of Berk- 

 eley's, viz. — 5, coarctatnm, from Swan River in Southwestern 

 Australia, the same locality whence the original specimens of the 

 preceding species also came. S. coarctatnm seems to be close 

 to the plant described below under the name of .S'. tennipes and 

 its characters will be discussed in that connection. It is certainly 

 some considerably different from both the species mentioned 

 above. There is one other type which especially concerns us in the 

 present consideration and that is the S. Mattirolanus which is the 

 type of the genus Elasmomyces of Cavara (cf. Malpighia, 1898). 

 This genus is subsumed under Secotium by Fischer (loc. cit.) but 

 with the statement that it is doubtless to be considered independ- 

 ent, only the difficulty at present is to determine just which of 

 the described species of Secotium are to be associated with it as 

 well as perhaps the exact lines of demarcation between the two 

 genera. The species, to be described below under the name of 

 Elasmomyces rnssnloides, is very close to Cavara's plant and a 

 farther discussion will be found in connection with the description 

 of it. Of the other species referred to this genus few are 

 known to me from actual specimens. The widely distributed 5*. 

 acuminatum (or ^S. agaricoidcs Hollos) has not occurred to me 

 nor does it occur in Californian collections, unless indeed, as 

 hardly seems probable from the descriptions, it is identical with 

 S. nuhigenmn, Harkness, as Hollos supposes (cf. Hollos, Die 

 Gastromyceten Ungarns, p. 37, 1904, under 5. agaricoidcs, also 

 Lloyd, Mycological Notes, p. 139). Hollos has also referred 

 under the same species the 5. erythroce phahim Tulasne, a species 

 collected by myself in New Zealand, which seems certainly amply 

 distinct from the Hungarian plant, at least. A careful search for 

 the type specimen of 5". nuhigcnum, Harkness, in his collection in 

 the Herbarium of the California Academy of San Francisco, even 

 before the bulk of that collection was destroyed by the fire follow- 

 ing the earthquake of April iS, 1906, failed to disclose it and there 

 seems to be no doubt that Harkness failed to retain, or at least, 

 to carefully preserve it. The Secotium Texense B. & C, as well 

 as the S. dccipiens Peck, seem properly to be referred to the genus 

 Gyrophragmium as .has been done (cf. Lloyd, loc. cit. pp. 154 and 



197)- 



Tn all there seems to be only six species of those credited to 

 this genus which have been referred to as having been found in 

 the United States, vife. : 



S. texense B. & C, now referred to Gyrophragmium. 



6". decipiens Peck, now referred to Gyrophragmium. 



^. nuhigenum Harkness, which has been referred, but probably 



erroneously to S. acuminatum Mont. 

 S. Warnci Peck, which seems by unanimous consent to be referred 



to S. acnminatum Mont,
