Armillaria mellea, (Vahl) Fr. 



Note. The sclerotioid condition of this species is the Rhizomorpha sub- 

 corticalis of older mycologists and we have for convenience inserted here the 

 North American references to that Rhizomorpha but without intending to 

 imply that in all cases cited the Rhizomorpha belongs beyond doubt to Armil- 

 laria mellea. 



A difficulty in the synonymy arises from the fact that while Armillaria 

 mellea normally has an annulus, specimens are occasionally found belonging 

 undoubtedly to this species but in which the annulus is wanting. 



There are other cases of forms referred to Clitocybe by some writers in 

 consequence of the absence of an annulus, although in other respects cer- 

 tainly closely related to Armillaria mellea. Whether such forms are to be 

 regarded as distinct species or merely as forms of Armillaria mellea is a 

 matter of individual judgment. Peck in Rept. N. Y. Mus. 46: 134 (54). 

 Dec. 1893 proposed the name Armillaria mellea, var. exannnlata to include 

 such forms. Later in Rept. N. Y. Mus. 51 1 : 284,302. 11 Feb. 1899 he 

 expresses the opinion that Clitocybe monadelpha, Morg. is distinct. We have 

 here brought together all the references to Clitocybe monadelpha and Clitocybe 

 aquatica since they need to be consulted in connection with Armillaria 

 mellea. 



It should be remarked that this species was placed by Karsten (1879) i' 1 

 the genus Armillariella characterized by an annulus and decurrent gills as 

 distinguished from forms like Armillaria robusta, (A. & S.) Fr. in which the 

 gills are not decurrent.
