COMPTON, J. S., Michigan: 

 . Physarum bivalve. Hypoxylon. Sp. 



DAVIS, S., Wyoming: 



Helvella crispa. Tylostoma Americanum. Calvatia defodiodis (see 

 Note 161). Mycenastrum Corium. Evidently the largest and most com- 

 mon puff ball in the region. Polyporus varius (see Note 162). Peziza 

 acetabula. 



Catastoma subterraneum. Three forms or conditions distinguishable 

 to the eye can be sorted out from this very ample collection. Catastoma 

 subterraneum. The usual form with smooth, pale peridium. Catastoma 

 subterraneum. Form with darker peridium, probably unweathered condi- 

 tion. Catastoma subterraneum. Form with rugulose peridium. This was 

 named Bovista cellulosa by Ellis, but I cannot believe it is other than a 

 condition of Catastoma subterraneum (or originally of Catastoma circum- 

 scissum). 



Lycoperdon cepaeforme. Bovista plumbea. Calvatia lilacina, var. oc- 

 cidentalis. Tylostoma albicans. Merulius lacrymans. Badly infesting the 

 timbers of a cabin built of pine logs. Helvella elastica. Helvella atra. 



DEARNESS, J., Canada: 

 Clitopilus abortivus. 



DEMETRIO, C. H., Missouri. 



Guepinia spathularia. Tylostoma subfuscum. Xylaria hypoxylon 

 ( conidial ) . Exidia glandulosa. 



DOBBIN, FRANK, Shushan, N. Y.: 



Fomes igniarius. Daedelea confragosa. Fomes applanatus. Irpex 



cinnamomeus. 



DUTHIE, A. V., British South Africa: 



Polyporus versicolor. Lenzites trabea. Scleroderma, two species. 

 With thin peridium, Scleroderma tenerum. With thick peridium, Sclero- 

 derma cepa. Radulum lirellosum (see Note 163). Lycoperdon multiseptae 

 (see Note 164). Polyporus dichrous, Fries. Polystictus obstinatus, Cooke. 

 This specimen is the thick, Trametes form. The surface, usually pubescent, 

 is worn smooth. No. 34. Radulum (?). It looks familiar, but I cannot 

 place it. It is intermediate between Radulum and Hydnum. 



DUMEE, P., France: 



Fomes igniarius. Fomes conchatus (?) .Polyporus rutilans. Fomes 

 ribis. Fomes torulosus (cfr. Myc. Notes, Pages 470. =Fomes fusco- 

 purpureus). Fomes nigricans. Trametes pini. Daedalea confragosa. 

 Trametoid form ^Trametes Bulliardi. 



Fomes robustus. Fomes species. This plant has same context color 

 and microscopic characters as Fomes conchatus and Fomes salicinus, 

 which are said to be same thing. It is held to be a thick form of it. I 

 think it should have a name as a variety at least, but I believe it has not.
