Pores white, at length somewhat cream, or pallid, usually angular,

 20 x 5/z,; hyphae septate, with clamp connections. Rotten coniferous 

 wood. Nov. Jan. Not uncommon, (v.v.) "Some specimens which 

 seem to belong to this species are partly or totally reduced into a 

 floccose-pulveraceous state of sulphurous or pallid colour, which con- 

 tains abundant subglobose or ellipsoidal, apparently asperulate, 1- 

 guttulate, chlamydospores 5-7-5 x 4-5/z, not unlike those of Ptycho- 

 gaster albus, though more hyaline 1 ." "The conidia are smooth, not 

 asperulate, but have granular contents, which give a rough appear- 

 ance" Wakefield & Pearson.
