| Summary: | (A) Sound pine wood showing intact tracheid cell walls. (B) Advanced stages of soft rot from Fort Conger timbers with extensive soft rot attack and cavity formation within all secondary cell walls. (C) Wood from the Inughuit hut with a progression of soft rot attack exhibiting incipient stages of attack with small individual cavities in the cell walls (bottom of photo) and more advanced stages with many coalescing cavities (top of photo). (D) Advanced decay in wood from Henson’s hut with the S2 layer of the secondary walls completely riddled with cavities and many of the cavities coalescing into lager voids. (E) and (F) Soft rot in wood from the Inughuit hut showing advanced stages of decay with secondary cell walls almost completely destroyed but the middle lamella and S3 region of the secondary wall, the wall layer closest to the cell lumen, remaining. Bar = 50μ in A to E and 25μ in F.
