Remarks (internal):Phlebiella allantospora belongs to the subgenus Amyloxenasma that pro­duces amyloid basidiospores. Microscopically, this species is very similar to P. grisella (Bourd.) Larss. & Hjortst. but the latter is distinguishable from P. allantospora by the short-allantoid to almost reniform basidiospores. (4-)5-6x2.5-3 µm (Hjortstam et al., 1988).
