FIG. 3. Fungal inclusions. A−C in Biological Inclusions in Amber from the Paleogene Chickaloon Formation of Alaska

FIG. 3. Fungal inclusions. A−C (AMNH LC-D4): Hyphae of apparent resinicolous fungus (?Mycocaliciales), penetrating into core of amber. A. Most of hyphal mass. B, C. Different focal planes of same area, at higher magnification. D−G. Clumps of a hyphomycete with multiseptate phragmaconidia growing on substrate (AMNH GC-A8), possibly of a sooty mold (Capnodiales), or closely related to the enigmatic Eocene hyphomycete Casparytorula. D. Entire mass. E. Portion of fungal mass at higher (200×) magnification. F. Detail, 400×. G. Dispersed phragmaconidia adjacent to the sessile masses.
