Description

Common Coelomycetes on old fallen cones of Picea

exact host in this case a bit unclear, either Picea abies of Picea pungens, which are both commonly planted in the area

conidiomata, immersed or somewhat erumpant, opening from a large irregular slit, conspicuous on scales of the host.

Conidia produced in basipetal chains (in which the youngest conidia is at the base of the chain). Chains are fragile, and break readily and. Conidia birostrate (appendages at the top and bottom), and often with various protuberance on the sides. Conidia smooth, dictyoconidia, with several lateral and longitudinal septa, in the center. Conidia pigmented, but paler on the rostrums and protuberance.

Conidia measure 25 - 40(48)µm x 12 - 22 µm (avg = 31.7 x 16.8).

Common on this substrate
