| Elaphocordyceps longisegmentis is a parasite of the underground (hypogeous) fungus Elaphomyces granulatus. Found in Elaphomyces habitat; oak/beech woods. |
| These examples of Elaphocordyceps longisegmentis were found in November 2006, in the same immediate area as the December 2004 collection below. Identification of Elaphocordyceps longisegmentis requires microscopic examination and measurement of its spores. Elaphocordyceps capitata (=Cordyceps capitata;Cordyceps canadensis) looks similar but has several microscopic differences. |

| These micrographs show the spore producing cells (asci) of Elaphocordyceps longisegmentis. Eight spores per ascus; spores are multiseptate (divided many times) and some produce eight partspores for a total of 64 per ascus. |
| The cylindrical partspores of Elaphocordyceps longisegmentis. Partspores measure 40-65 x 4-5 microns. Elaphocordyceps capitata has much smaller partspores, 8-25 (32) x 2.5-3. |
| Longitudinal section of stroma epidermis (outer fertile surface) of Elaphocordyceps longisegmentis. Note embedded flask or jug shaped perithecium (where asci are produced) and the palisade structure of epidermis. |
