|Habitat; oak/beech woods. Summer into late fall and not uncommon during winter months.
|These examples of Tolypocladium longisegmentum were very fresh (young) and
the stoma and stem exhibited vibrant coloration. Growing from the underground
fungus Elaphomyces granulatus. Without host, up to 5 cm long (2 in.) Compare
to older and larger specimens pictured below.
| Tolypocladium longisegmentum
|The spore producing cells (asci) of Tolypocladium longisegmentum. Eight
spores per ascus; spores are multiseptate (divided many times) and produce
eight partspores for a total of 64 per ascus.
|The cylindrical partspores of Tolypocladium longisegmentum. Partspores
measure 40-65 x 4-5 microns.
(T. capitatum, a similar looking mushroom, has much smaller partspores,
8-30 x 2.5-3um.)
|Section of stroma epidermis (outer surface) of Tolypocladium
longisegmentum. Note embedded flask or jug shaped perithecium
(where asci are produced), and the palisade structure of epidermis.
|Even more mature specimens. This collection was made in December.
