INDIANA MUSHROOMS
Habitat; oak/beech woods. Summer into late fall.
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.
