| Tolypocladium ophioglossoides
|This is a small mushroom; longest here is 4 cm (about 1.5 inches), said to reach a
length of up to 8 cm. Very tough consistency but pliable. Several usually found
growing in one area; often found in mossy areas, probably due to ease of visibility.
The dark red-brown head of this mushroom is its fertile surface, the stroma,
producing and ejecting spores.

|The first image above shows a single ascus which contains eight ascospores lying
side-by-side; as can be seen in the second image showing a broken ascus. These
long (150-200 microns) and thin (2 microns)) ascospores are multiseptate (divided
many times) and produce 128 part-spores, each a viable spore. Last image is of
disarticulated part-spores which measure 2.5-3.5 x 1.5-2 microns. That's small!

|With age, Tolypocladium ophioglossoides will become completely black; the above
example was found in November attached to a cluster of Elaphomyces granulatus.
|If you dig very carefully you will find Tolypocladium ophioglossoides attached
to its host, the deer truffle, by a gold-colored thread of mycelium.
