I’m looking forward to find this

With limited skill but plenty of willingness to work, I’ll try my best to do microscopy when I find this or others. Thank you for the information you provide. Now, I have T.capitatum, T. longisegmentum, T. valliforme, and T. fractum to differentiate which is good.

In my experience…

and according to what I believe to know about these species, T. longisegmentum has a dark glossy cap obs 59378 and T capitatum has a duller browner cap obs 114090.

T. valliforme, also similar to capitatum, is a new name for me… as are the other species mentioned via the jstor link provided in Herbert’s comment. Apparently, T. fractum is yet another similar species obs 304171.

C du Q offers spore-segment data as a means of distinguishing valliforme from either capitatum or longisegmentum. But (perhaps because of something lost in Google-translate) the C du Q explanation does not make sense to me.

Index Fungorum includes each of capitatum, longisegemntum, valliforme, and fractum as currently valid species names.

though I suspect that closer scrutiny of these will reveal more species than the two most common field guide IDs. exhibit a

can you do a microsopic examination of the host?

please provide a reference for “head shininess” being a diagnostic character for differentiating between T. capitatum and T. longisegmentum

These look like textbook

Tolypocladium longisegmentum

I did not identify those tubers

and I don’t know what Tuber canaliculatum is. I called them Tolypocladium capitatum because it was the only name I found from field guide. After Danny suggested they might be Tolypocladium longisegmentum, I know I’ll have to find them again and check spores to confirm their identity.

They did have shiny heads. So, this is another way to differentiate them. Thank you!

What is the host?

Is that Tuber canaliculatum?

Thank you for giving me another similar species to “worry”

I’ll do the microscopy to see what part spores are. There is always something new to learn.
