No host, no micro, no sequence. How is this “Promisingly” a member of a genus of primarily truffle parasites, which looks nothing like any of the known, truffle-parasitizing members of that genus?

The collector would not have known to look for an insect host. In Senguio they pay local people a fixed price per kilogram to collect mushrooms for the fair.

tough call

but given the size and fleshiness of the stroma, assuming it’s an entomopathogen, it would have to have been growing on a comparably large (and fleshy) host, making it unlikely to be overlooked by the collector.

Yes I leave a scope down there so I do not need to carry it on the plane every time. We usually hunt mushrooms all day and look at them all night. I intended to scope this one but I got distracted and no pics ended up on my cf card. I am back in the US now, I will take a closer look at this sample next year. A pic of the scope is here.

are different.
Long and thin in Cordyceps, almost globose in Hypocrea.

it does look like it has perithecia…if one didn’t collect the potential host truffle, how does one tell the difference between Podostroma/Hypocrea and
Cordyceps in hand or under scope?

Possibly a young Tulostoma specimen that has yet to develop it’s apical pore.
