Observation 135140: Hypoxylon howeianum Peck

In my case someone else found a identic specie in Montreal, and brought them to me under the scope the arms bear conidia and are certainly the anamorph of the xylariaceae, whe tried to sequence it but it unfortunatly failed. maybe we should also try to scope a mature telemorph?
