Observation 191604: Kretzschmaria macrosperma (Mont.) J.D. Rogers & Y.M. Ju
When: 2014-11-09
No herbarium specimen

Notes: growing ~8ft. up a large tree, which was probably dead, but I’m not positive. Clasically xylariaceous, firm, carbonaceous consistency, but with liquid-filled, gelatinous chambers a few mm beneath the hard outer cortex, the likes of which I think can be present in certain species of Phylacia, but this was so much bigger and browner. Specimen saved, hopefully en route to SFSU soon.

Habitat: humid tropical forest, ~400m.

Substrate: undet. tree sp.

Collectors: T. Sanjuan, J. Araújo, E.R. Drechsler-Santos, B.J. Moreno, F.M. Freire K. Brothers & D. Newman

Recognized by sight: The conical or spine-like processes or umboes on the surface and the colour/texture make me think Kretzschmaria, as well as the HUGE perithecia. I wouldn’t be surprised if it was a new species though: a shame it’s not mature — without ascospores, it will be impossible to tell.
