Hypoxylon sp. with dark umber extractable pigments
Ethan Crenson, 26-01-2020 00:07
Hello all,
Last week in New York City I found this Hypoxylon with brick red surface pigments, fairly apparent perithecial mounds and dark umber KOH-extractable pigments. The ostioles are lower than the surface of the stroma. Perithecia are obovoid. There are yellow-brown granules between the perithecia—very apparent in horizontal section, but quite inconspicuous in vertical section. Unfortunately it must be quite old because I could find no asci (there were insect eggs inside some of the perithecia). Spores are brown/dark brown, germ slit is on the convex side and runs full spore-length, 9.5-13 x 5-5.5µm. Is it possible to know what Hypoxylon this is with the information I have provided?
