Sample #35
Possible ID: Pezizomycete sp.
Classification:
Phylum Ascomycota
Subphylum Pezizomycotina
Class: Pezizomycete
Isolation and Culturing Methods:
This sample was collected during an air spore drop collection in the Grove on Bucknell’s campus. The spore drop plate was left outside to collect spores for seven minutes. This sample was extracted from the spore drop plate and put on a separate MEA plate.
Description of macroscopic and microscopic characteristics:
Hyphae regularly septate, without clamp connections, 4-5 um wide. Hyphae are white and are fuzzy. They grow densely on the plate, into the agar and up towards the plate lid. Hyphae appear to be reproducing via holoblastic conidiogenesis in which a single conidium is forming from a “pinched off” portion of the hyphae.
