Hi Larrry,
yabureta, ragged ... have a look at the bark of the akamatsu, which is the part of the tree Basho is comparing his mushroom to.

Matsutake - The name comes from the area where the mushroom grows, in a pine grove of Japanese red pines (akamatsu).
The broken parts of the hat look like the broken bark of akamatsu.
.
anyway, to translate matsutake simply as "mushroom" does not help the understanding.
