Observation 98242: Hypomyces hyalinus (Schwein.) Tul. & C. Tul.

When: 2012-06-24

Collection location: Hunlock Creek, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

No specimen available

Atfirst IU thought this was a Blusher that had bee attacked by hypomyces. But the photo looks like it’s just an unexpanded button.

In a spot on my property where A. amerirubescens routinely fruits. (There was one right next to this.)

Weather has been hot and dry. I harvested the specimen and cross section revealed inner context that really had me guessing about whether this may be a type of puffball. Scraped off some of the mold on the surface, and under the scope the long fusiform spores (10-15 long with 2.5 < q < 3.2) support Hypomyces proposal.

Nice—hope to see it’s progress.

is A. amerirubescens, a favorite target of H. hyalinus. Newly posted photo was taken 6/25, one day after the first photo. Presence of parasitic mold is much more apparent.

I did not harvest this specimen.

I’ll return to snap a few more photos as it develops.

Do you have a photo of the cross section?
