The usual sort of confusion…

with mushrooms getting shuffled from one genus to another. When in doubt, I generally use Index Fungorum.

Yes, I think NSW’s G. brunnea is the one with the brown saddle-like cap, and I think a cylindrical stipe, like G. esculenta. Seems like there is just more confusion if you have both Discina brunnea AND Gyromitra brunnea

I find plenty of G. korfii…

here in eastern NA. From what I have read about korfii, it’s like a smaller version of G. gigas (which may currently be called by a different name… maybe G. montana…?). Korfii also has smaller spores than the western Snowbank False Morel.

I also find what I call brunnea here in PA/NJ. Occasionally difficult to separate from korfii. But usually brunnea has the pinched saddle-like cap that is a richer brown color than korfii, with stipe easier to differentiate from “cap” than korfii.

Here’s an obs I believe to have settled as brunnea based upon spore features. This particular one is macro-similar to korfii. obs 164575. Note the sharp creases on the cap. Korfii tends to have more rounded folds.

Nancy Smith Weber’s concept

I used G. fastigata in the sense that Nancy Smith Weber does in “The Morel Hunter’s Companion.” As I recall, there was another species there referred to as G. brunnea, but I don’t recall its description. But I guess I’ll go with Michael Kuo’s ID here now.

I hope some other people take these on. The varieties found in the west, G. korfii and G. gigas also need some sorting out.

Hi Patrick.

Looks like a few of these False Morel species have been moved from Gyromitra into Discina. Also, it’s my understanding that “fastigiata” is no longer applied to an NA species, but I may be incorrect about this.

This one looks like what I would currently call Discina brunnea.
