Thanks a lot. i meant microscopic slides with PAS or other stains
Mushroom Expert site says:
Astraeus hygrometricus looks like “earth stars” in the genus Geastrum, but its rays are “hygroscopic”; they cover the round spore case in dry weather but peel away from it in wet conditions. The inner (or “upper”) surfaces of the rays become finely cracked, and the surface of the spore case is matted-fibrillose. The spore powder, at maturity, is chocolate brown—and, under the microscope, the spores are much larger than the spores of Geastrum species.
The above may be the difference from Geastrum species. I am forwarding a few earlier posts from …, which may be from Astrarus & not from Geastrum.
Pl. have a look.
A Fungus for id from Chakrata:: NS June 28 : 10 posts by 4 authors. Attachments (1).
This is a fruiting body of any fungi.. this was very closely placed on soil and was to be almost “uprooted”, the picture was taken in same position as this originally was.. this is definitely not a fruit or a calyx as this looks like..
Any clues please..
Its a Earth star fungus !!
Geastrum species commonly referred as Earth star
Yes … has identified correctly.
I would have thought this to be Astraeus sp…
The Genus is Geastrum, sure, but unless the spore is examined it will be difficult to identify the species.
May be Astraeus sp. (as initially suggested by …) rather than from Geastrum as per discussions at another thread.
Yes … Its definitely Astraeus sp. Can be Astraeus hygrometricus
Geastrum triplex Jungh : 6 posts by 3 authors. Attachments (3)
Sharing some pictures of Geastrum triplex Jungh shot at Sundarijal on 24 July 2016 at 6000 ft.
Appears more closer to Geastrum floriforme
Out of 8 Geastrum recorded in Nepal Geastrum floriforme is not included. As such, I am not sure about and need expert idea
Than pl. try some other species.
Thank you … but I could not conclude the specific ID.
… … this is definitely not any Geastrum sp. It is surely Astraeus sp.
Thank you … I guess you are right since the book of Dr. Mahesh Adhikari says it is recorded in Sundarijal. Astraeus hygrometricus (Pers.: Pers ) Morgan
