Interested in science, especially physics, evolutionary biology, psychology. Hunting fungi mostly not to eat them, a bit of an amateur mycologist. Chess noob. From Czechia.
Dnešní nález (do druhu neurčená voskovka). Voskovky bohužel asi brzy utne mráz, ale vyrazit na houby jde po celý rok.

Cuphophyllus russocoriaceus (Cedarwood waxcap) smelling strongly of cedar. Locally redlisted in Czechia as EN (although probably not that rare on endangered, still one of the "better" waxcaps here). 2nd locality for me.

Not sure what's that (there is one thing that came to my mind that is not known from Czechia and I also got a tip from a pro mycologist who was interested in getting a specimen) but I love the color.

I remember and invitation to a fungi walk with expected distance and time noting that 1 km/h is Fast & Furious for mycologists. (Not using exactly these words.)

Here some "mainstream" Hygrocybe conica s. l. in a good waxcap season (2023). Plus a forest H. conica s. l., I have never seen an other waxcap that conica group in a forest (although it is mentioned for some), conica group three times. I'm wondering if those from forest are different.

These might be Hygrocybe conicopalustris, possibly one of those disctinct species (but I haven't found whether it's proven to be a separate species and if there isn't more) characterised by small size and ecology (wet grasslands / bogs).

Rule 1: Anything looking barely like R. satanas is Satanas (capital S mandatory). Rule 2: Tylopilus felleus (not looking at all like R. sanatas) is Satanas. Rule 3 (optional): R. satanas is S. luridus or something.
