Observation 32475: Tyromyces fissilis (Berk. & M.A. Curtis) Donk
When: 2009-08-20
No herbarium specimen

Notes: When photographed there was a complete wind still. The mushroom smoked like a hot wet rag in icy air. But to photograph the phenomenon was not easy. Spores in the air can be (barely) seen in picture no.75354, upper left corner. Spore print white.

Lat.: 46.33479 Long.: 13.53083
Code: Bot_372/2009-2395

Habitat: Mixed woodland, nearly flat ground, cretaceous clastic rock (flysh), partly rain protected by trees canopies, mostly in shade, average precipitations ~3.000 mm/year, average temperature 8-10 deg C, altitude 435 m (1.450 feet), alpine phytogeographical region.

Substratum: fallen rotten deciduous tree, probably Acer sp., partly debarked, covered with mosses.

Place: West of Bovec, near a trail from station A of Mt. Kanin cable car to village Plužna, East Julian Alps, Posočje, Slovenia EC

Comment: Spore dimensions proved that my initial determination is wrong. The pictures show Tyromyces fissilis. Many thanks to Dip.ing. of Forestry Gregor Podgornik, Natural History Center (NAC), Tolmin, Slovenia for determination. Spores are shown on Fig. 80946. Their measured dimensions and spore dimensions of some macroscopically similar fungi from literature are shown on Fig. 80947.

I was told (personal communication with Mr. Anton Poler) it is listed in the Check list of mushrooms of Slovenia but under another name – Aurantiporus fissilis, the only species in this genus found in Slovenia. It is a relatively rare species.

Apparently yes.

It is not listed in A. Poler, Ed., Seznam Gliv Slovenie (in Slovene) (Check list of mushrooms of Slovenia), Assoc. of Mycological Societies of Slovenia (1998). I will contact people who are just now preparing a new edition of the Check list. Bernicchia (2005) states ‘.. not very common …’ for Europe and N. America and ‘.. found only sporadically..’ for Italy (neighboring Slovenia).

Nice obs!

I suppose it’s rare in your area too?
