HORROR WEEK- FOTD #144 : apple bolete! (exsudoporus frostii)

the apple bolete (also frost's bolete) is a mycorrhizal fungus in the family boletaceae >:-) it typically grows near the hardwood trees of the eastern US, southern mexico & costa rica. it was chosen for horror week due to its appearance being reminiscent of muscle tissue !!

the big question : will it kill me?? nope !! however, although they are edible, they are not recommended for consumption as it is quite easy to confuse them with other red boletes. ^^

e. frostii description :

"the shape of the cap of the young fruit body ranges from a half sphere to convex, later becoming broadly convex to flat or shallowly depressed, with a diameter of 5–15 cm (2.0–5.9 in). the edge of the cap is curved inward, although as it ages it can uncurl and turn upward. in moist conditions, the cap surface is sticky as a result of its cuticle, which is made of gelatinized hyphae. if the fruit body has dried out after a rain, the cap is especially shiny, sometimes appearing finely areolate (having a pattern of block-like areas similar to cracked, dried mud). young mushrooms have a whitish bloom on the cap surface.

the colour is bright red initially, but fades with age. the flesh is up to 2.5 cm (1.0 in) thick, & ranges in colour from pallid to pale yellow to lemon yellow. the flesh has a variable staining reaction in response to bruising, so some specimens may turn deep blue almost immediately, while others turn blue weakly & slowly.

the tubes comprising the pore surface (the hymenium) are 9–15 mm deep, yellow to olivaceous yellow (mustard yellow), turning dingy blue when bruised. the pores are small (2 to 3 per mm), circular, & until old age a deep red colour that eventually becomes paler. the pore surface is often beaded with yellowish droplets when young (a distinguishing characteristic), & readily stains blue when bruised. the stipe is 4 to 12 cm (1.6 to 4.7 in) long, & 1 to 2.5 cm (0.4 to 1.0 in) thick at its apex. it is roughly equal in thickness throughout its length, though it may taper somewhat toward the top ; some specimens may appear ventricose (swollen in the middle). the stipe surface is mostly red, or yellowish near the base ; it is reticulate — characterized by ridges arranged in the form of a net-like pattern."

[March, 2023] culture stains & snow days

It's not the best "microbiology" art, but it has a very interesting background. Two bacteria from two different clinical cases were inoculated on the TSCB medium. This metallic blue spilling bacterium is of course Pseudomonas aeruginosa. The yellow one (positive reaction on TSCB medium) is Vibrio metschnikovii isolated from chronic UTI in a dog. It was an unusual microbiological diagnosis. But what can you do when even your dog has a better holiday than you? Problems with urination (in this dog) began just after returning from the Mediterranean, the owners and the dog intensively used the charms of warm and salty water.

[Hotwheels gen. nov., a new ground spider genus (Araneae, Gnaphosidae) from southwest China]

The generic name refers to Hot Wheels, a collectible die-cast toy car made by Mattel, as the long, coiled embolus of this new genus resembles a Hot Wheels track; neuter in gender.
