Would mildly bacterial spawn cause the cracking on these mushrooms, or is there another cause?

Verticillium

Verticillium is a parasitic mold that can infect various mushroom species. It has multiple sources, including soil, plants, and flies. The severity and manifestation of Verticillium contamination can vary significantly.

The most common symptom of Verticillium infection is the appearance of brown spotting on the caps and stems of mushrooms. Unlike bacterial blotch, the spotting caused by Verticillium is dry, typically indented, and may develop a light gray fuzz in the center under high humidity conditions. The fungus often infects a specific side of a mushroom, causing growth to cease in that area. As healthy tissue continues to grow, it can lead to stem peeling, lesions, and cracking in the cap, which may result in a tilted appearance. When primordia (early stages of mushroom development) become infected, small "bubbles" of infected mushroom tissue may form. The infected tissue on both the bubbles and the growing mushrooms appears brown to gray and has a dry, leathery appearance.

Verticillium infection occurs when developing fruit bodies are exposed to Verticillium spores. Symptoms typically appear 7-14 days after exposure. Spawn is not typically a vector of contamination. Proper pasteurization of the substrate or casing material can destroy Verticillium spores, but maintaining good hygiene practices is essential to prevent recontamination.

The primary source of Verticillium spores is soil. Exposure can occur through airborne dust, insects, contact with contaminated surfaces (e.g., hands and clothes), and most notably, through aerosols created during misting. Even a single spray of water hitting a contaminated mushroom or surface can launch Verticillium spores up to two feet away.

Despite it's reputation, Verticillium infection is not common with indoor Cubensis and symptoms caused by bacteria are often mistaken for it.

how come some people have an open journal under their name and some people have a closed journal?

Some journals are worth sharing and others is for keeping your own personal notes, is my guess anyway

there is also a per-post journal setting for this, although IIRC mods and shit can still read it, so mods can go in there and peep game on all my dumb half baked ideas for threads I'm gonna make one day. Worked on one tonight

Yeah someone will surely have access so I'm not posting my tutorial ass shaving video there

When you guys use a microscope, what is your procedure for getting samples on the slides as sterile as possible?

langten69 said:

I just got a new microscope today and have only used them twice in middle school, so I just wanted to see what my myc looks like and figure out the standard protocol yall use

---

An easy and fast technique is to take some scotch tape on top of a colonized plate with the glue side down to get your sample and then placing the tape on a slide

they're not roots, but even roots can go in any direction also. They'll find their way, no worries.

Cool Thanks,



Do you know why this transfer mycelium is so slow? Transfer was 10 days ago

Even though i have the money to buy mason jars, i have 3_27gallon totes full of (salsa/sauce/misc.) Jars that I saved for mycology purposes...its like free containers bru, and yeah, slightly unscrewing the lids a bit works perfectly. I like modifying the lids with a filter patch and sometimes a self healing injection port for LC
