• The printed materials visible include:
• A leaflet titled "Parasitic Fungi" which describes parasitic fungi as organisms that feed on other living beings (plants, animals, humans), causing diseases (mycoses) and host death. It mentions about 10 thousand species, about 90% of which affect plants (smut, bracket fungi, ergot), and about 10% affect humans and animals, insects (candida, ringworm). It also states that they reproduce by spores and often in warm/humid conditions. The leaflet contains images of "Smut on corn", "Ringworm lichen", and "Cordyceps".
• A larger, open booklet titled "In the Kingdom of Mushrooms". This booklet indicates it was completed by a 7th "B" grade student named Korotkikh V.D. from the "Stolichny Lyceum". It also shows images and possibly diagrams related to mushrooms.

Summary: The messages concern a school assignment requiring students to create a booklet about mushrooms, with specific instructions and deadlines. The printed materials provide information on parasitic fungi and a general overview of the mushroom kingdom, likely as part of the assignment.
