Spore allergies are usually multi-allergic, but still have relatively few symptoms of spores.
In spring and summer, there are many allergens in nature that cause respiratory symptoms for the outdoors. After the flowering of the pujo in the late summer, the condition of many becomes easier. However, some also sign in the autumn forest due to the spores of cap fungi.
Usually, people with symptoms of fungal spores already suffer from several different allergies.
- It is typical for a person to first develop pollen allergies, animal allergies, and other allergies. Then another fungal spore allergy, says Johannes Savolainen, Professor of Clinical Allergology at the University of Turku.
In the humid and warm late summer, allergy sufferers’ first symptom of mold spores, and during the mushrooming season, spores of parent fungi, or cap fungi, cause symptoms.
A large proportion of the forest mushrooms that end up in the fungicide basket are cap mushrooms. According to Savolainen, the spores of allergy-causing sorrel and crumbs are abundant in the autumn forest.
Spore allergies are also familiar to Tiina Vitikainen, who works as a research coordinator at the South Karelian Environmental Institute.
- If you collect a lot of ducks and crumbs, and then you pour a mushroom basket on the table in the kitchen, then you can get symptoms if you are sensitive to fungal spores, Vitikainen describes.
The South Karelian Institute of the Environment is the national health organization’s research unit of the Allergy, Skin, and Asthma Association.
According to Savolainen, asthmatics also say that they sometimes suffer from shortness of breath in the autumn forest. Although fungal spore allergy is known, it is not as common and severe as, for example, pollen allergy.

Fungal spore allergy has been little studied.
There is little research on fungal spore allergies, but it has been estimated that about 1–2 percent of Finns would get symptoms from them.
Fungal spore allergy has been studied in the 1960s and 1970s. The study’s stagnation is indicated by the fact that Savolainen and his colleague published an article on mushroom allergens in the medical journal Allergy in 1988 and said no real progress had been made since then.
- Spore allergies have been little studied because it is challenging and difficult to learn, Savolainen explains.
Firstly, spore allergies are relatively rare, and secondly, there are many fungal species. Allergy symptoms are also relatively mild. For these reasons, for example, no allergy tests have been developed for spore allergies, but there has been engaging in other allergies.
According to Vitikainen, the symptoms of spore allergy are mostly caused by mold spores. The most well-known species of small microscopic molds are the spores of Alternaria and Cladosporium molds. Their prevalence is monitored, for example, by the pollen information service Norkko.fi of the Turku Department of Aerobiology(you switch to another use). Norkko also informs when there are a lot of spores of these fungi in the air.
The incidence of mold spores occurs from spring to late summer, while the spores of cap fungi are most abundant during the autumn fungal harvest.
The autumn forest can also distress the life of an asthmatic
Allergy sufferers usually get common respiratory symptoms, such as the runny nose, from a mushroom forest. Instead, people with asthma report symptoms such as shortness of breath.
- When there are spores in the breathing air, and they end up in the mucous membranes of the nose, the immune system may be able to think that something is threatening here and trigger defensive reactions, Vitikainen describes.
However, those suffering from spore allergies get relief when they leave the mushroom forest or at the latest when the frosts come.
Spore allergies can be treated with the usual allergy medicine, which you take before going to the forest. Asymptomatic asthma patient receives help from an asthma medication that opens the bronchi.
- If you know you have been in the forest for a longer time, then an asthma medicine may be necessary, Savolainen suggests.
Warm autumn days can increase the number of spores in the mushroom forest.
Meteorologists now predict warm weather until the end of September and even the beginning of October. Sanna Pätsi, a project researcher at the University of Turku’s pollen information project, says that heat affects the number of spores in fungi in the forest.
Pollen reporting follows the spore counts of two spore species, Cladosporium and Alternaria. At present, the spores of both have already fallen slightly throughout the country.
- However, the numbers can rise moderately momentarily on warm days, Pätsi says
