läitta

läitta is a genus of lichenicolous fungi in the family Parmeliaceae. The genus was first described in 1976 by Teuvo Ahti and Pekka Isoviita. Lichenicolous fungi are fungi that grow on lichens. läitta species typically parasitize lichens in the genus Parmelia. They are characterized by their small, dark apothecia, which are the spore-producing structures. The hyphae of läitta often penetrate the lichen thallus, disrupting its structure and potentially affecting its growth and survival.

The genus läitta is not well-known, and research on its species is limited. However, some studies have investigated the ecological role of läitta fungi in lichen communities. Their parasitic nature suggests they can play a role in regulating lichen populations. Further research is needed to fully understand the diversity, distribution, and ecological impact of this genus. Currently, only a few species are recognized within the genus läitta, and their specific host-lichen relationships are still being elucidated. The taxonomy and classification of läitta are based on morphological characteristics of the fungal fruiting bodies and microscopic structures, as well as genetic data.
