Abstract

Knowledge of the Finnish aphyllophoroid funga has increased substantially in recent years. In this article, we present two species new to Finland: Spiculogloea subminuta Hauerslev and Typhula suecica I. Olariaga, G. Corriol, I. Salcedo &amp; K. Hansen, and document Sistotrema luteoviride Kotir. &amp; K.-H. Larss. for the third time globally. We also contribute 50 new records of 33 nationally rare species (with a maximum of ten previous records in Finland) and list 52 regionally new species, found for the first time in a certain subzone of the boreal vegetation zone in Finland. Each record is enclosed and contains notes on the substrate. Furthermore, the ecology of the nationally new species and the distribution of rare species are discussed.

Highlights

Aphyllophoroid fungi are an ecological and morphological form group of the Basidiomycota, which consists of morphologically varied fungal subgroups, such as corticioids, polypores, clavarioids, and tremelloids
Spiculogloea subminuta was described based on a single collection in Denmark [30], with Botryobasidium subcoronatum (Höhn. & Litsch.) Donk as the host species
The second Finnish record was found on a fallen Pinus sylvestris trunk in a pine-dominated, middle-aged, xeric heath forest with a forestry history and a low level of dead wood, even though there was some decaying kelo-wood at the landscape level

Summary

Introduction

Aphyllophoroid fungi are an ecological and morphological form group of the Basidiomycota, which consists of morphologically varied fungal subgroups, such as corticioids, polypores, clavarioids, and tremelloids. These groups are highly taxonomically diverse and polyphyletic [1]. A large body of knowledge on the occurrence and distribution of aphyllophoroid species has been accumulated after the first Finnish checklist [2], especially on polypores and corticioids, and on clavarioids (e.g., [3,4,5,6,7,8,9,10,11])
