Illuminating type collections of nectriaceous fungi in Saccardo's fungarium
View through CrossRef
Specimens of Nectria spp. and Nectriella rufofusca were obtained from the fungarium of Pier Andrea Saccardo, and investigated via a morphological and molecular approach based on MiSeq technology. ITS1 and ITS2 sequences were successfully obtained from 24 specimens identified
as ' Nectria ' sensu Saccardo (including 20 types) and from the type specimen of Nectriella rufofusca. For Nectria ambigua, N. radians and N. tjibodensis only the ITS1 sequence was recovered. On the basis of morphological and molecular analyses new
nomenclatural combinations for Nectria albofimbriata, N. ambigua, N. ambigua var. pallens, N. granuligera, N. peziza subsp. reyesiana, N. radians, N. squamuligera, N. tjibodensis and new synonymies for N. congesta,
N. flageoletiana, N. phyllostachydis, N. sordescens and N. tjibodensis var. crebrior are proposed. Furthermore, the current classification is confirmed for Nectria coronata, N. cyanostoma, N. dolichospora, N. illudens, N. leucotricha,
N. mantuana, N. raripila and Nectriella rufofusca. This is the first time that these more than 100-yr-old specimens are subjected to molecular analysis, thereby providing important new DNA sequence data authentic for these names.

Title: Illuminating type collections of nectriaceous fungi in Saccardo's fungarium
Description:
Specimens of Nectria spp.
and Nectriella rufofusca were obtained from the fungarium of Pier Andrea Saccardo, and investigated via a morphological and molecular approach based on MiSeq technology.
ITS1 and ITS2 sequences were successfully obtained from 24 specimens identified
as ' Nectria ' sensu Saccardo (including 20 types) and from the type specimen of Nectriella rufofusca.
For Nectria ambigua, N.
radians and N.
tjibodensis only the ITS1 sequence was recovered.
On the basis of morphological and molecular analyses new
