The algicolous and lichenicolous species Psammina filamentosa is described from the Netherlands and the UK, and is characterized by long (generally over 50 μm) and somewhat tapered conidial arms. Psammina filamentosa is compared with other Psammina specimens found in the same habitat, growing on algae or lichens on the dry side of trees and stones. Psammina filamentosa, P. inflata and P. stipitata differ in the dimensions of their conidial arms. Psammina simplex, however, may be a synonym of P. stipitata, and a DNA study is needed to determine whether it is a distinct species or developing material of P. stipitata. Psammina inflata is also reported as new for the Netherlands. A new worldwide key to the 10 species of Psammina currently known is provided, including three species described from plant material.

一种具有极长分生孢子臂的新 Psammina 物种，具有该属十种已知物种的关键

藻类和地衣类细丝砂粒描述于荷兰和英国，其特点是分生孢子臂长（通常超过 50 微米）和有些锥形的分生孢子臂。细丝砂粒与其他比较砂米娜在同一栖息地发现的标本，生长在树木和石头干燥一侧的藻类或地衣上。Psammina filamentosa, P. inflata和P. stipitata它们的分生孢子臂的尺寸不同。单纯砂粒但是，可能是的同义词P. stipitata, 并且需要进行 DNA 研究来确定它是一个独特的物种还是正在发育的材料P. stipitata.充气沙米也被报道为荷兰的新产品。10个物种的全球新钥匙砂米娜提供了目前已知的，包括从植物材料中描述的三个物种。
