Three hundred and fifty woody litter and one hundred and forty seaweed litter sampled from seven beaches of Northwest Portugal were assessed for the filamentous fungal assemblage and diversity. The woody litter was screened for fungi up to 42 months using damp chamber incubation. They consisted of 36 taxa (ascomycetes, 21; basidiomycetes, 3; anamorphic taxa, 12) comprising 10 core group taxa (≥10%) (ascomycetes, 8; basidiomycete, 1; anamorphic taxa, 1). The total fungal isolates ranged between 150 and 243, while the number of fungal taxa per wood ranged between 3 and 4.9. The seaweed litter was screened up to four months in damp chamber incubation. They encompassed 29 taxa (ascomycetes, 16; basidiomycetes, 2; anamorphic taxa, 11) comprising 15 core group taxa (ascomycetes, 9; basidiomycete, 1; anamorphic taxa, 5). Total fungal isolates ranged between 56 and 120, while the number of fungal taxa per seaweed segment ranged between 4.8 and 6.3. Fifteen taxa of ascomycetes, two of basidiomycetes, and four anamorphic taxa were common to wood and seaweed litter. On both the substrates, two arenicolous fungi Arenariomyces trifurcates and Corollospora maritima were the predominant fungi (72.6-85.9%). The species abundance curves showed higher frequency of occurrence of fungal taxa in seaweed than woody litter. Our study revealed rich assemblage and diversity of marine fungi on wood and seaweed litter of Northwest Portugal beaches. The fungal composition and diversity of this survey have been compared with earlier investigations on marine fungi of Portugal coast.
对从葡萄牙西北部七个海滩采集的350份木质凋落物和140份海藻凋落物进行了丝状真菌群落和多样性评估。使用湿室培养法对木质凋落物进行了长达42个月的真菌筛选。它们由36个分类单元组成（子囊菌，21个；担子菌，3个；无性型分类单元，12个），包括10个核心类群分类单元（≥10%）（子囊菌，8个；担子菌，1个；无性型分类单元，1个）。真菌分离物总数在150至243之间，而每份木材的真菌分类单元数量在3至4.9之间。海藻凋落物在湿室培养中筛选了长达四个月。它们包括29个分类单元（子囊菌，16个；担子菌，2个；无性型分类单元，11个），包括15个核心类群分类单元（子囊菌，9个；担子菌，1个；无性型分类单元，5个）。真菌分离物总数在56至120之间，而每个海藻片段的真菌分类单元数量在4.8至6.3之间。木质和海藻凋落物共有15个子囊菌分类单元、2个担子菌分类单元和4个无性型分类单元。在这两种基质上，两种砂生真菌三叉砂生菌和海生珊瑚孢菌是主要真菌（72.6 - 85.9%）。物种丰度曲线显示，真菌分类单元在海藻中的出现频率高于木质凋落物。我们的研究揭示了葡萄牙西北部海滩木质和海藻凋落物上丰富的海洋真菌群落和多样性。已将本次调查的真菌组成和多样性与葡萄牙海岸海洋真菌的早期调查进行了比较。
